Claude	e7b1c3372a	feat: Android VoIP client — Phase 2 (JNI bridge, Compose UI, AEC pipeline wiring) ... - JNI bridge with 8 extern functions (init, startCall, stopCall, setMute, setSpeaker, getStats, forceProfile, destroy) with panic catching - Kotlin engine layer: WzpEngine JNI wrapper, WzpCallback interface, CallStats data class with JSON deserialization - Jetpack Compose UI: InCallScreen with quality indicator (green/yellow/red), mute/speaker/hangup buttons, stats overlay, duration timer - CallActivity with RECORD_AUDIO permission handling, Material3 theme - CallService foreground service with WakeLock, WiFi lock, notification - AudioRouteManager for speaker/earpiece/Bluetooth SCO switching - AEC wired into CallEncoder pipeline: AEC → AGC → denoise → silence → encode - AEC farend reference fed from decode path to encode path in pipeline - Engine exposes set_aec_enabled/set_agc_enabled via AtomicBool flags Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-04 18:16:38 +00:00
Claude	26e9c55f1f	feat: Android VoIP client — Phase 1 (audio quality, network adaptation, crate skeleton) ... - New wzp-android crate with Oboe C++ backend, lock-free SPSC ring buffers, engine orchestrator, codec pipeline, and Android Gradle project structure - AEC (NLMS adaptive filter), AGC (two-stage with fast attack/slow release), windowed-sinc FIR resampler replacing linear interpolation (wzp-codec) - Opus encoder tuning: complexity 7 default, set_expected_loss support - Mobile jitter buffer: asymmetric EMA (fast up/slow down), handoff spike detection with 2s cooldown, configurable safety margin - Network-aware quality control: cellular-specific thresholds, faster downgrade on cellular, proactive tier drop on WiFi→cellular handoff, FEC ratio boost during network transitions - Handoff detection in PathMonitor via RTT jitter spike analysis Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-04 18:07:55 +00:00
