578ff8cff4 feat(debug): GUI toggle for DRED verbose logs + macOS mic permission 
DRED verbose logs (off by default — keeps logcat clean in normal use):
- wzp-codec: DRED_VERBOSE_LOGS atomic flag with dred_verbose_logs() /
  set_dred_verbose_logs() helpers
- opus_enc: gate "DRED enabled" + libopus version logs behind the flag
- desktop/src-tauri/engine.rs: gate DredRecvState parse log,
  reconstruction log, classical PLC log, and DRED-counter fields in
  the Android recv heartbeat (non-verbose path still logs basic recv
  stats)
- Tauri commands set_dred_verbose_logs / get_dred_verbose_logs
- Settings panel gets a "DRED debug logs (verbose, dev only)"
  checkbox; preference persists in wzp-settings localStorage and is
  pushed to Rust on save and on app boot

macOS mic permission:
- Add desktop/src-tauri/Info.plist with NSMicrophoneUsageDescription.
  Without it, modern macOS silently denies CoreAudio capture for
  ad-hoc-signed Tauri builds — capture starts but every callback
  hands you zeros. Symptom: phones could not hear desktop client,
  desktop could still hear phones (playout has no TCC gate). The
  Tauri 2 bundler auto-merges this file into WarzonePhone.app's
  Contents/Info.plist on the next build, so first launch will pop
  the standard mic prompt.

16890576fb feat(observability): logcat-visible DRED proof of life on Android 
Adds enough INFO-level logging that an opus-DRED-v2 APK on Android can
be verified end-to-end by reading logcat alone — no debugger, no
Prometheus, no telemetry pipeline required. Three observation points:

1. Encoder construction (opus_enc.rs)
   - Bumped the "DRED enabled" log from debug! to info! so the
     per-call DRED config is in logcat by default. Each call's first
     OpusEncoder construction logs codec, dred_frames, dred_ms,
     loss_floor_pct.
   - Added a one-shot static OnceLock that logs `opusic_c::version()`
     the first time an OpusEncoder is built in the process. This is
     the smoking gun for "is the new libopus actually loaded" — pre-
     Phase-0 audiopus shipped libopus 1.3 with no DRED, post-Phase-0
     should print 1.5.2 here.

2. DRED state ingest (DredRecvState::ingest_opus in
   desktop/src-tauri/src/engine.rs)
   - First successful parse on a call logs immediately so we can see
     "DRED is on the wire" in logcat.
   - Subsequent parses sample every 100th to confirm steady-state
     samples_available without drowning the log.
   - New parses_total / parses_with_data counters track the parse
     rate vs the success rate (a packet without DRED in it returns
     `available == 0`, so a low ratio means the encoder isn't
     emitting DRED bytes).

3. DRED reconstruction events (DredRecvState::fill_gap_to)
   - Every DRED reconstruction logs at INFO with missing_seq,
     anchor_seq, offset_samples, offset_ms, samples_available,
     gap_size, and the running total. These events are rare on a
     clean network and we want to know exactly which gap was filled.
   - First three classical PLC fills + every 50th thereafter log so
     we can see when DRED couldn't cover a gap (offset out of range,
     no good state, or reconstruct error).

4. Recv heartbeat (Android start() in engine.rs)
   - Existing 2-second heartbeat now includes dred_recv,
     classical_plc, dred_parses_with_data, dred_parses_total
     so a steady-state call shows the cumulative counters in
     logcat without parsing.

How to verify on a real call:

  adb logcat -s 'RustStdoutStderr:*' | grep -i 'dred\|libopus version'

Expected output sequence on a successful Opus call:
  - "linked libopus version libopus_version=libopus 1.5.2-..."  (once per process)
  - "opus encoder: DRED enabled codec=Opus24k dred_frames=20 dred_ms=200 loss_floor_pct=15"  (per call)
  - "DRED state parsed from Opus packet seq=N samples_available=4560 ms=95 ..."  (after first DRED-bearing packet)
  - "recv heartbeat (android) ... dred_recv=0 classical_plc=0 dred_parses_with_data=58 dred_parses_total=58"  (every 2s)

If you see "linked libopus version libopus 1.3" — the FFI swap didn't
take. If dred_parses_with_data stays at 0 while dred_parses_total
climbs — the sender isn't emitting DRED (check the encoder's loss
floor and the receiver's libopus version). If gaps trigger
"classical PLC fill" instead of "DRED reconstruction fired" —
DRED state coverage is too small for the observed loss pattern,
and the loss floor or DRED duration policy needs tuning.

Verification:
- cargo check -p wzp-codec -p wzp-client: 0 errors
- cargo check -p wzp-desktop: 0 Rust errors (only the pre-existing
  tauri::generate_context!() proc macro panic on missing ../dist
  which fires at host check time, irrelevant on the remote build)
- cargo test -p wzp-codec --lib: 69 passing (no regressions)

daf7bcd9ba chore(warnings): sweep the workspace — zero warnings on lib + bin targets 
Addressed every rustc warning surfaced by \`cargo check --workspace
--release --lib --bins\` on opus-DRED-v2. Split across three
categories:

## Real bugs surfaced by the audit (fix, don't silence)

- **crates/wzp-relay/src/federation.rs** — the per-peer RTT monitor
  task computed \`rtt_ms\` every 5 s and threw it on the floor. The
  \`wzp_federation_peer_rtt_ms\` gauge has been registered in
  metrics.rs the whole time but was never receiving samples, leaving
  the Grafana panel blank. Wired it up: the task now calls
  \`fm_rtt.metrics.federation_peer_rtt_ms.with_label_values(&[&label_rtt]).set(rtt_ms)\`
  on every sample. Fixes three warnings (\`rtt_ms\`, \`fm_rtt\`,
  \`label_rtt\` were all captured for this task and all dead).

## Dead code removal

- **crates/wzp-relay/src/federation.rs** — removed \`local_delivery_seq:
  AtomicU16\` field and its initializer. It was described in comments
  as "per-room seq counter for federation media delivered to local
  clients" but was declared, initialized to 0, and never read or
  written anywhere else. Genuine half-wired feature; deletable with
  zero behavior change.
- **crates/wzp-relay/src/room.rs** — removed \`let recv_start =
  Instant::now()\` at the top of a recv loop that was never read.
  Separate variable \`last_recv_instant\` already measures the actual
  gap that's used for the \`max_recv_gap_ms\` stat.
- **crates/wzp-client/src/cli.rs** — removed \`let my_fp = fp.clone()\`
  from the signal loop setup. Cloned but never used in any match arm.

## Stub-intent warnings (underscore + explanatory comment)

- **crates/wzp-relay/src/handshake.rs** — \`choose_profile\` hardcodes
  \`QualityProfile::GOOD\` and ignores its \`supported\` parameter.
  Comment already documented "Cap at GOOD (24k) for now — studio
  tiers not yet tested for federation reliability". Renamed to
  \`_supported\`, expanded the comment to explicitly note the future
  plan (pick highest supported ≤ relay ceiling).
- **crates/wzp-relay/src/federation.rs** — \`forward_to_peers\` takes
  \`room_name: &str\` but only uses \`room_hash\`. The caller
  (handle_datagram) passes the name for caller-site symmetry with
  other helpers; kept the param shape and underscored the binding
  with a comment noting it's reserved for future per-name logging.

## Cosmetic fixes

- **crates/wzp-relay/src/event_log.rs** — dropped \`use std::sync::Arc\`
  (unused).
- **crates/wzp-relay/src/signal_hub.rs** — trimmed \`use tracing::{info,
  warn}\` to \`use tracing::info\`. Also removed unnecessary \`mut\` on
  \`hub\` binding in the \`register_unregister\` test.
- **crates/wzp-relay/src/room.rs** — trimmed \`use tracing::{debug,
  error, info, trace, warn}\` to \`{error, info, warn}\`. Also removed
  unnecessary \`mut\` on \`mgr\` binding in the \`room_join_leave\` test.
- **crates/wzp-relay/src/main.rs** — removed unnecessary \`mut\` on the
  \`config\` destructured binding from \`parse_args()\`; and dropped
  \`ref caller_alias\` from the \`DirectCallOffer\` match pattern since
  the relay just forwards the full \`msg\` (caller_alias is preserved
  end-to-end, we don't need to read it on the relay).
- **crates/wzp-crypto/tests/featherchat_compat.rs** — dropped
  \`CallSignalType\` from a \`use wzp_client::featherchat::{...}\`
  (unused in the test body). Note: this test file has pre-existing
  compile errors from SignalMessage schema drift unrelated to this
  sweep; that's tracked separately.

## Crate-level annotation

- **crates/wzp-android/src/lib.rs** — added
  \`#![allow(dead_code, unused_imports, unused_variables, unused_mut)]\`
  with a doc block explaining the crate is dead code since the Tauri
  mobile rewrite. The legacy Kotlin+JNI Android app that consumed
  this crate was replaced by desktop/src-tauri (live Android recv
  path) + crates/wzp-native (Oboe bridge). Rather than piecemeal
  cleanup of a crate that shouldn't be maintained, the whole-crate
  allow keeps CI clean until someone removes the crate entirely. Kills
  all 6 wzp-android warnings (4 unused imports/vars, 1 unused \`mut\`
  on a JNI env param, 1 dead \`command_rx\` field) in one line.

## Not touched

- **deps/featherchat/warzone/crates/warzone-protocol/src/x3dh.rs** —
  3 unused-variable warnings in \`alice_spk_secret\`, \`alice_bundle\`,
  \`bob_bundle_bytes\`. This is a vendored third-party submodule;
  upstream's problem, not ours. Would need to be reported to
  featherchat upstream if we care.

## Verification

- \`cargo check --workspace --release --lib --bins\` → 0 warnings, 0 errors
- \`cargo check --workspace --release --all-targets\` → only the 3
  featherchat submodule warnings remain, plus the pre-existing 3
  broken integration tests (SignalMessage schema drift from Phase 2,
  tracked separately and explicitly out of scope).

df1a45a5f5 fix(cli): port live mode to ring API (read_frame/write_frame removed) 
AudioCapture and AudioPlayback no longer expose the old read_frame()
and write_frame() methods — they were replaced with ring() returning
&Arc<AudioRing> when the lock-free SPSC ring was introduced. The CLI
live-mode loop still referenced the removed methods, which broke every
workspace build that touched wzp-client bin (including the remote
Linux x86_64 docker build).

- Send loop: allocate a 960-sample scratch buffer, fill it in a loop
  via capture.ring().read() until a full 20 ms frame is available,
  sleep 2 ms between empty reads to avoid hot-spinning.
- Recv loop: write decoded PCM into playback.ring() instead of
  calling write_frame(). Short writes on full ring drop the tail,
  which is the correct real-time behavior for CLI live mode.

No behavioral change on the wire or in the call pipeline — this is
purely a compile fix for cli.rs bitrot that accumulated since the
ring API landed.

a7b2f850f1 build(script): parametrize branch via WZP_BRANCH (default opus-DRED-v2) 
The Linux build script was hardcoded to feat/android-voip-client, which
is an older branch that doesn't have the current DRED work or the relay
fixes from 8c4d640. Default the branch to opus-DRED-v2 (current active
development branch), thread it through to the remote script as a third
positional arg, and allow override via `WZP_BRANCH=<name> ./build-linux-docker.sh`.

This is also what let us discover that the relay at 172.16.81.175:4433
was running d0c1731 (android-rewrite) and missing the 8c4d640
CallSetup/advertised-IP fix — direct calls failed until the relay was
rebuilt locally.

575a39d07a fix(deps): restore Cargo.lock from 8ceb6f4 — minimize dep drift from Phase 0 
Phase 0 cherry-pick regenerated the lockfile from scratch via
`cargo generate-lockfile`, which bumped at least tokio (1.50.0 → 1.51.1)
and downgraded the lockfile format from version 4 → version 3. Many
other transitive deps may have shifted silently.

Symptoms that pointed here:
1. Direct-call media QUIC handshake silently stalls for exactly the
   client-side 10s timeout, with no errors in the log. Classic tokio
   runtime / async waker mismatch — tasks queued from one runtime
   never run because the endpoint's I/O driver is on another runtime.
2. Every `place_call` gets an immediate `signal: Hangup reason=Normal`
   back from the signal recv loop, as if it's consuming stale state.
3. Eventually hits `FORTIFY: pthread_mutex_lock called on a destroyed
   mutex` and the process dies.

All three are consistent with a tokio async primitive being shared
across runtimes in a way that tokio 1.51.1 handles differently than
1.50.0 (which was the version on the user's known-good build). Rather
than chase the specific bisection, restore the exact base lockfile
and let cargo add only the three deps Phase 0 actually needs
(opusic-c, opusic-sys, bytemuck).

Verification:
- `git diff 8ceb6f4..HEAD -- Cargo.lock | grep -c '^[+-]version = '` → 0
  (no version-line changes beyond what Cargo auto-pulls for new crates)
- tokio back to 1.50.0
- rustls, quinn, quinn-proto, quinn-udp all unchanged
- Lockfile version restored to 4
- cargo test -p wzp-codec --lib: 69 passing (unchanged)
- cargo test -p wzp-client --lib: 35 passing + 1 ignored (unchanged)

Does not fix the pre-existing relay-side advertised-IP bug
(CallSetup may still contain a relay address that the callee cannot
reach from its network), but that is an orthogonal issue that existed
on 8ceb6f4 too.

d63d50cdc0 fix(build): remove apostrophe from libc++_shared comment (broke docker bash -c quoting) 
Previous commit d269600 added the libc++_shared.so copy step but the
comment block included "Android's dynamic linker" — the apostrophe
closed the enclosing `bash -c '...'` single-quoted string prematurely.
Everything after "Android" was interpreted as wrapper-script bash
instead of docker-container bash, so JNI_ABI_DIR (set inside the
docker context) was unbound when the wrapper tried to use it.

Build failed with:
  /tmp/wzp-tauri-build.sh: line 149: JNI_ABI_DIR: unbound variable

Note the pre-existing script uses backticks in its comments ("cargo-
tauri`s linker wiring") exactly to avoid this trap. Matched that style
and added an explicit NOTE to the comment explaining the quoting
hazard for future editors.

d269600aa7 fix(build): build-tauri-android.sh — copy libc++_shared.so into jniLibs 
Root cause of "wzp-native not loaded" at runtime on opus-DRED-v2 APK:

libwzp_native.so has a NEEDED entry for libc++_shared.so (because
crates/wzp-native/build.rs uses cpp_link_stdlib(Some("c++_shared"))),
but the APK only contained:
    lib/arm64-v8a/libwzp_desktop_lib.so  (192 MB)
    lib/arm64-v8a/libwzp_native.so       (683 KB)

No libc++_shared.so → Android's dynamic linker fails the dlopen of
libwzp_native.so at runtime with "library libc++_shared.so not found",
and every audio path that routes through wzp_native (capture, playout,
register, direct call) refuses to start.

Diagnosis:
- readelf -d libwzp_native.so shows NEEDED libc++_shared.so
- python zipfile listing of the APK confirms libc++_shared.so is
  absent from lib/arm64-v8a/
- scripts/build-and-notify.sh (the legacy wzp-android build path)
  already had this fix at lines 126-134 with an explicit comment:
  "cargo-ndk may not copy libc++_shared.so — grab it from the NDK if
  missing". That fix was never ported to build-tauri-android.sh when
  the Tauri mobile pipeline was set up.

Fix: after `cargo ndk build -p wzp-native --release` produces
libwzp_native.so into jniLibs, copy libc++_shared.so from the NDK
sysroot (same find pattern as build-and-notify.sh) into the same
jniLibs dir. Abort with a clear error if the NDK doesn't have the file.

Also noting the 191 MB vs 359 MB size discrepancy the user saw: that's
almost entirely libwzp_desktop_lib.so being a 192 MB debug build. The
old working APK was probably a release build (smaller main lib) or
included multiple arches (doubling/tripling the .so count). The size
is cosmetic — the crash is the real issue, and libc++_shared.so is
~2 MB so this fix doesn't close the size gap. Can investigate the
size difference separately after register + direct call work again.

dfbe21fe6e feat(tauri-engine): Phase 3b/3c re-port — DRED reconstruction on the live Tauri mobile engine 
The original Phase 3b landed on wzp-client/CallDecoder and Phase 3c
landed on wzp-android/src/engine.rs. Both of those are DEAD CODE on
feat/desktop-audio-rewrite: the legacy Kotlin app in android/app/ is
not built by the Tauri mobile pipeline, and the Tauri engine bypasses
CallDecoder by calling wzp_codec::create_decoder directly.

The live Android call engine lives at desktop/src-tauri/src/engine.rs
with two `pub async fn start<F>` functions — one cfg-gated on Android
(Oboe via wzp-native) and one for desktop (CPAL). Both recv tasks
were using `let mut decoder = wzp_codec::create_decoder(...)` which
returns `Box<dyn AudioDecoder>` and doesn't expose the inherent
`reconstruct_from_dred` method.

Changes:

New helper struct `DredRecvState` at the top of engine.rs, wrapping:
  - DredDecoderHandle (libopus DRED side-channel parser)
  - DredState scratch (for parse_into)
  - DredState last_good (cached valid state, swapped on success)
  - last_good_seq: Option<u16> (DRED anchor sequence)
  - expected_seq: Option<u16> (for gap detection)
  - dred_reconstructions / classical_plc_invocations counters

With three methods:
  - ingest_opus(seq, payload): parse DRED, swap on success
  - fill_gap_to(decoder, current_seq, frame_samples, scratch, emit):
    detect gap back from expected_seq, reconstruct each missing
    frame via DRED if state covers it, fall through to classical
    decoder.decode_lost() when it doesn't. Calls emit() once per
    frame with a slice the caller uses for AGC + playout write.
  - reset_on_profile_switch(): invalidate tracking when codec changes

Both recv tasks (Android @ ~line 297 and desktop @ ~line 907):
  - Decoder type changed from `Box<dyn AudioDecoder>` via
    `wzp_codec::create_decoder` to concrete `AdaptiveDecoder::new(profile)`
    so we can call the inherent reconstruct_from_dred method.
  - Added `use wzp_proto::traits::AudioDecoder;` at the top of
    engine.rs to bring decode/decode_lost/set_profile trait methods
    into scope on the concrete type.
  - New `current_profile` local alongside `current_codec` (used for
    frame_duration lookups that drive the DRED sample offset math).
  - On codec/profile switch, call dred_recv.reset_on_profile_switch()
    because the cached DRED state is tied to the old profile's
    frame rate.
  - For each arriving Opus source packet:
      1. dred_recv.ingest_opus(seq, payload) — parse DRED
      2. dred_recv.fill_gap_to(...) — detect gap and reconstruct
         missing frames, each emitted through a closure that does
         AGC + playout write (wzp_native on Android, playout_ring
         on desktop)
      3. Normal decoder.decode() fallthrough for the current packet
         (unchanged)
  - Codec2 packets skip the DRED path entirely (is_opus() gate) —
    libopus can't reconstruct Codec2 audio.

Ordering invariant: gap reconstruction writes to playout BEFORE the
current packet's decoded audio, preserving temporal order since the
playout ring is FIFO. The closure captures the `spk_muted` flag once
before the gap loop to avoid mid-gap-fill state changes.

Kept `crates/wzp-android/src/engine.rs` and `crates/wzp-android/src/
stats.rs` from the earlier Phase 3c commit as-is — they're dead code
on feat/desktop-audio-rewrite but harmless, and deleting them would
diverge this branch from an independently-useful intermediate state.
The old Phase 3c commit (505a834) stays as historical reference.

Verification:
- cargo check -p wzp-codec -p wzp-client -p wzp-relay: 0 errors
- cargo check -p wzp-desktop: only pre-existing `tauri::generate_context!()`
  panic on missing ../dist (Vite output not built on host) — no Rust
  compile errors from our changes
- cargo test -p wzp-codec --lib: 69 passing (unchanged)
- cargo test -p wzp-client --lib: 35 passing + 1 ignored (unchanged)

Next: scripts/build-tauri-android.sh to get the actual Tauri APK —
NOT build-and-notify.sh which builds the dead legacy android/app.

b83c31b5d1 fix(android): remove duplicate TextAlign import in InCallScreen.kt 
Pre-existing build breakage on feat/desktop-audio-rewrite @ 8ceb6f4 —
TextAlign was imported twice (line 5 and line 50), causing Kotlin
compilation to fail with:

  e: InCallScreen.kt:5:39 Conflicting import, imported name 'TextAlign' is ambiguous
  e: InCallScreen.kt:50:39 Conflicting import, imported name 'TextAlign' is ambiguous

The line-5 copy was squeezed into the middle of the foundation.* block
(alphabetically out of place) — an accidental extra paste. The line-50
copy sits in the correct alphabetical position. Removed the former.

This blocks the APK build for the opus-DRED-v2 rebase. Unrelated to DRED
itself but the error surfaced because the cherry-picked phases caused
a clean Gradle build (no UP-TO-DATE short-circuit) that re-compiled
InCallScreen.kt against the fresh class graph.

Also noting that the previous working APK (unridden-alfonso.apk) was
built from the stale d0c1731 baseline which didn't have this bug —
one more reason the stale-branch build problem went unnoticed until
the opus-DRED-v2 rebase forced a clean Gradle pass.

1f607281fd fix(build): build-and-notify.sh — parameterize branch, fail loud on pull errors 
Same fix that landed on the old opus-DRED branch as c95255d: the remote
build script hardcoded `feat/android-voip-client` and swallowed the
reset failure with `|| true`, silently leaving the tree on whatever
branch was there. This ported the fix forward to feat/desktop-audio-
rewrite (which had the same bug).

Fix:
  Local side:
  - Auto-detect current branch via `git branch --show-current`
  - Accept `--branch NAME` override
  - Pass branch as a third positional arg to the remote script
  - Abort on detached HEAD
  - Updated usage docs for the "build what I'm working on" default

  Remote side:
  - Read BRANCH from $3, abort if empty
  - `git fetch origin "$BRANCH"` — errors surface
  - `git reset --hard "origin/$BRANCH"` — no `|| true`, failures abort
  - Echo the resolved commit hash + subject after reset
  - Notifications include both branch and hash:
    "WZP Android [opus-DRED-v2 @ <hash>] done! APK: ..."

7515417202 feat(telemetry): Phase 4 — LossRecoveryUpdate protocol + relay metrics + DebugReporter 
Phase 4 lays the telemetry foundation for distinguishing DRED recoveries
from classical PLC in production: a new SignalMessage variant, two new
per-session Prometheus counters on the relay side, and a highlighted
loss-recovery section in the Android DebugReporter.

The periodic emitter (client → relay) and Grafana panel are deferred to
Phase 4b — this commit ships the protocol surface, the relay sink, and
the immediate user-visible debug output. Once 4b lands the full path
(emitter → relay → Prometheus → Grafana), the metrics here will
automatically start receiving data.

Scope decision — why not extend QualityReport instead:
The existing wire-format QualityReport is a fixed 4-byte media packet
trailer. Adding counter fields to it would shift the binary layout and
break backward compatibility (old receivers would parse the last 4
bytes of the extended trailer as QR, corrupting audio). Using a
new SignalMessage variant on the reliable QUIC signal stream sidesteps
the wire-format problem entirely — serde JSON enums tolerate unknown
variants gracefully on old receivers, and the signal channel is the
right layer for periodic telemetry aggregates.

Changes:

  wzp-proto/src/packet.rs:
    - New SignalMessage::LossRecoveryUpdate variant carrying:
        * dred_reconstructions: u64 (monotonic since call start)
        * classical_plc_invocations: u64 (monotonic)
        * frames_decoded: u64 (for rate calculation)
    - All three fields tagged #[serde(default)] for forward compat.

  wzp-client/src/featherchat.rs:
    - Added a match arm so signal_to_call_type() handles the new
      variant (treat as Offer for featherChat bridging purposes).

  wzp-relay/src/metrics.rs:
    - Two new IntCounterVec metrics on the relay, labeled by session_id:
        * wzp_relay_session_dred_reconstructions_total
        * wzp_relay_session_classical_plc_total
    - New method update_session_loss_recovery(session_id, dred, plc)
      applies monotonic deltas: if the incoming totals exceed the
      current counter, the difference is inc_by'd. If the incoming
      totals are LOWER (client restart or counter reset), the
      Prometheus counter holds steady until the client catches up.
      This matches the existing update_session_buffer delta pattern.
    - remove_session_metrics() now cleans up the two new labels.
    - New test session_loss_recovery_monotonic_delta exercises:
        * initial population (10 DRED, 2 PLC)
        * forward advance (25, 5 → delta +15, +3)
        * lower values ignored (client reset → counters unchanged)
        * client catches up (30, 8 → advances to new max)
    - Existing session_metrics_cleanup test extended to cover the
      new counters.

  android/app/src/main/java/com/wzp/debug/DebugReporter.kt:
    - Phase 4 users — and incident responders — need to quickly see
      whether DRED is actually firing during a call. The stats JSON
      already carries the counters (after Phase 3c), but they were
      buried in the trailing JSON dump. Added a dedicated
      "=== Loss Recovery ===" section to the meta preamble that
      extracts dred_reconstructions, classical_plc_invocations,
      frames_decoded, and fec_recovered from the JSON and displays
      them plainly, plus computed percentages when frames_decoded > 0.
    - New extractLongField helper: tiny hand-rolled JSON integer
      extractor. We don't want to pull in a full JSON parser for this
      single use case and CallStats has a flat, well-known schema.

505a834c5b feat(codec): Phase 3c — Android engine.rs DRED reconstruction on packet loss 
Phase 3c mirrors Phase 3b on the Android receive path. With Phase 0-3b
landed on desktop + Android encoder, this commit completes codec-layer
loss recovery on the Android decoder side.

Architectural difference vs desktop: engine.rs has NO jitter buffer.
The recv task reads packets directly from the transport via
recv_media().await and writes decoded audio straight into the playout
ring. There is no PlayoutResult::Missing equivalent. Gap detection
therefore has to be done via sequence-number tracking — when a packet
arrives with seq > expected_seq, the frames in between are missing and
we attempt to reconstruct them via DRED before decoding the newly-
arrived packet.

Implementation:

  Imports & types:
    - Added wzp_codec::AdaptiveDecoder, wzp_codec::dred_ffi::{
      DredDecoderHandle, DredState} imports.
    - Changed the `decoder` local from Box<dyn AudioDecoder> (via
      wzp_codec::create_decoder) to concrete AdaptiveDecoder::new(profile).
      Same reasoning as Phase 3b: reconstruct_from_dred is an inherent
      method, not a trait method, so we need the concrete type.

  Recv task state (all task-local, no new struct fields):
    - dred_decoder: DredDecoderHandle
    - dred_parse_scratch: DredState (reused, overwritten per parse)
    - last_good_dred: DredState (cached most-recent valid state)
    - last_good_dred_seq: Option<u16>
    - expected_seq: Option<u16> (for gap detection)
    - dred_reconstructions: u64 (telemetry)
    - classical_plc_invocations: u64 (telemetry)

  Recv loop body (Opus source packets only):
    1. Parse DRED from the new packet first so last_good_dred reflects
       the freshest state available for gap recovery.
    2. Detect a gap: gap = pkt.seq.wrapping_sub(expected_seq). Cap at
       MAX_GAP_FRAMES = 16 (320 ms) to avoid huge wraparound scenarios.
    3. For each missing seq in the gap:
         offset = (last_good_dred_seq - missing_seq) * frame_samples
         if 0 < offset <= last_good_dred.samples_available():
             reconstruct_from_dred + write to playout ring
             bump dred_reconstructions
         else:
             decoder.decode_lost (classical PLC) + write + bump plc counter
    4. Decode the current packet normally and write to playout ring
       (unchanged from Phase 2).
    5. Update expected_seq = pkt.seq.wrapping_add(1).

  Profile-switch handling: when the incoming codec changes (triggering
  decoder.set_profile), reset last_good_dred_seq and expected_seq to
  None. The cached DRED state is tied to the old profile's frame rate
  and would produce wrong offsets after the switch; starting fresh is
  correct.

  Decode-error fallback: the existing `Err(e) => decode_lost` branch
  now also increments classical_plc_invocations so the counter
  accurately reflects all PLC invocations (gap-detected AND decode-
  error-triggered).

Telemetry (CallStats additions):
  - stats.dred_reconstructions: u64
  - stats.classical_plc_invocations: u64
  Both updated on every packet arrival in the existing stats.lock()
  block alongside frames_decoded/fec_recovered, so the Android UI and
  JNI bridge already have these values without any further plumbing.
  The periodic recv stats log now includes both counters.

Ordering note: DRED gap reconstruction happens BEFORE decoding the new
packet's audio because the playout ring is FIFO. Gap samples must be
written before the new packet's samples so temporal order is preserved.
Out-of-order late arrivals (seq < expected_seq) are naturally dropped
as stale by the gap detection (gap would be a large wraparound value
exceeding MAX_GAP_FRAMES).

Verification:
- cargo check --workspace: zero errors
- cargo test -p wzp-codec --lib: 68 passing (unchanged from Phase 3b)
- cargo test -p wzp-client --lib: 35 passing (unchanged from Phase 3b)
- cargo check -p wzp-android --lib: zero errors
- cargo test -p wzp-android cannot run on macOS host (pre-existing
  -llog linker dep, unrelated). Real end-to-end verification happens
  via the Android APK build on the remote Docker builder
  (scripts/build-and-notify.sh).

27bc264738 feat(codec): Phase 3b — CallDecoder DRED reconstruction on packet loss 
Phase 3b of the DRED integration — wires the Phase 3a FFI primitives
into the desktop receive path. When the jitter buffer reports a missing
Opus frame, CallDecoder now attempts to reconstruct the audio from the
most recently parsed DRED side-channel state before falling through to
classical PLC.

Architectural refinement vs the PRD's literal wording: the PRD said
"jitter buffer takes a Box<dyn DredReconstructor>". After checking deps,
wzp-transport depends only on wzp-proto (not wzp-codec). Putting DRED
state in the jitter buffer would require a new cross-crate dep and
couple the codec-agnostic buffer to libopus. Instead, this commit keeps
the DRED state ring and reconstruction dispatch inside CallDecoder (one
layer up from the jitter buffer), intercepting the existing
PlayoutResult::Missing signal. Same lookahead/backfill semantics,
cleaner layering, zero change to wzp-transport.

Changes:

  CallDecoder field type: Box<dyn AudioDecoder> → AdaptiveDecoder.
  Required because Phase 3b calls the inherent reconstruct_from_dred
  method, which cannot live on the AudioDecoder trait without dragging
  libopus DredState through wzp-proto. In practice AdaptiveDecoder was
  the only AudioDecoder implementor anyway — the trait abstraction was
  buying nothing. Method call sites unchanged because AdaptiveDecoder
  also implements AudioDecoder.

  New CallDecoder fields:
    - dred_decoder: DredDecoderHandle
    - dred_parse_scratch: DredState  (scratch for parse_into)
    - last_good_dred: DredState      (cached most-recent valid state)
    - last_good_dred_seq: Option<u16>
    - dred_reconstructions: u64      (Phase 4 telemetry)
    - classical_plc_invocations: u64 (Phase 4 telemetry)

  CallDecoder::ingest — on Opus non-repair packets, parse DRED into the
  scratch state. On success (samples_available > 0), std::mem::swap the
  scratch into last_good_dred and record the seq. This is O(1) per
  packet, zero allocation after construction (the two DredState buffers
  are allocated once in new() and reused forever).

  CallDecoder::decode_next — on PlayoutResult::Missing(seq) for Opus
  profiles: if last_good_dred_seq > seq and the seq delta × frame_samples
  fits within samples_available, call audio_dec.reconstruct_from_dred
  and bump dred_reconstructions. Otherwise fall through to classical
  PLC and bump classical_plc_invocations. The Codec2 path always falls
  through to classical PLC since DRED is libopus-only and
  AdaptiveDecoder::reconstruct_from_dred rejects Codec2 tiers
  explicitly.

  OpusDecoder and AdaptiveDecoder: new inherent reconstruct_from_dred
  method that delegates to the underlying DecoderHandle. Needed to
  bridge CallDecoder's wzp-client code to the Phase 3a FFI wrappers
  without touching the AudioDecoder trait.

CRITICAL FINDING — raised DRED loss floor from 5% to 15%:

Phase 3b testing discovered that libopus 1.5's DRED emission window
scales aggressively with OPUS_SET_PACKET_LOSS_PERC. Empirical data
(see probe_dred_samples_available_by_loss_floor, an #[ignore]'d
diagnostic test in call.rs):

  loss_pct   samples_available   effective_ms
    5%        720                  15 ms  (useless!)
   10%        2640                 55 ms
   15%        4560                 95 ms
   20%        6480                135 ms
   25%+       8400 (capped)       175 ms  (~87% of 200 ms configured)

The Phase 1 default of 5% produced only a 15 ms reconstruction window
— too small to even cover a single 20 ms Opus frame. DRED was
effectively disabled even though it was emitting bytes. Raised the
floor to 15% (95 ms window) as the minimum that actually provides
single-frame loss recovery. This updates Phase 1's DRED_LOSS_FLOOR_PCT
constant in opus_enc.rs and the accompanying module docstring.

Trade-off: 15% assumed loss slightly increases encoder bitrate overhead
on clean networks. Measured via the existing phase1 bitrate probe:

  Before (5% floor):  3649 bytes/sec at Opus 24k + 300 Hz sine
  After  (15% floor): 3568 bytes/sec at Opus 24k + 300 Hz sine

The delta is within noise — 15% isn't meaningfully more expensive than
5% on this signal, which suggests the DRED emission size is signal-
dependent rather than loss-dependent for small values. Net result: we
get a 6x larger reconstruction window for essentially free.

Tests (+3 DRED recovery, +1 #[ignore]'d probe):
- opus_single_packet_loss_is_recovered_via_dred — full encode → ingest
  → decode_next loop with one packet dropped mid-stream. Asserts
  dred_reconstructions ≥ 1 and observes the exact counter deltas.
- opus_lossless_ingest_never_triggers_dred_or_plc — baseline behavior,
  lossless stream never takes the Missing branch.
- codec2_loss_falls_through_to_classical_plc — Codec2 never
  reconstructs via DRED even if state were populated (which it won't
  be — Codec2 packets don't carry DRED bytes).
- probe_dred_samples_available_by_loss_floor — #[ignore]'d diagnostic
  that sweeps loss_pct values and prints the resulting DRED window
  sizes. Kept for future tuning work.

New CallDecoder introspection accessors (public but undocumented in
the PRD): last_good_dred_seq() and last_good_dred_samples_available()
for test diagnostics and future telemetry surfaces in Phase 4.

Verification:
- cargo check --workspace: zero errors
- cargo test -p wzp-codec --lib: 68 passing (Phase 3a baseline held)
- cargo test -p wzp-client --lib: 35 passing (+3 Phase 3b tests,
  +1 ignored diagnostic, no regressions)

Next up: Phase 3c mirrors this on the Android engine.rs receive path.

c27b39d553 feat(codec): Phase 3a — DRED FFI primitives (DredDecoderHandle + DredState) 
Phase 3a of the DRED integration — the foundation for codec-layer loss
recovery. Adds three new safe wrappers to crates/wzp-codec/src/dred_ffi.rs
over the raw opusic-sys FFI, plus the reconstruction method on the existing
DecoderHandle. No call-site integration yet — that lands in Phase 3b (desktop)
and Phase 3c (Android).

New types:
- `DredDecoderHandle`: owns *mut OpusDREDDecoder from opus_dred_decoder_create.
  Used for parsing DRED side-channel data out of arriving Opus packets.
  This is a SEPARATE libopus object from OpusDecoder — it has its own
  internal state. Freed via opus_dred_decoder_destroy on Drop.
- `DredState`: owns *mut OpusDRED from opus_dred_alloc (a fixed ~10.6 KB
  buffer per libopus 1.5). Holds parsed DRED data between the parse and
  reconstruct steps. Reusable — parse_into overwrites contents. Tracks
  samples_available as a cached u32 so callers don't thread the value
  separately. Freed via opus_dred_free on Drop.

New methods:
- `DredDecoderHandle::parse_into(&mut self, state: &mut DredState, packet)`
  wraps opus_dred_parse with max_dred_samples=48000 (1s max), sampling_rate
  =48000, defer_processing=0. Returns the positive sample offset of the
  first decodable DRED sample, 0 if no DRED is present, or an error.
  Populates state.samples_available so subsequent reconstruct calls know
  the valid offset range.
- `DecoderHandle::reconstruct_from_dred(&mut self, state, offset_samples,
  output)` wraps opus_decoder_dred_decode. Reconstructs audio at a specific
  sample position (positive, measured backward from the DRED anchor packet)
  into a caller-provided output buffer. Validates that 0 < offset_samples
  <= state.samples_available() before calling the FFI to catch range bugs.

Tests (+7, wzp-codec total: 68 passing):
- dred_decoder_handle_creates_and_drops
- dred_state_creates_and_drops
- dred_state_reset_zeroes_counter
- dred_parse_and_reconstruct_roundtrip — end-to-end validation. Encodes
  60 frames of a 300 Hz sine wave through a DRED-enabled Opus 24k encoder,
  parses DRED state out of each arriving packet, asserts that at least one
  packet carries non-zero samples_available (DRED warm-up completes within
  the first second), then reconstructs 20 ms of audio from inside the
  window and asserts non-zero total energy. This is the hard signal that
  the full libopus 1.5 DRED FFI chain is correctly wired on our side.
- reconstruct_with_out_of_range_offset_errors — offset > samples_available
  is rejected at the Rust layer before the FFI call.
- reconstruct_with_zero_offset_errors — offset <= 0 rejected.
- dred_parse_empty_packet_returns_zero — graceful handling of empty input.

Architectural note (divergence from PRD's literal wording):
The PRD said "jitter buffer takes a Box<dyn DredReconstructor>". After
checking Cargo.toml for wzp-transport, it does NOT depend on wzp-codec —
only wzp-proto. Adding a DRED state ring inside the jitter buffer would
require a new cross-crate dependency and couple the codec-agnostic jitter
buffer to libopus internals. Instead, Phase 3b will put the DRED state
ring and reconstruction dispatch in CallDecoder (one layer up from the
jitter buffer), intercepting the existing PlayoutResult::Missing signal
and attempting reconstruction before falling through to classical PLC.
The jitter buffer itself stays unchanged. Same lookahead/backfill
semantics, cleaner layering. PRD's intent preserved, implementation
refined.

Verification:
- cargo check --workspace: zero errors
- cargo test -p wzp-codec --lib: 68 passing (61 Phase 2 baseline + 7 new)
- The roundtrip test is the acceptance gate — it proves that
  opus_dred_decoder_create, opus_dred_alloc, opus_dred_parse, and
  opus_decoder_dred_decode all work correctly through our wrappers on
  real libopus 1.5.2 output.

6db5c25b54 feat(codec): Phase 2 — remove RaptorQ from Opus tiers, Codec2 unchanged 
Phase 2 of the DRED integration (docs/PRD-dred-integration.md). With
Phase 1 having enabled DRED on every Opus profile, the app-level RaptorQ
layer is now redundant overhead on those tiers: +20% bitrate, +40–100 ms
receive-side latency (block wait), +CPU for stats we never used. This
phase removes RaptorQ from the Opus encode and decode paths on both the
desktop (wzp-client/call.rs) and Android (wzp-android/engine.rs) sides.
Codec2 tiers keep RaptorQ with their current ratios unchanged — DRED is
libopus-only and Codec2 has no neural equivalent.

Encoder changes (the real bandwidth / CPU win):
- CallEncoder::encode_frame and engine.rs encode loop now gate the
  RaptorQ path on !codec.is_opus():
    - Opus source packets emit fec_block=0, fec_symbol=0,
      fec_ratio_encoded=0 in the MediaHeader
    - fec_enc.add_source_symbol is skipped on Opus
    - generate_repair + repair packet emission is skipped on Opus
    - block_id and frame_in_block counters stay frozen at 0 for Opus
- Codec2 path is byte-for-byte identical to pre-Phase-2 behavior.

Decoder changes (mostly cleanup, since both live decoder paths were
already reading audio directly from source packets and only using the
RaptorQ decoder output for stats):
- CallDecoder::ingest skips fec_dec.add_symbol on Opus packets. Source
  packets still flow to the jitter buffer; Opus repair packets from old
  senders are dropped cleanly (repair packets never hit the jitter
  buffer either).
- engine.rs recv loop skips fec_dec.add_symbol, fec_dec.try_decode, and
  fec_dec.expire_before on Opus packets. The `fec_recovered` stat
  counter becomes Codec2-only (a separate DRED reconstruction counter
  lands in Phase 4).

Wire-format backward compat verified at pre-flight:
- Old receiver + new sender: engine.rs pipeline.rs path gates on
  non-zero fec_block/fec_symbol which now never fire for Opus, so the
  RaptorQ decoder simply isn't fed. Audio flows normally. Desktop
  CallDecoder's old path accumulated packets into the stale-eviction
  HashMap, which cleans up after 2s — harmless.
- New receiver + old sender: new receiver skips RaptorQ on Opus so
  old-sender repair packets are ignored entirely (no crash, no double-
  decode). Loses the (previously vestigial) RaptorQ recovery benefit,
  which was never actually active in the audio path. Source packets
  still decode normally.
- No wire format version bump required. MediaHeader is unchanged; we
  just zero the FEC fields on Opus packets.

Test changes:
- Removed `encoder_generates_repair_on_full_block` — asserted the old
  (pre-Phase-2) RaptorQ-on-Opus behavior and is now incorrect. Replaced
  with two symmetric tests:
    - `opus_source_packets_have_zero_fec_header_fields` — verifies
      Phase 2 invariants on Opus packets
    - `opus_encoder_never_emits_repair_packets` — runs 20 frames of
      non-silent sine wave through a GOOD-profile encoder, asserts
      exactly 20 output packets, zero repair
    - `codec2_encoder_generates_repair_on_full_block` — same shape as
      the old test but on CATASTROPHIC profile (Codec2 1200, 8
      frames/block, ratio 1.0) to verify Codec2 path still emits
      repairs as before

Verification:
- cargo check --workspace: zero errors
- cargo test -p wzp-codec --lib: 61 passing (Phase 1 baseline held)
- cargo test -p wzp-client --lib: 32 passing (+3 new Phase 2 tests,
  -1 old test removed)
- cargo check -p wzp-android --lib: zero errors (host link of
  wzp-android tests fails on -llog per pre-existing Android-only
  build.rs, unrelated to this work; integration build via
  build-and-notify.sh will validate Android end-to-end)
- Pre-existing broken integration test in
  crates/wzp-client/tests/handshake_integration.rs (SignalMessage
  schema drift) is NOT caused by this commit — baseline had the same
  3 compile errors before Phase 2. Flagged as a separate cleanup task.

Expected observable effects on a real call:
- Opus 24k outgoing bitrate drops from ~28.8 kbps (ratio 0.2 RaptorQ)
  to ~25 kbps (base 24 kbps + DRED ~1–10 kbps signal-dependent)
- Opus receive-side latency drops ~40 ms on clean network (no more
  block wait — jitter buffer emits as soon as a source packet arrives)
- Codec2 calls show no latency or bitrate change

54cbebd34e feat(codec): Phase 1 — enable DRED on all Opus profiles, disable inband FEC 
Phase 1 of the DRED integration (docs/PRD-dred-integration.md). The Opus
encoder now emits DRED (Deep REDundancy) bytes in every packet, carrying
a neural-coded history of recent audio that the decoder can use to
reconstruct loss bursts up to the configured window. Opus inband FEC
(LBRR) is disabled because DRED does the same job better and running both
wastes bitrate on overlapping protection.

Tiered DRED duration policy per PRD:
  Studio  (Opus 32k/48k/64k): 10 frames = 100 ms
  Normal  (Opus 16k/24k):     20 frames = 200 ms
  Degraded (Opus 6k):         50 frames = 500 ms

Each profile switch (via adaptive quality) updates the DRED duration to
match the new tier. A 5% packet_loss floor is applied whenever DRED is
active, because libopus 1.5 gates DRED emission on non-zero packet_loss.
Real loss measurements from the quality adapter override upward.

Escape hatch: AUDIO_USE_LEGACY_FEC=1 reverts the encoder to Phase 0
behavior (inband FEC Mode1, DRED off, no loss floor). Read once at
OpusEncoder::new; call-scoped, not re-read mid-call. Trait-level
set_inband_fec becomes a no-op in DRED mode to preserve the invariant
even if external callers forget.

Observations from the bitrate probe test (dred_mode_roundtrip_voice_pattern):
  DRED mode:   3649 bytes/sec (~29.2 kbps) on Opus 24k + 300 Hz sine
  Legacy mode: 2383 bytes/sec (~19.1 kbps)
  Delta:       +10.1 kbps

The delta is considerably larger than the "+1 kbps flat" figure I carried
into the PRD from hazy memory of published DRED benchmarks. Likely because
the input (300 Hz sine) is very compressible so the base Opus rate in
legacy mode is well below the 24 kbps target, making the delta look
disproportionate. Signal-dependent — real speech would probably show a
different ratio. If production telemetry shows the overhead is excessive,
we can cut DRED duration on the normal tier from 200 ms to 100 ms as a
first tuning lever. Not blocking Phase 1 since the test still passes
within the reasonable 2000–8000 bytes/sec bounds.

Test changes (+8 tests, total wzp-codec: 61 passing):
- dred_duration_for_studio_tiers_is_100ms  (per-profile policy)
- dred_duration_for_normal_tiers_is_200ms
- dred_duration_for_degraded_tier_is_500ms
- dred_duration_for_codec2_is_zero
- default_mode_is_dred_not_legacy  (sanity check on fresh construction)
- dred_mode_roundtrip_voice_pattern  (observes DRED bitrate, asserts bounds)
- profile_switch_refreshes_dred_duration  (verifies set_profile updates DRED)
- set_inband_fec_noop_in_dred_mode  (trait-level inband FEC no-op)

Verification:
- cargo check --workspace: zero errors, no new warnings
- cargo test -p wzp-codec: 61/61 passing (53 pre-Phase-1 baseline + 8 new)
- Empirical DRED bitrate observed via `rtk proxy cargo test
  dred_mode_roundtrip_voice_pattern -- --nocapture`

86526a7ad4 feat(codec): Phase 0 — swap audiopus → opusic-c + opusic-sys (libopus 1.5.2) 
Phase 0 of the DRED integration (docs/PRD-dred-integration.md). No behavior
change: inband FEC stays ON, no DRED, same bitrate, same quality. This
commit unblocks Phase 1+ by getting us onto libopus 1.5.2 where DRED lives.

Rationale for going straight to a custom DecoderHandle: opusic-c::Decoder's
inner *mut OpusDecoder pointer is pub(crate), so we cannot reach it for the
Phase 3 DRED reconstruction path. Running two parallel decoders (one for
audio, one for DRED) would drift because the DRED decoder wouldn't see
normal decode calls. Single unified DecoderHandle over raw opusic-sys is
the only correct architecture, so we build it in Phase 0 rather than
rewriting opus_dec.rs twice.

Changes:
- Cargo.toml (workspace + wzp-codec): remove audiopus 0.3.0-rc.0, add
  opusic-c 1.5.5 (bundled + dred features), opusic-sys 0.6.0 (bundled),
  bytemuck 1. Pinned exactly for reproducible libopus 1.5.2.
- opus_enc.rs: rewritten against opusic_c::Encoder. Argument order for
  Encoder::new swapped (Channels first). set_inband_fec(bool) now maps
  to InbandFec::Mode1 (the libopus 1.5 equivalent of 1.3's LBRR). encode
  uses bytemuck::cast_slice<i16,u16> at the &[u16] boundary.
- dred_ffi.rs (new): DecoderHandle wrapping *mut OpusDecoder directly via
  opusic-sys. Owns the allocation, frees on Drop. Exposes decode,
  decode_lost, and a pub(crate) as_raw_ptr() for the future Phase 3 DRED
  reconstruction. Send+Sync justified via &mut self access discipline.
- opus_dec.rs: rewritten as a thin AudioDecoder impl over DecoderHandle.
  Behavior identical to pre-swap.

Verification (Phase 0 acceptance gates):
- cargo check --workspace: clean (30 pre-existing warnings in jni_bridge.rs
  unrelated to this work; zero in changed files).
- cargo test -p wzp-codec: 53 tests pass (50 pre-swap + 6 new: 3 in
  dred_ffi.rs for DecoderHandle lifecycle, 3 in opus_enc.rs for version
  check and roundtrip).
- linked_libopus_is_1_5 test asserts opusic_c::version() contains "1.5" —
  hard signal that the swap landed correctly.

56e3417063 docs: add PRD for DRED integration and Opus-tier FEC simplification 
Plans the libopus 1.5.2 upgrade (audiopus → opusic-c/opusic-sys), DRED
enablement with tiered durations (100/200/500ms studio/normal/degraded),
removal of RaptorQ and Opus inband FEC from the Opus tiers, jitter buffer
lookahead/backfill refactor, and runtime escape hatch for rollout safety.
RaptorQ + current ratios preserved on Codec2 tiers (no DRED there).

Includes pre-flight verification findings: opusic-c Decoder inner pointer
is inaccessible (requires unified opusic-sys DecoderHandle), libopus 1.5
DRED API semantics clarified against xiph/opus opus.h, wire-format
backward compat verified on both live receive paths.

//! Raw opusic-sys FFI wrappers for libopus 1.5.2 decoder + DRED reconstruction.
//!
//! # Why this module exists
//!
//! We cannot use `opusic_c::Decoder` because its inner `*mut OpusDecoder`
//! pointer is `pub(crate)` — not reachable from outside the opusic-c crate.
//! Phase 3 of the DRED integration needs to hand that same pointer to
//! `opus_decoder_dred_decode`, and running two parallel decoders (one from
//! opusic-c for normal audio, another from opusic-sys for DRED) would cause
//! the DRED-only decoder's internal state to drift out of sync with the
//! audio stream because it would not see normal decode calls.
//!
//! The fix is to own the raw decoder ourselves and use the same handle for
//! both normal decode AND DRED reconstruction. This module is the single
//! owner of `*mut OpusDecoder`, `*mut OpusDREDDecoder`, and `*mut OpusDRED`
//! in the WZP workspace.
//!
//! # Phase 3a scope
//!
//! Phase 0 added `DecoderHandle` (normal decode). Phase 3a adds:
//! - [`DredDecoderHandle`] — wraps `*mut OpusDREDDecoder` for parsing DRED
//! side-channel data out of arriving Opus packets.
//! - [`DredState`] — wraps `*mut OpusDRED` (a fixed 10,592-byte buffer
//! allocated by libopus) that holds parsed DRED state between the parse
//! and reconstruct steps.
//! - [`DredDecoderHandle::parse_into`] — wraps `opus_dred_parse`.
//! - [`DecoderHandle::reconstruct_from_dred`] — wraps `opus_decoder_dred_decode`.
//!
//! The pattern is: on every arriving Opus packet, the receiver calls
//! `parse_into` with a reusable `DredState`, then stores (seq, state_clone)
//! in a ring. On detected loss, the receiver computes the offset from the
//! freshest reachable DRED state and calls `reconstruct_from_dred` to
//! synthesize the missing audio.

//! Opus encoder wrapping the `audiopus` crate. //! Opus encoder wrapping the `opusic-c` crate (libopus 1.5.2).
//!
//! Phase 1 of the DRED integration: encoder-side DRED is enabled on every
//! Opus profile with a tiered duration (studio 100 ms / normal 200 ms /
//! degraded 500 ms), and Opus inband FEC (LBRR) is disabled because DRED
//! is the stronger mechanism for the same failure mode. The legacy behavior
//! is preserved behind the `AUDIO_USE_LEGACY_FEC` environment variable as a
//! runtime escape hatch for rollout. See `docs/PRD-dred-integration.md`.
//!
//! # DRED duration policy
//!
//! Rationale from the PRD:
//! - Studio tiers (Opus 32k/48k/64k): 100 ms — loss is rare on high-quality
//! networks; short window keeps decoder CPU modest.
//! - Normal tiers (Opus 16k/24k): 200 ms — balanced baseline covering common
//! VoIP loss patterns (20–150 ms bursts from wifi roam, transient congestion).
//! - Degraded tier (Opus 6k): 500 ms — users on 6k are by definition on a
//! bad link; longer DRED buys maximum burst resilience where it matters.
//!
//! # Why the 15% packet loss floor
//!
//! libopus 1.5's DRED emitter is gated on `OPUS_SET_PACKET_LOSS_PERC` and
//! scales the emitted window proportionally to the assumed loss:
//!
//! ```text
//! loss_pct samples_available effective_ms
//! 5% 720 15
//! 10% 2640 55
//! 15% 4560 95
//! 20% 6480 135
//! 25%+ 8400 (capped) 175 (≈ 87% of the 200ms configured max)
//! ```
//!
//! Measured empirically against libopus 1.5.2 on Opus 24k / 200 ms DRED
//! duration during Phase 3b. At 5% loss the window is only 15 ms — too
//! small to even reconstruct a single 20 ms Opus frame. 15% gives 95 ms
//! (enough for single-frame recovery plus modest burst margin) while
//! keeping the bitrate overhead modest compared to 25%. Real measurements

# PRD: DRED Integration & Opus-Tier FEC Simplification
## Problem
WarzonePhone's audio loss-recovery stack is built around classical Opus + application-level RaptorQ FEC. It was the right answer when WZP was designed, but libopus 1.5 (December 2023) introduced **Deep REDundancy (DRED)** — a neural speech-recovery feature that is strictly better than classical FEC for the loss patterns VoIP calls actually experience. We are paying real latency, bitrate, and complexity costs for protection that DRED now does better and cheaper.
Concretely, on every Opus call today we pay:
- **~40–100 ms of receiver-side latency** waiting for RaptorQ block completion before decode
- **10–20% bitrate overhead** from RaptorQ repair symbols (more on studio profiles)
- **~20–40% codec-internal overhead** from Opus inband FEC (LBRR)
- Classical Opus PLC on loss bursts exceeding the RaptorQ block size — which sounds robotic and gap-ridden
…in exchange for bit-exact recovery of isolated single-frame losses, which is perceptually indistinguishable from classical Opus PLC for 20 ms of speech. The protection is misaligned with the failure modes.
DRED delivers:
- **Zero added receive latency** — reconstruction runs only on detected loss
- **~1 kbps flat bitrate overhead** regardless of base bitrate
- **Plausible reconstruction of bursts up to ~1 second** — DRED's headline capability, exactly the regime RaptorQ can't touch
- Neural PLC that sounds like continuous speech, not a gap
We also have a second, unrelated problem blocking adoption: our FFI crate `audiopus_sys 0.2.2` vendors **libopus 1.3**, predating DRED entirely. We cannot enable DRED without first swapping the FFI layer. The naïve choice (`opus` crate from SpaceManiac) is a trap — it depends on the same dead `audiopus_sys`. The real target is `opusic-c 1.5.5` by DoumanAsh, which vendors libopus 1.5.2 with full DRED support and documents Android NDK cross-compile.
This PRD covers the FFI swap, DRED enablement, the decision to **remove RaptorQ and Opus inband FEC from the Opus tiers entirely** (keeping RaptorQ only for Codec2 where DRED is N/A), and the jitter buffer refactor that the DRED lookahead/backfill pattern requires.
## Goals
- Replace `audiopus 0.3.0-rc.0` + `audiopus_sys 0.2.2` (dead upstream, libopus 1.3) with `opusic-c 1.5.5` + `opusic-sys 0.6.0` (active upstream, libopus 1.5.2)
- Enable DRED on every Opus profile with a tiered duration policy, lower at studio bitrates and higher at degraded bitrates
- Disable Opus inband FEC (LBRR) on all Opus profiles — opusic-c's own docs recommend this, and it overlaps DRED's job
- Remove `wzp-fec` (RaptorQ) from the Opus tiers entirely — the latency and bitrate savings are real, and DRED strictly dominates it on speech
- Keep RaptorQ + current FEC ratios on the Codec2 tiers unchanged — DRED is libopus-only, Codec2 has no neural equivalent
- Refactor `wzp-transport::jitter` to a lookahead/backfill pattern that lets DRED reconstruct loss windows when the next packet arrives, instead of the current "wait for block completion or fall through to classical PLC" policy
- Ship behind a runtime escape hatch (`AUDIO_USE_LEGACY_FEC`) for the first rollout window so we can revert to RaptorQ if DRED has surprises in real-world conditions
## Non-goals
- Changing Codec2 at all. Codec2 1200 / 3200 are outside the DRED lineage and keep their current RaptorQ protection, block sizes, and PLC path.
- Adding new Opus bitrate tiers or changing the quality adaptation thresholds. This PRD is about the protection layer, not the bitrate ladder.
- Enabling OSCE (Opus Speech Coding Enhancement — a separate libopus 1.5 neural post-processor that opusic-c exposes via an `osce` feature flag). Valuable, complementary, and free once opusic-c is in — but out of scope here to keep the PRD focused. Track as follow-up.
- Video, audio-over-MoQ, or any protocol-layer changes discussed in prior conversations.
- Touching the wzp-web / browser client. Browser Opus is a separate codepath via WebAudio / WASM libopus and is not affected by the native FFI swap.
## Background
### How the three protection mechanisms actually differ
| | Opus inband FEC (LBRR) | RaptorQ (wzp-fec) | DRED |
|---|---|---|---|
| Layer | codec-internal | application, across Opus packets | codec-internal |
| What it sends | low-bitrate copy of the *previous* frame, embedded in every packet | fountain-code repair symbols across a block | neural-coded history of the recent past |
| Protection horizon | 1 packet back | block duration (currently 100 ms, proposed 40 ms) | configurable, 0–1040 ms |
| Recovery granularity | 1 frame (lower quality) | 1 frame (bit-exact) | 10 ms frames (plausible reconstruction) |
| Latency cost | 0 ms | block duration on receive | 0 ms |
| Bitrate cost | ~20–40% of base | `fec_ratio × base` (currently +20% GOOD, +50% DEGRADED) | ~1 kbps flat |
| Effective loss tolerance | ~single-packet losses | up to `(repair symbols / block)` losses, cliff beyond | bursts up to the configured duration |
| Content assumption | any Opus audio | any | speech (DRED model is speech-trained) |
### Why DRED dominates on the Opus tiers
Loss-scenario walkthrough (verified against opusic-c and libopus 1.5 docs):
- **1-frame loss (20 ms)**: RaptorQ recovers bit-exactly, DRED wouldn't run (classical Opus PLC is perceptually indistinguishable for single 20 ms frames). RaptorQ "wins" on paper but not on ears.
- **2–3 frame burst (40–60 ms)**: RaptorQ at current ratio 0.2 hits its tolerance cliff. DRED handles this trivially — well within a 200 ms window.
- **5–10 frame burst (100–200 ms)**: RaptorQ completely overwhelmed at any reasonable ratio. DRED's sweet spot.
- **10+ frame burst (>200 ms)**: RaptorQ useless. DRED at 500–1000 ms still recovers.
The only scenario where RaptorQ strictly beats DRED is bit-exact recovery of isolated single-frame losses — which is perceptually irrelevant for speech. In every other scenario DRED either ties or wins.
### Why Codec2 keeps RaptorQ
DRED lives inside libopus — it does not help Codec2 at all. Codec2's classical PLC is a parametric-vocoder interpolation that produces noticeably robotic artifacts on loss. On the Codec2 tiers, RaptorQ is the only protection we have, and it should stay at current ratios (1.0 on CATASTROPHIC, 0.5 on the Codec2 3200 tier).
### The opusic-c / opusic-sys situation
- `opusic-sys 0.6.0` — FFI crate, published 2026-03-17, vendors libopus 1.5.2 via its `bundled` feature (on by default), documents Android NDK cross-compile via `ANDROID_NDK_HOME` (which our `wzp-android/build.rs` already sets). Exposes raw bindings to `opus_dred_parse`, `opus_decoder_dred_decode`, and the `OpusDRED` state struct.
- `opusic-c 1.5.5` — high-level safe wrapper. Its **encoder** side is fine: exposes `Encoder::set_dred_duration(value: u8) -> Result<(), ErrorCode>` with range `0..=104` (each unit is 10 ms, so 0–1040 ms configurable). Also exposes `set_bitrate`, `set_inband_fec`, `set_dtx`, `set_packet_loss`, `set_signal`, `set_complexity`, `set_bandwidth`, `set_application` on the encoder.
- **opusic-c's decoder-side DRED wrapper is NOT sufficient for our architecture.** Confirmed by reading the source of `opusic-c/src/dred.rs`:
1. `Dred::decode_to` ignores the `dred_end` output of `opus_dred_parse` (prefixed `_dred_end`), so the caller cannot know how much DRED history a given packet actually carried.
2. In `opus_decoder_dred_decode(decoder, dred, dred_offset, pcm, frame_size)`, the wrapper passes `frame_size` to BOTH the `dred_offset` and `frame_size` arguments. This looks like a bug — it means reconstruction always starts at offset `frame_size` into the DRED window, not at an arbitrary caller-chosen offset. Arbitrary-gap reconstruction (which we need for the lookahead/backfill pattern) requires proper offset control.
3. `DredPacket` is owned internally by a `Dred` instance; its internal buffer is overwritten on every `decode_to` call. We cannot hold a ring of parsed DredPackets from multiple recent arrivals — which is exactly what the lookahead/backfill jitter buffer pattern requires.
- **Decision**: use opusic-c for the encoder path (its wrapper is correct and saves work), and drop to `opusic-sys` raw FFI for the entire decoder path AND the DRED reconstruction path. Both use a single shared `DecoderHandle` so internal decoder state stays consistent. **Verified at pre-flight**: `opusic_c::Decoder.inner` is `pub(crate)`, so there is no way to reach the raw `*mut OpusDecoder` from outside opusic-c. Running two parallel decoders (one from opusic-c for audio, one from opusic-sys for DRED) would cause state drift because the DRED-only decoder wouldn't see the normal decode calls. Single unified decoder via opusic-sys is the only correct architecture.
- **Three FFI handles required** per decode session: `opusic_c::Encoder` (encoder side, unchanged), our own `DecoderHandle` wrapping `*mut OpusDecoder` from opusic-sys (for normal decode AND for the `OpusDecoder` pointer passed to `opus_decoder_dred_decode`), and a new `DredDecoderHandle` wrapping `*mut OpusDREDDecoder` from opusic-sys (passed to `opus_dred_parse`). Note: `OpusDREDDecoder` is a **separate struct** from `OpusDecoder` in libopus 1.5 — verified from opus.h. Allocation via `opus_dred_decoder_create()` (confirm exact symbol name at Phase 3a start).
- The `opus` crate from SpaceManiac (0.3.1, published 2026-01-03) is a trap: it depends on `audiopus_sys ^0.2.0` — the same dead FFI crate we're trying to get away from. Do not use.
- **Follow-up (out of scope for this PRD)**: upstream the fixes to `opusic-c/src/dred.rs` (preserve `dred_end`, fix the `dred_offset` double-pass, expose `DredPacket` externally). Worth a GitHub PR once our own implementation has proven correct. Would let us eventually delete our internal FFI wrapper.
### Critical note from opusic-c docs
From the `dred` module documentation: *"The documentation recommends disabling in-band FEC and using `Application::Voip` for optimal results."* This applies to the **codec-internal** Opus inband FEC (LBRR), not our application-level RaptorQ. The two are independent layers. This PRD disables both on Opus tiers, but for different reasons — inband FEC per upstream recommendation, RaptorQ per the analysis above.
### The libopus 1.5 loss-percentage gating quirk
In libopus 1.5, both inband FEC and DRED are gated on `OPUS_SET_PACKET_LOSS_PERC` being non-zero. If the encoder thinks loss is 0%, it will not emit DRED data even when `set_dred_duration` is configured. We must plumb a meaningful loss percentage into the encoder continuously, floored at a small non-zero value so DRED stays active even when the network is perfect. Planned floor: **5%**, overridden upward by the real `QualityReport` loss value when it exceeds the floor.
## Solution
### High-level architecture change
**Before** (per Opus frame encode path):
```
PCM → AdaptiveEncoder.encode (Opus)
→ inband FEC embedded in packet
→ wzp-fec FEC encoder (accumulate into block, generate repair symbols)
→ DATAGRAM out
```
**Before** (per Opus frame decode path):
```
DATAGRAM in → wzp-fec block assembly (wait for block, recover if possible)
→ AdaptiveDecoder.decode (Opus) / decode_lost (classical PLC)
→ PCM
```
**After** (Opus tiers):
```
PCM → OpusEncoder.encode (opusic-c, DRED enabled via set_dred_duration, inband FEC off)
→ DATAGRAM out directly (no RaptorQ block)
```
```
DATAGRAM in → jitter buffer (lookahead/backfill)
→ on frame arrival: OpusDecoder.decode
→ on detected gap: if next packet has DRED state → dred::Dred.reconstruct(gap)
else → OpusDecoder.decode_lost (classical PLC)
→ PCM
```
**After** (Codec2 tiers): unchanged. RaptorQ block encoding + classical Codec2 decode path stay exactly as they are today.
### New per-profile protection matrix
| Profile | Codec | Inband FEC | RaptorQ ratio | DRED duration | Total overhead |
|---|---|---|---|---|---|
| `STUDIO_64K` | Opus 64k | **off** | **none** | **10 frames (100 ms)** | +1 kbps |
| `STUDIO_48K` | Opus 48k | **off** | **none** | **10 frames (100 ms)** | +1 kbps |
| `STUDIO_32K` | Opus 32k | **off** | **none** | **10 frames (100 ms)** | +1 kbps |
| `GOOD` | Opus 24k | **off** | **none** | **20 frames (200 ms)** | +1 kbps |
| `NORMAL_16K` | Opus 16k | **off** | **none** | **20 frames (200 ms)** | +1 kbps |
| `DEGRADED` | Opus 6k | **off** | **none** | **50 frames (500 ms)** | +1 kbps |
| `CODEC2_3200` | Codec2 3200 | N/A | **0.5 (unchanged)** | N/A | +50% |
| `CATASTROPHIC` | Codec2 1200 | N/A | **1.0 (unchanged)** | N/A | +100% |
| `COMFORT_NOISE` | CN | — | — | — | — |
DRED duration rationale:
- **Studio tiers (100 ms)**: loss is rare on the networks where users pick studio quality. Short DRED window keeps decode-side CPU modest. Still covers multi-frame bursts that classical PLC can't touch.
- **Normal tiers (200 ms)**: balanced baseline. Handles the common VoIP loss pattern (20–150 ms bursts from wifi roam, transient congestion).
- **Degraded tier (500 ms)**: users on Opus 6k are by definition on a bad link. Long DRED window buys maximum burst resilience where it matters most. Still well under the 1040 ms cap.
### Runtime escape hatch
Ship with a single environment variable / settings flag: **`AUDIO_USE_LEGACY_FEC`**. When set, the entire Opus-tier path reverts to the pre-PRD behavior: RaptorQ re-enabled at the old ratios, Opus inband FEC re-enabled, DRED disabled (`set_dred_duration(0)`). This is the rollback safety valve for the first production window.
Escape hatch semantics:
- Read once at `CallEncoder::new` / `CallDecoder::new` time. Call-scoped, not re-read mid-call.
- Exposed via Android Settings UI as a hidden "Legacy FEC (debug)" toggle, and as a CLI flag `--legacy-fec` on the desktop client.
- Logged in `DebugReporter` so we can tell which mode a call was in when diagnosing.
- Removed entirely after 2 months of stable production with no regressions reported. Removal is a follow-up PR, not part of this PRD's scope.
## Detailed design
### Phase 0 — FFI crate swap (prerequisite, no behavior change)
**Files touched:**
- `Cargo.toml` (workspace root) — replace `audiopus = "0.3.0-rc.0"` with `opusic-c = { version = "1.5.5", features = ["bundled", "dred"] }` and `opusic-sys = { version = "0.6.0", features = ["bundled"] }`. The `opusic-sys` direct dep is for the DRED decoder path below.
- `crates/wzp-codec/Cargo.toml` — update `audiopus = { workspace = true }` to `opusic-c = { workspace = true }`, add `opusic-sys = { workspace = true }`, add `bytemuck = "1"` for the i16↔u16 slice cast.
- `crates/wzp-codec/src/opus_enc.rs` — rewrite against opusic-c. API mapping:
- `audiopus::coder::Encoder::new(SampleRate::Hz48000, Channels::Mono, Application::Voip)` → `opusic_c::Encoder::new(Channels::Mono, SampleRate::Hz48000, Application::Voip)` (argument order swapped)
- `set_bitrate(Bitrate::BitsPerSecond(bps))` → `set_bitrate(Bitrate::Bits(bps))` or equivalent variant — verify at implementation time
- `set_inband_fec(true/false)` → `set_inband_fec(InbandFec::On/Off)` (now an enum)
- `set_packet_loss_perc(u8)` → `set_packet_loss(u8)` (method renamed)
- `set_dtx(bool)`, `set_signal(Signal::Voice)`, `set_complexity(u8)` — names match
- `encode(&[i16], &mut [u8])` → `encode_to_slice(&[u16], &mut [u8])` with `bytemuck::cast_slice::<i16, u16>(pcm)` at the call site
- `crates/wzp-codec/src/opus_dec.rs` — same-style rewrite for the `Decoder` path. Note that opusic-c's decoder methods take `decode_fec: bool` as a parameter directly (not a separate ctl).
- `vendor/audiopus_sys/` — delete the directory (only exists on `feat/desktop-audio-rewrite`, not on `android-rewrite`, so this is a no-op on the current branch but do remove the `[patch.crates-io]` block from Cargo.toml when merging back).
**Acceptance criteria:**
- `cargo check --workspace` passes on Linux x86_64, macOS, and Android NDK cross-compile.
- All existing codec unit tests in `crates/wzp-codec/src/adaptive.rs` pass unchanged. DRED is still disabled at this phase (default `set_dred_duration(0)`), so behavior is equivalent to pre-swap libopus 1.3 for call quality purposes.
- A short real-call smoke test produces audio identical to current behavior (no audible regression).
- `opusic_c::version()` at startup logs libopus version containing `1.5.2` — hard signal that the swap landed correctly.
### Phase 1 — DRED encoder enable on all Opus profiles
**Files touched:**
- `crates/wzp-codec/src/opus_enc.rs`:
- Add `fn dred_duration_for(codec: CodecId) -> u8` returning the per-profile value from the matrix above (10 / 20 / 50 frames).
- In `OpusEncoder::new`, after the existing `set_bitrate`/`set_signal`/`set_complexity` block: call `inner.set_inband_fec(InbandFec::Off)`, then `inner.set_dred_duration(dred_duration_for(profile.codec))`, then `inner.set_packet_loss(5)` as the default floor.
- Add `pub fn set_dred_duration(&mut self, frames: u8)` to allow the adaptive ladder to update DRED duration on profile switch.
- In the existing `set_profile` impl, call `set_dred_duration(dred_duration_for(profile.codec))` after `apply_bitrate`.
- `crates/wzp-codec/src/adaptive.rs`:
- `AdaptiveEncoder::set_profile` already delegates to `self.opus.set_profile` — no changes needed. DRED update rides along.
- `crates/wzp-client/src/call.rs` (and equivalent on `wzp-android/src/pipeline.rs`):
- In the `QualityReport` handler (wherever we currently call `set_expected_loss` / `set_packet_loss_perc`), also ensure the loss value is floored at 5% before passing to the Opus encoder. This is a 1-line change.
**Acceptance criteria:**
- Encoder produces DRED-enabled Opus packets. Verifiable via libopus's reference decoder in debug mode, or by wire capture + inspection — a DRED-bearing Opus packet has a larger `opus_packet_get_nb_frames` footprint than a non-DRED one of the same nominal bitrate.
- Total outgoing bitrate on Opus 24k is ~25 kbps (up from ~24 kbps) — confirms ~1 kbps DRED overhead.
- On a lossless path, decoder output is audibly identical to Phase 0.
- Escape hatch `AUDIO_USE_LEGACY_FEC=1` cleanly reverts the DRED enable (calls `set_dred_duration(0)` and `set_inband_fec(InbandFec::On)` instead).
### Phase 2 — RaptorQ removal on Opus tiers
**Files touched:**
- `crates/wzp-client/src/call.rs`:
- In `CallEncoder::encode_frame` (or wherever `wzp_fec::Encoder::add_source_symbol` is called), gate the RaptorQ path on `!profile.codec.is_opus()` — Opus frames go straight to DATAGRAM emit, Codec2 frames continue through RaptorQ.
- When a profile switch crosses the Opus↔Codec2 boundary, flush/reset the RaptorQ encoder state.
- `crates/wzp-android/src/pipeline.rs`:
- Mirror the same gate in the Android encode path.
- `crates/wzp-proto/src/packet.rs`:
- `MediaHeader.fec_block` and `fec_symbol` are still valid fields on the wire. For Opus packets we emit `fec_block = 0`, `fec_symbol = 0`, `fec_ratio_encoded = 0`. No wire format change; the receiver just sees all-zeros in the FEC fields for Opus packets and skips the FEC decoder path.
- Bump protocol version to v1 → v2? **No** — the change is semantically backward compatible because existing RaptorQ decoders handle a zero ratio correctly (ratio 0.0 means "no repair symbols expected"). Old receivers can still decode new Opus packets; they just won't see any DRED benefit because their libopus is old. This is a property we want: the opposite (new receiver, old sender) is the more common mixed-version case during rollout and also Just Works.
- `crates/wzp-client/src/call.rs` — `CallDecoder`:
- Symmetric change: Opus frames bypass the RaptorQ block assembly, go straight to the decoder. Only Codec2 frames (`codec_id.is_codec2()`) feed through `wzp-fec` block decoding.
**Acceptance criteria:**
- Outgoing Opus packets have `fec_ratio_encoded == 0` (verifiable with the existing wire capture tooling in `wzp-client/src/echo_test.rs`).
- On a clean network, receiver latency (measured as encode-to-playout one-way delay) drops by ~40 ms versus Phase 1. This is the primary win and should be directly measurable with the existing telemetry.
- Codec2 calls show no latency change and no packet-format change. Regression-test Codec2 3200 and Codec2 1200 specifically.
- Total outgoing bitrate on Opus 24k drops from ~28.8 kbps (24k base + 0.2 RaptorQ ratio) to ~25 kbps (24k base + ~1 kbps DRED). Direct savings observable in network telemetry.
### Phase 3 — DRED reconstruction wrapper + jitter buffer lookahead/backfill refactor
This phase is larger than originally estimated because opusic-c's decoder-side DRED wrapper is unusable for our architecture (see Background). We write our own safe wrapper over `opusic-sys` raw FFI first, then plumb it through the jitter buffer.
**Step 3a — Safe DRED reconstruction wrapper in `wzp-codec`:**
New file `crates/wzp-codec/src/dred_ffi.rs`. Wraps the raw libopus 1.5 DRED API:
- `pub struct DredState` — owns an `OpusDRED` buffer (allocated via `opusic_sys::opus_dred_alloc` or equivalent; size is fixed at 10,592 bytes per libopus 1.5). `Clone` is intentionally NOT implemented — the state is heap-owned and non-trivial to copy.
- `pub fn parse_from_packet(&mut self, decoder: &opusic_c::Decoder, packet: &[u8], max_dred_samples: i32) -> Result<DredParseResult, DredError>` — wraps `opus_dred_parse`, preserves the `dred_end` output (number of samples of history the packet carried), returns it in `DredParseResult { samples_available: i32, frames_available: u8 }`.
- `pub fn reconstruct_into(&self, decoder: &mut opusic_c::Decoder, dred_offset_samples: i32, output: &mut [i16]) -> Result<usize, DredError>` — wraps `opus_decoder_dred_decode`, takes the offset explicitly, decodes `output.len()` samples starting from that offset in the DRED window.
- All `unsafe` contained here, strict bounds checking on offsets, Rust-level panic safety. Unit tests use a reference encoder + known-good reference decoder to verify that reconstruction at specific offsets produces expected output.
- Depends on `opusic-sys` directly and on `opusic-c::Decoder` for the decoder handle. The Decoder handle must be reachable as a raw pointer; opusic-c exposes this via an unstable internal or we wrap the pointer ourselves. **Verify at implementation time** — if opusic-c doesn't expose the raw decoder pointer safely, we create our own thin Decoder wrapper in `dred_ffi.rs` using raw opusic-sys, losing the convenience of opusic-c's decoder but keeping its encoder. This is the smaller-risk fallback.
New `pub trait DredReconstructor` in `wzp-codec/src/lib.rs`:
```rust
pub trait DredReconstructor: Send {
/// Parse DRED state from an arriving Opus packet into `state`.
/// Returns number of 48 kHz samples of history available, or 0 if the packet has no DRED.
fn parse(&mut self, state: &mut DredState, packet: &[u8]) -> Result<i32, DredError>;
/// Reconstruct `output.len()` samples from `state`, starting at the given
/// sample offset (measured from the end of the DRED window going backward).
fn reconstruct(&mut self, state: &DredState, offset_samples: i32, output: &mut [i16]) -> Result<usize, DredError>;
}
```
Implement `DredReconstructor` over the `dred_ffi::DredState` + opusic-c Decoder combination. This is the clean boundary the jitter buffer will talk to.
**Step 3b — Jitter buffer refactor in `crates/wzp-transport/src/jitter.rs`:**
- Current behavior: buffer waits a fixed number of frames of jitter before emitting; on a missing slot, after a timeout it gives up and signals the decoder to run `decode_lost()` (classical Opus PLC or Codec2 PLC).
- New behavior on Opus tiers: when a frame arrives (in-order or late), first call `DredReconstructor::parse` on it to update a rolling ring of `DredState` instances tagged with their originating sequence number. When a gap is detected (missing sequence number between last-emitted and current arrival), and the ring contains a `DredState` from a nearby packet that covers the gap's sample offset, call `DredReconstructor::reconstruct` with the correct offset to synthesize the missing frames, splice them into playout, then continue normal decode.
- If no DRED state covers the gap (e.g., gap too far back, or every nearby packet was dropped), fall through to classical PLC exactly as today. The classical path stays intact as the ultimate fallback.
- Codec2 packets bypass the entire DRED ring. They are not inspected for DRED state and take the unchanged classical PLC path.
- Ring sizing: `max_dred_duration_frames` + `jitter_depth_frames` worth of `DredState` instances. At 500 ms DRED on degraded tier + 60 ms jitter depth, that's ~28 DredState instances × 10,592 bytes ≈ 300 KB. Acceptable. On studio tier with 100 ms DRED it's only ~80 KB.
- The jitter buffer takes a `Box<dyn DredReconstructor>` at construction, passed in by the call engine. `wzp-transport` does NOT take a direct dep on `opusic-c` or `opusic-sys` — it only knows about the trait defined in `wzp-codec`.
**Files touched:**
- `crates/wzp-codec/src/dred_ffi.rs` (new, ~150–300 lines)
- `crates/wzp-codec/src/lib.rs` — expose `DredReconstructor`, `DredState`, `DredError` types
- `crates/wzp-codec/Cargo.toml` — add `opusic-sys = { workspace = true }` as a direct dep (already done in Phase 0)
- `crates/wzp-transport/src/jitter.rs` — lookahead/backfill refactor, DRED ring
- `crates/wzp-transport/Cargo.toml` — add `wzp-codec = { workspace = true }` (likely already present) for the trait import
- `crates/wzp-client/src/call.rs` — construct a `DredReconstructor` and pass into `CallDecoder`'s jitter buffer
- `crates/wzp-android/src/pipeline.rs` — same on Android
**Acceptance criteria:**
- Unit tests in `dred_ffi.rs`: round-trip a known speech waveform through an encoder with DRED enabled, parse the resulting packets, reconstruct at several different offsets, verify the reconstructed samples are within an energy/spectral threshold of the original. (Not bit-exact — DRED reconstruction is lossy by design.)
- Synthetic loss test on the full pipeline: inject 200 ms bursts at 10% rate into a looped call, verify the DRED reconstruction rate on receiver telemetry is ≥95% of all loss events whose gaps fall within the configured DRED duration window.
- Reconstructed audio is audibly continuous on 40–200 ms bursts — no gaps, no classical-PLC robot artifact. Verified on real voice samples (not just sine tones), and on at least two distinct speaker profiles (male, female) because DRED can have voice-dependent quality.
- End-to-end latency metric is unchanged versus Phase 2 (no regression from adding the lookahead path). The DRED ring insertion on packet arrival must be O(1) in practice.
- Existing `echo_test.rs` and `drift_test.rs` pass with the new jitter buffer.
- Codec2 path uses classical PLC exclusively (no DRED invocation) because Codec2 packets don't carry DRED state. Verify by injecting loss on a Codec2 call and confirming zero DRED reconstruction telemetry events during that call.
- `wzp-transport` has no direct dependency on `opusic-sys` or `opusic-c` in its `Cargo.toml` after the refactor — only on `wzp-codec`. Verify by grepping the Cargo.toml file.
### Phase 4 — Telemetry and tooling updates
**Files touched:**
- `crates/wzp-proto/src/packet.rs` — `QualityReport` or equivalent telemetry message gains `dred_reconstructions: u32` as a new counter (frames reconstructed via DRED this reporting window) and `classical_plc_invocations: u32` (frames filled by Opus/Codec2 classical PLC). These are separate counters because they're different recovery mechanisms.
- `crates/wzp-relay/src/*` — relay telemetry pipeline surfaces both counters in Prometheus metrics: `wzp_dred_reconstructions_total{call_id}`, `wzp_classical_plc_total{call_id}`.
- `docs/grafana-dashboard.json` — new panel: "Loss recovery breakdown" stacked bar, DRED vs classical PLC vs clean decode, per call.
- `android/app/src/main/java/com/wzp/debug/DebugReporter.kt` — surfaces `dredReconstructions` and `classicalPlc` counts in the debug report; also logs active DRED duration and whether legacy-FEC mode is engaged.
**Acceptance criteria:**
- Grafana dashboard shows a clear visual distinction between DRED-recovered and classical-PLC-recovered frames across a test fleet of calls.
- Debug report includes the active protection mode ("DRED 200 ms" / "Legacy RaptorQ") and reconstruction counts, so incidents can be classified unambiguously.
### Phase 5 — Escape hatch removal (follow-up, ~2 months post-ship)
After 2 months of stable production with no rollbacks triggered:
- Delete `AUDIO_USE_LEGACY_FEC` handling in `opus_enc.rs` / `call.rs` / `pipeline.rs`
- Delete the Opus-tier paths of `wzp-fec` (the crate stays for Codec2)
- Delete the Android settings toggle and desktop CLI flag
- Remove the `--legacy-fec` path from smoke tests
## Critical files to modify (summary)
- `Cargo.toml` (workspace) — dep swap (audiopus → opusic-c + opusic-sys)
- `crates/wzp-codec/Cargo.toml` — dep swap + `bytemuck` for slice cast
- `crates/wzp-codec/src/opus_enc.rs` — opusic-c rewrite + DRED enable + inband FEC off
- `crates/wzp-codec/src/opus_dec.rs` — opusic-c rewrite
- `crates/wzp-codec/src/dred_ffi.rs` — **new file**, safe wrapper over opusic-sys raw DRED FFI
- `crates/wzp-codec/src/lib.rs` — expose `DredReconstructor` trait, `DredState`, `DredError`
- `crates/wzp-codec/src/adaptive.rs` — verify profile switch carries DRED duration
- `crates/wzp-client/src/call.rs` — Opus/Codec2 gate on RaptorQ path, loss floor, wire DredReconstructor into CallDecoder
- `crates/wzp-android/src/pipeline.rs` — same gate, same loss floor, wire DredReconstructor
- `crates/wzp-transport/src/jitter.rs` — lookahead/backfill refactor, DRED ring, reconstruction dispatch
- `crates/wzp-transport/Cargo.toml` — verify it depends only on `wzp-codec`, not directly on opusic-*
- `crates/wzp-proto/src/packet.rs` — new telemetry counters
- `crates/wzp-relay/` — Prometheus metric exposure
- `android/app/src/main/java/com/wzp/debug/DebugReporter.kt` — debug output
- `docs/grafana-dashboard.json` — loss-recovery panel
- (delete) `vendor/audiopus_sys/` on `feat/desktop-audio-rewrite` when merging back
## Existing utilities to reuse
- `wzp_codec::resample::Downsampler48to8` / `Upsampler8to48` — unchanged, only Codec2 path uses them
- `wzp_codec::adaptive::AdaptiveEncoder` / `AdaptiveDecoder` — existing profile-switching machinery, DRED duration changes ride along
- `wzp_codec::silence::SilenceDetector` / `ComfortNoise` — unchanged
- `wzp_codec::agc::AutoGainControl` — unchanged, runs before encode as today
- `wzp_fec::RaptorQFecEncoder` / decoder — unchanged, still used for Codec2 tiers
- `wzp_client::call::QualityAdapter` — unchanged; drives profile switching, which now also reconfigures DRED duration via the existing `set_profile` path
## Verification
End-to-end testing, in order:
1. **Unit**: `cargo test -p wzp-codec` — Opus encode/decode round-trip at every profile, DRED enabled. Verify `version()` reports libopus 1.5.2.
2. **Unit**: `cargo test -p wzp-transport` — jitter buffer lookahead/backfill behavior with injected loss patterns (0%, 5%, 15%, 30%, 50% loss; isolated losses, 40 ms bursts, 200 ms bursts, 500 ms bursts).
3. **Integration**: `crates/wzp-client/src/echo_test.rs` — existing echo test must pass on all Opus profiles with <5% perceived quality regression (measure via the time-window analysis already built into `echo_test.rs`).
4. **Integration**: `crates/wzp-client/src/drift_test.rs` — latency measurement. Must show ~40 ms reduction on Opus profiles versus pre-PRD baseline. Codec2 profiles unchanged.
5. **Manual**: Android release build, real call over bad wifi (or a shaped network via `tc netem` on Linux). Burst losses of 200 ms should be perceptually continuous speech, not robotic gaps.
6. **Manual**: Same call with `AUDIO_USE_LEGACY_FEC=1` — verify behavior reverts to current production behavior. This is the pre-ship rollback rehearsal.
7. **Cross-compile**: full build matrix — Android arm64-v8a + armeabi-v7a (via `scripts/build-and-notify.sh`), macOS universal, Linux x86_64 (via `scripts/build-linux-docker.sh`). Windows cross-compile via cargo-xwin should also pass — libopus 1.5 upstream fixed the clang-cl SIMD issue that required the vendor patch on `feat/desktop-audio-rewrite`.
8. **Telemetry smoke**: deploy to staging relay, make 10 test calls, verify Grafana's new "Loss recovery breakdown" panel shows DRED reconstruction events firing on injected loss and classical-PLC on packet-loss beyond DRED's window.
## Risks and mitigations
- **Custom DRED FFI wrapper is WZP-maintained code with no second source.** opusic-c's decoder-side DRED wrapper is insufficient (see Background), so we carry our own `dred_ffi.rs` that calls `opus_dred_parse` and `opus_decoder_dred_decode` directly via opusic-sys. Bugs in this wrapper — offset arithmetic off-by-ones, lifetime errors on `OpusDRED` buffers, UB from misuse of the C API — could manifest as silent audio corruption on loss bursts, hard to diagnose. **Mitigation**: extensive unit tests in `dred_ffi.rs` using a reference encoder + reference decoder round-trip with known offsets; strict bounds checking on every `unsafe` boundary; Miri run in CI if feasible; the legacy-FEC escape hatch disables the entire DRED code path including our custom wrapper, giving us a single flag to revert any wrapper bug in production. Long-term: upstream the fixes to opusic-c (follow-up task, not blocking).
- **opusic-c's encoder-side API and internal Decoder pointer access**. Step 3a depends on being able to call opusic-sys raw functions that take an `*mut OpusDecoder` pointer while still using opusic-c's `Decoder` for normal decode. If opusic-c doesn't expose the raw pointer cleanly, we fall back to a thin opusic-sys-direct Decoder wrapper inside `dred_ffi.rs` and lose some of opusic-c's convenience. **Mitigation**: verify at the start of Phase 3 (one afternoon of reading opusic-c source). If the clean path doesn't work, the fallback is not difficult — it's what we'd have built anyway if opusic-c didn't exist.
- **DRED reconstruction quality varies by voice / content**. The neural model is trained on speech; edge cases (shouting, whispering, heavy accents, music-on-hold, cough, laughter) may reconstruct less cleanly than continuous speech. **Mitigation**: escape hatch ships from day one. If production telemetry shows perceptible quality regression on specific voice patterns, flip legacy mode for affected users while tuning. Also: classical Opus PLC remains as the third-tier fallback when DRED state is unavailable.
- **Removing RaptorQ removes bit-exact recovery**. Isolated single-packet losses are now reconstructed plausibly instead of bit-exactly. **Mitigation**: as argued in Background, bit-exactness on a single 20 ms speech frame is perceptually meaningless. The assumption is "speech is the workload" — if we ever add non-speech features (music bot, ringtones over the call path, DTMF-over-audio) we revisit.
- **libopus 1.5 DRED API stability**. **Verified at pre-flight**: opus.h in the upstream xiph/opus repository has no "experimental" marker on the DRED API declarations. The earlier characterization was incorrect. DRED shipped as a first-class feature in libopus 1.5.0 (Dec 2023) and has been iterated in 1.5.1 and 1.5.2. Google Meet and Duo ship it at scale. **Mitigation**: pin `opusic-sys` exactly (no `^` range) to ensure reproducible builds, follow upstream 1.5.x bugfixes as they land. No special stability concerns beyond normal dependency hygiene.
- **Jitter buffer refactor is the largest code change**. Jitter bugs are notoriously subtle (off-by-one on sequence wraparound, clock drift interactions, playout starvation corner cases). **Mitigation**: keep the classical-PLC path intact as the DRED fallback, so jitter bugs degrade to "current behavior" rather than "broken audio". Write targeted unit tests for the buffer at each loss-pattern scenario before touching production paths. Consider shipping Phase 3 behind a sub-flag separate from the main escape hatch, so we can independently toggle "DRED enabled but classical jitter buffer" for bisection.
- **Cross-compile surprises**. `opusic-sys` is actively maintained but our exact combination of Android NDK version / Docker builder environment / Windows cross-compile via cargo-xwin has not been tested by upstream. **Mitigation**: Phase 0 includes the full cross-compile matrix as an acceptance criterion. Any blockers surface before we touch loss-recovery behavior.
- **Wire-format compatibility during rollout**. Mixed-version calls (new sender + old receiver, or vice versa) need to keep working. **Verified at pre-flight**: traced both live receive paths (`wzp-client/src/call.rs::CallDecoder::ingest` and `wzp-android/src/engine.rs` the JNI-driven engine path), and both degrade gracefully: new-sender Opus packets with `fec_ratio_encoded=0` / `fec_block=0` / `fec_symbol=0` flow through to the jitter buffer and decode normally on old receivers. The RaptorQ decoder either ignores zero-FEC packets entirely (Android pipeline.rs gates on non-zero fec_block/fec_symbol) or accumulates them harmlessly until the 2-second staleness eviction (desktop call.rs). Old-sender packets with populated RaptorQ fields are handled by new receivers via the unchanged Codec2 path (new receivers keep wzp-fec for Codec2 tiers and simply ignore RaptorQ fields on Opus packets). **No wire format version bump required.**
- **Pre-existing desktop RaptorQ gap** (incidental finding, NOT caused by this PRD). The desktop `wzp-client/src/call.rs::CallDecoder` feeds packets into `fec_dec.add_symbol` but **never calls `fec_dec.try_decode`** — RaptorQ recovery is effectively dead code on the desktop path today. Main decode reads from the jitter buffer directly, falling through to classical Opus PLC on missing packets. The Android `engine.rs` path properly uses `try_decode` for recovery. This PRD does not fix the desktop gap — it's unrelated — but is noted here so nobody is surprised that removing RaptorQ from Opus tiers on the desktop client causes no measurable recovery regression (there was nothing to lose). Recommend filing a follow-up task to either fix or remove the vestigial desktop RaptorQ wiring independently of this work.
- **`AUDIO_USE_LEGACY_FEC` itself becoming permanent tech debt**. Escape hatches have a way of outliving their intended lifespan. **Mitigation**: put an explicit removal date in a `// TODO(2026-06-15): remove legacy FEC path` comment at the flag-handling site. Track in taskmaster.
## Open questions
- ~~**Does opusic-c expose `opusic_c::Decoder`'s raw inner pointer?**~~ **Resolved at pre-flight**: no, it's `pub(crate)`. We build a unified `DecoderHandle` over raw opusic-sys in `dred_ffi.rs` and use it for both normal decode and DRED reconstruction. Opusic-c is used only for the encoder side.
- **Exact opusic-sys symbol name for DRED decoder allocation**. opus.h documents the `OpusDREDDecoder` type and `opus_dred_parse`/`opus_decoder_dred_decode` functions, but the allocation function name is not in the fetched snippet. Expected to be `opus_dred_decoder_create` / `opus_dred_decoder_destroy` per libopus naming convention, but confirm at the very start of Phase 3a by reading the actual opusic-sys bindings. If the function is not exported by opusic-sys, we file a PR upstream to opusic-sys (small fix, trivially mergeable) and temporarily vendor the function declaration locally.
- **Should the 5% loss floor be configurable per profile?** Currently specified as a constant. A future refinement might make it higher at degraded tiers and lower at studio tiers, but without real telemetry we don't know if the constant is wrong. Keep as a constant for now, revisit after 1 month of production data.
- **OSCE enable**: opusic-c has an `osce` feature flag for Opus Speech Coding Enhancement, a separate libopus 1.5 neural post-processor. Out of scope for this PRD but should be the next audio-quality follow-up. Probably one-line enable once opusic-c is in.
- **Upstream PR to opusic-c**: our own `dred_ffi.rs` wrapper should be proven in production first, then the fixes upstreamed to `opusic-c/src/dred.rs` (preserve `dred_end`, fix `dred_offset` double-pass, expose `DredPacket` externally). Follow-up task, not blocking this PRD.
- **`feat/desktop-audio-rewrite` merge**: the vendored `audiopus_sys` patch on that branch becomes obsolete under this PRD. Coordinate removal with whoever owns that branch.

# Contributing
Everyone is welcome to get involved, may it be a pull request, suggestion, bug
report, or a textual improvement! : )
The language applied in this repository is British English.
## Contributions
Contributions to `audiopus_sys` should be first discussed up via an issue and then
implemented via pull request.
Issues display development-plans or required brainstorming, feel free to ask,
suggest, and discuss!
The `master`-branch contains the latest release.
## Comments & Documentation Style
- Comments are placed the lines before the related code line, not on the same
line.
- Write full sentences in British English.
- `unsafe` must always be reasoned and their soundness must be proven via a
comment.
- Use Rust intra-doc-links paths to refer Rust items in documentation:
`[name](crate::module::struct::method)`.
- If code ends up difficult, try to simplify it, if unavoidable, explain code
with comments. Prefer explicit variable naming instead of abbreviations.
## Commit Style
Write full sentences in British English.
Commits should describe the action being peformed.
Example:
- *Fix deadlock for events.*
- *Correct grammar in `command`-example.*
## Pull Request Checklist
- Make sure to open an issue prior working on a problem or ask on existing
issue be assigned.
- If a pull requests breaks the current API, use the `breaking-changes`-branch,
otherwise `stable-changes`.
- Commits shall be as small as possible, compile, and pass all tests.
- Make sure your code is formatted with `rustfmt` and free of lints,
run `cargo fmt` and `cargo clippy`.
- If you fixed a bug, add a test for that bug. Unit tests belong inside the
same file's `mod` named `tests`, integrational tests belong inside the
`tests`-folder.
- Last but not least, make sure your planned pull request merges cleanly,
if it does not, rebase your changes.
If you have any questions left, please reach out via the issue system : )

# About
`audiopus_sys` is an FFI-Rust-binding to [`Opus`] version 1.3.
Orginally, this sys-crate was made to empower the [`serenity`]-crate to build audio features on Windows, Linux, and Mac. However, it's not limited to that.
Everyone is welcome to contribute,
check out the [`CONTRIBUTING.md`](CONTRIBUTING.md) for further guidance.
# Building
## Requirements
If you want to build Opus, you will need `cmake`.
If you have `pkg-config`, it will attempt to use that before building.
You can also link a pre-installed Opus, see [**Pre-installed Opus**](#Pre-installed-Opus)
below.
This crate provides a pre-built binding. In case you want to generate the
binding yourself, you will need [`Clang`](https://rust-lang.github.io/rust-bindgen/requirements.html#clang),
see [**Pre-installed Opus**](#Generating-The-Binding) below for further
instructions.
## Linking
`audiopus_sys` links to Opus 1.3 and supports Windows, Linux, and MacOS
By default, we statically link to Windows, MacOS, and if you use the
`musl`-environment. We will link dynamically for Linux except when using
mentioned `musl`.
This can be altered by compiling with the `static` or `dynamic` feature having
effects respective to their names. If both features are enabled,
we will pick your system's default.
Environment variables named `LIBOPUS_STATIC` or `OPUS_STATIC` will take
precedence over features thus overriding the behaviour. The value of these
environment variables have no influence of the result: If one of them is set,
statically linking will be picked.
## Pkg-Config
By default, `audiopus_sys` will use `pkg-config` on Unix or GNU.
Setting the environment variable `LIBOPUS_NO_PKG` or `OPUS_NO_PKG` will bypass
probing for Opus via `pkg-config`.
## Pre-installed Opus
If you have Opus pre-installed, you can set `LIBOPUS_LIB_DIR` or
`OPUS_LIB_DIR` to the directory containing Opus.
Be aware that using an Opus other than version 1.3 may not work.
# Generating The Binding
If you want to generate the binding yourself, you can use the
`generate_binding`-feature.
Be aware, `bindgen` requires Clang and its `LIBCLANG_PATH`
environment variable to be specified.
# Installation
Add this to your `Cargo.toml`:
```toml
[dependencies]
audiopus_sys = "0.2"
```

# WZP: distinguish real cl.exe from clang-cl. libopus uses `if(NOT MSVC)`
# to guard per-file `-msse4.1` / `-mssse3` / `-msse2` flags that GCC and
# clang (GNU driver) accept. Under clang-cl (Clang running in MSVC driver
# mode, as used by cargo-xwin cross-compiles), CMake sets MSVC=1 via
# Platform/Windows-MSVC.cmake, so those guards become false and the
# SIMD source files end up compiled WITHOUT the required target feature
# — which then explodes in silk/x86/NSQ_sse4_1.c with
# "always_inline function '_mm_cvtepi16_epi32' requires target feature
# 'sse4.1'" errors. clang-cl, unlike real cl.exe, still honors Clang's
# target-feature system, and accepts `-msse4.1` (LLVM 14+) to enable it.
#
# Split real cl.exe (which genuinely doesn't need per-feature gating
# because its SIMD intrinsic headers are unconditionally available) from
# clang-cl (which does need gating) using CMAKE_C_COMPILER_ID. Then the
# `if(NOT MSVC)` guards below become `if(NOT MSVC_CL)` so clang-cl gets
# the GCC-style per-file flags, and the `if(MSVC)` global /arch block at
# the bottom becomes `if(MSVC_CL)` so only real cl.exe applies `/arch:AVX`
# / `/arch:SSE2` globally (clang-cl relies on per-file `-msse` instead).

== Opus audio codec ==
Opus is a codec for interactive speech and audio transmission over the Internet.
Opus can handle a wide range of interactive audio applications, including
Voice over IP, videoconferencing, in-game chat, and even remote live music
performances. It can scale from low bit-rate narrowband speech to very high
quality stereo music.
Opus, when coupled with an appropriate container format, is also suitable
for non-realtime stored-file applications such as music distribution, game
soundtracks, portable music players, jukeboxes, and other applications that
have historically used high latency formats such as MP3, AAC, or Vorbis.
Opus is specified by IETF RFC 6716:
https://tools.ietf.org/html/rfc6716
The Opus format and this implementation of it are subject to the royalty-
free patent and copyright licenses specified in the file COPYING.
This package implements a shared library for encoding and decoding raw Opus
bitstreams. Raw Opus bitstreams should be used over RTP according to
https://tools.ietf.org/html/rfc7587
The package also includes a number of test tools used for testing the
correct operation of the library. The bitstreams read/written by these
tools should not be used for Opus file distribution: They include
additional debugging data and cannot support seeking.
Opus stored in files should use the Ogg encapsulation for Opus which is
described at:
https://tools.ietf.org/html/rfc7845
An opus-tools package is available which provides encoding and decoding of
Ogg encapsulated Opus files and includes a number of useful features.
Opus-tools can be found at:
https://gitlab.xiph.org/xiph/opus-tools.git
or on the main Opus website:
https://opus-codec.org/
== Compiling libopus ==
To build from a distribution tarball, you only need to do the following:
% ./configure
% make
To build from the git repository, the following steps are necessary:
0) Set up a development environment:
On an Ubuntu or Debian family Linux distribution:
% sudo apt-get install git autoconf automake libtool gcc make
On a Fedora/Redhat based Linux:
% sudo dnf install git autoconf automake libtool gcc make
Or for older Redhat/Centos Linux releases:
% sudo yum install git autoconf automake libtool gcc make
On Apple macOS, install Xcode and brew.sh, then in the Terminal enter:
% brew install autoconf automake libtool
1) Clone the repository:
% git clone https://gitlab.xiph.org/xiph/opus.git
% cd opus
2) Compiling the source
% ./autogen.sh
% ./configure
% make
3) Install the codec libraries (optional)
% sudo make install
Once you have compiled the codec, there will be a opus_demo executable
in the top directory.
Usage: opus_demo [-e] <application> <sampling rate (Hz)> <channels (1/2)>
<bits per second> [options] <input> <output>
opus_demo -d <sampling rate (Hz)> <channels (1/2)> [options]
<input> <output>
mode: voip | audio | restricted-lowdelay
options:
-e : only runs the encoder (output the bit-stream)
-d : only runs the decoder (reads the bit-stream as input)
-cbr : enable constant bitrate; default: variable bitrate
-cvbr : enable constrained variable bitrate; default:
unconstrained
-bandwidth <NB|MB|WB|SWB|FB>
: audio bandwidth (from narrowband to fullband);
default: sampling rate
-framesize <2.5|5|10|20|40|60>
: frame size in ms; default: 20
-max_payload <bytes>
: maximum payload size in bytes, default: 1024
-complexity <comp>
: complexity, 0 (lowest) ... 10 (highest); default: 10
-inbandfec : enable SILK inband FEC
-forcemono : force mono encoding, even for stereo input
-dtx : enable SILK DTX
-loss <perc> : simulate packet loss, in percent (0-100); default: 0
input and output are little-endian signed 16-bit PCM files or opus
bitstreams with simple opus_demo proprietary framing.
== Testing ==
This package includes a collection of automated unit and system tests
which SHOULD be run after compiling the package especially the first
time it is run on a new platform.
To run the integrated tests:
% make check
There is also collection of standard test vectors which are not
included in this package for size reasons but can be obtained from:
https://opus-codec.org/docs/opus_testvectors-rfc8251.tar.gz
To run compare the code to these test vectors:
% curl -OL https://opus-codec.org/docs/opus_testvectors-rfc8251.tar.gz
% tar -zxf opus_testvectors-rfc8251.tar.gz
% ./tests/run_vectors.sh ./ opus_newvectors 48000
== Portability notes ==
This implementation uses floating-point by default but can be compiled to
use only fixed-point arithmetic by setting --enable-fixed-point (if using
autoconf) or by defining the FIXED_POINT macro (if building manually).
The fixed point implementation has somewhat lower audio quality and is
slower on platforms with fast FPUs, it is normally only used in embedded
environments.
The implementation can be compiled with either a C89 or a C99 compiler.
While it does not rely on any _undefined behavior_ as defined by C89 or
C99, it relies on common _implementation-defined behavior_ for two's
complement architectures:
o Right shifts of negative values are consistent with two's
complement arithmetic, so that a>>b is equivalent to
floor(a/(2^b)),
o For conversion to a signed integer of N bits, the value is reduced
modulo 2^N to be within range of the type,
o The result of integer division of a negative value is truncated
towards zero, and
o The compiler provides a 64-bit integer type (a C99 requirement
which is supported by most C89 compilers).

To build this source code, simply type:
% make
If this does not work, or if you want to change the default configuration
(e.g., to compile for a fixed-point architecture), simply edit the options
in the Makefile.
An up-to-date implementation conforming to this standard is available in a
Git repository at https://gitlab.xiph.org/xiph/opus.git or on a website at:
https://opus-codec.org/
However, although that implementation is expected to remain conformant
with the standard, it is the code in this RFC that shall remain normative.
To build from the git repository instead of using this RFC, follow these
steps:
1) Clone the repository (latest implementation of this standard at the time
of publication)
% git clone https://gitlab.xiph.org/xiph/opus.git
% cd opus
2) Compile
% ./autogen.sh
% ./configure
% make
Once you have compiled the codec, there will be a opus_demo executable in
the top directory.
Usage: opus_demo [-e] <application> <sampling rate (Hz)> <channels (1/2)>
<bits per second> [options] <input> <output>
opus_demo -d <sampling rate (Hz)> <channels (1/2)> [options]
<input> <output>
mode: voip | audio | restricted-lowdelay
options:
-e : only runs the encoder (output the bit-stream)
-d : only runs the decoder (reads the bit-stream as input)
-cbr : enable constant bitrate; default: variable bitrate
-cvbr : enable constrained variable bitrate; default: unconstrained

-inbandfec : enable SILK inband FEC
-forcemono : force mono encoding, even for stereo input
-dtx : enable SILK DTX
-loss <perc> : simulate packet loss, in percent (0-100); default: 0

/*Although derived separately, the pulse vector coding scheme is equivalent to
a Pyramid Vector Quantizer \cite{Fis86}.
Some additional notes about an early version appear at
https://people.xiph.org/~tterribe/notes/cwrs.html, but the codebook ordering
and the definitions of some terms have evolved since that was written.
The conversion from a pulse vector to an integer index (encoding) and back
(decoding) is governed by two related functions, V(N,K) and U(N,K).
V(N,K) = the number of combinations, with replacement, of N items, taken K
at a time, when a sign bit is added to each item taken at least once (i.e.,
the number of N-dimensional unit pulse vectors with K pulses).
One way to compute this is via
V(N,K) = K>0 ? sum(k=1...K,2**k*choose(N,k)*choose(K-1,k-1)) : 1,
where choose() is the binomial function.
A table of values for N<10 and K<10 looks like:
V[10][10] = {
{1, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{1, 2, 2, 2, 2, 2, 2, 2, 2, 2},
{1, 4, 8, 12, 16, 20, 24, 28, 32, 36},
{1, 6, 18, 38, 66, 102, 146, 198, 258, 326},
{1, 8, 32, 88, 192, 360, 608, 952, 1408, 1992},
{1, 10, 50, 170, 450, 1002, 1970, 3530, 5890, 9290},
{1, 12, 72, 292, 912, 2364, 5336, 10836, 20256, 35436},
{1, 14, 98, 462, 1666, 4942, 12642, 28814, 59906, 115598},
{1, 16, 128, 688, 2816, 9424, 27008, 68464, 157184, 332688},
{1, 18, 162, 978, 4482, 16722, 53154, 148626, 374274, 864146}
};
U(N,K) = the number of such combinations wherein N-1 objects are taken at
most K-1 at a time.
This is given by
U(N,K) = sum(k=0...K-1,V(N-1,k))
= K>0 ? (V(N-1,K-1) + V(N,K-1))/2 : 0.
The latter expression also makes clear that U(N,K) is half the number of such
combinations wherein the first object is taken at least once.
Although it may not be clear from either of these definitions, U(N,K) is the
natural function to work with when enumerating the pulse vector codebooks,
not V(N,K).
U(N,K) is not well-defined for N=0, but with the extension
U(0,K) = K>0 ? 0 : 1,
the function becomes symmetric: U(N,K) = U(K,N), with a similar table:
U[10][10] = {
{1, 0, 0, 0, 0, 0, 0, 0, 0, 0},
{0, 1, 1, 1, 1, 1, 1, 1, 1, 1},
{0, 1, 3, 5, 7, 9, 11, 13, 15, 17},
{0, 1, 5, 13, 25, 41, 61, 85, 113, 145},
{0, 1, 7, 25, 63, 129, 231, 377, 575, 833},
{0, 1, 9, 41, 129, 321, 681, 1289, 2241, 3649},
{0, 1, 11, 61, 231, 681, 1683, 3653, 7183, 13073},
{0, 1, 13, 85, 377, 1289, 3653, 8989, 19825, 40081},
{0, 1, 15, 113, 575, 2241, 7183, 19825, 48639, 108545},
{0, 1, 17, 145, 833, 3649, 13073, 40081, 108545, 265729}
};
With this extension, V(N,K) may be written in terms of U(N,K):
V(N,K) = U(N,K) + U(N,K+1)
for all N>=0, K>=0.
Thus U(N,K+1) represents the number of combinations where the first element
is positive or zero, and U(N,K) represents the number of combinations where
it is negative.
With a large enough table of U(N,K) values, we could write O(N) encoding
and O(min(N*log(K),N+K)) decoding routines, but such a table would be
prohibitively large for small embedded devices (K may be as large as 32767
for small N, and N may be as large as 200).
Both functions obey the same recurrence relation:
V(N,K) = V(N-1,K) + V(N,K-1) + V(N-1,K-1),
U(N,K) = U(N-1,K) + U(N,K-1) + U(N-1,K-1),
for all N>0, K>0, with different initial conditions at N=0 or K=0.
This allows us to construct a row of one of the tables above given the
previous row or the next row.
Thus we can derive O(NK) encoding and decoding routines with O(K) memory
using only addition and subtraction.
When encoding, we build up from the U(2,K) row and work our way forwards.
When decoding, we need to start at the U(N,K) row and work our way backwards,
which requires a means of computing U(N,K).
U(N,K) may be computed from two previous values with the same N:
U(N,K) = ((2*N-1)*U(N,K-1) - U(N,K-2))/(K-1) + U(N,K-2)
for all N>1, and since U(N,K) is symmetric, a similar relation holds for two
previous values with the same K:
U(N,K>1) = ((2*K-1)*U(N-1,K) - U(N-2,K))/(N-1) + U(N-2,K)
for all K>1.
This allows us to construct an arbitrary row of the U(N,K) table by starting
with the first two values, which are constants.
This saves roughly 2/3 the work in our O(NK) decoding routine, but costs O(K)
multiplications.
Similar relations can be derived for V(N,K), but are not used here.
For N>0 and K>0, U(N,K) and V(N,K) take on the form of an (N-1)-degree
polynomial for fixed N.
The first few are
U(1,K) = 1,
U(2,K) = 2*K-1,
U(3,K) = (2*K-2)*K+1,
U(4,K) = (((4*K-6)*K+8)*K-3)/3,
U(5,K) = ((((2*K-4)*K+10)*K-8)*K+3)/3,
and
V(1,K) = 2,
V(2,K) = 4*K,
V(3,K) = 4*K*K+2,
V(4,K) = 8*(K*K+2)*K/3,
V(5,K) = ((4*K*K+20)*K*K+6)/3,
for all K>0.
This allows us to derive O(N) encoding and O(N*log(K)) decoding routines for
small N (and indeed decoding is also O(N) for N<3).

K=I-1 pulses fit in 32 bits.
The largest band size in an Opus Custom mode is 208.
Otherwise, we can limit things to the set of N which can be achieved by
splitting a band from a standard Opus mode: 176, 144, 96, 88, 72, 64, 48,
44, 36, 32, 24, 22, 18, 16, 8, 4, 2).*/

/*A range decoder.
This is an entropy decoder based upon \cite{Mar79}, which is itself a
rediscovery of the FIFO arithmetic code introduced by \cite{Pas76}.
It is very similar to arithmetic encoding, except that encoding is done with
digits in any base, instead of with bits, and so it is faster when using
larger bases (i.e.: a byte).
The author claims an average waste of $\frac{1}{2}\log_b(2b)$ bits, where $b$
is the base, longer than the theoretical optimum, but to my knowledge there
is no published justification for this claim.
This only seems true when using near-infinite precision arithmetic so that
the process is carried out with no rounding errors.
An excellent description of implementation details is available at
http://www.arturocampos.com/ac_range.html
A recent work \cite{MNW98} which proposes several changes to arithmetic
encoding for efficiency actually re-discovers many of the principles
behind range encoding, and presents a good theoretical analysis of them.
End of stream is handled by writing out the smallest number of bits that
ensures that the stream will be correctly decoded regardless of the value of
any subsequent bits.
ec_tell() can be used to determine how many bits were needed to decode
all the symbols thus far; other data can be packed in the remaining bits of
the input buffer.

If there is a potential to propagate a carry over several symbols, they are

This gives a theoretical limit of a few billion symbols in a single packet on
