feat: file-based audio testing + Hetzner build scripts
CLI modes: - --send-tone <secs>: send 440Hz test tone (no mic needed) - --record <file.raw>: save received audio to raw PCM file - --help: usage info - Combine: --send-tone 10 --record out.raw Raw PCM format: 48kHz mono s16le Play with: ffplay -f s16le -ar 48000 -ac 1 out.raw Build scripts: - scripts/build-linux.sh: Hetzner VPS build with auto-cleanup - scripts/cleanup-builder.sh: kill stale builders Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

//! WarzonePhone CLI test client.

//! Usage: wzp-client [--live] [relay-addr]
|
||||
//! Usage:
|
||||
//! wzp-client [relay-addr] Send silence frames (connectivity test)
|
||||
//! wzp-client --live [relay-addr] Live mic/speaker mode
|
||||
//! wzp-client --send-tone 10 [relay-addr] Send 10s of 440Hz test tone
|
||||
//! wzp-client --record out.raw [relay-addr] Record received audio to raw PCM file
|
||||
//! wzp-client --send-tone 10 --record out.raw [relay-addr] Both at once
|
||||
//!
|
||||
//! Without `--live`: sends silence frames for testing.
|
||||
//! With `--live`: captures microphone audio and plays received audio through speakers.
|
||||
//! Raw PCM files are 48kHz mono 16-bit signed little-endian.
|
||||
//! Play with: ffplay -f s16le -ar 48000 -ac 1 out.raw
|

//! Or convert: ffmpeg -f s16le -ar 48000 -ac 1 -i out.raw out.wav
