feat: add AudioSource/AudioSink traits + G.711 codec#21
Merged
Conversation
Two upstream-shaped additions for the WaveKat audio ecosystem:
- `audio_io::{AudioSource, AudioSink}` — the producer/consumer seam the
whole audio pipeline is drawn against. Frames keyed on `AudioFrame`
so the trait doesn't have to know about the codec.
- `codec::g711` — PCMU / PCMA encode/decode + `G711Codec` enum.
Codecs are consumer-layer (`wavekat-sip` stays codec-agnostic) but
benefit from a shared home so future consumers (wavekat-asr,
wavekat-voice, an eventual `wavekat-agent`) don't each reimplement.

- audio_io: source-drain ordering, sink backpressure pattern, per-frame sample-rate preservation, compile-time Send check. - g711: per-codeword decode fixed-point sweep, full-codeword-space no-panic, distinctness sanity, PCMU vs PCMA cross-check, slice encode/decode buffer-append behavior, sine-wave round-trip with a mean-error bound, RFC 3551 payload-type pinning. Also document the new modules under "What Belongs Here" and the repo-structure tree in CLAUDE.md. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Codecov Report✅ All modified and coverable lines are covered by tests. 📢 Thoughts on this report? Let us know! |
Replace seg_for's loop with leading_zeros bit-math so it can't fall through, and remove the unreachable seg >= 8 arms in linear_to_ulaw and linear_to_alaw. Inputs are already bounded to [0, 0x7FFF], so the guards never fired and showed up as missing patch coverage. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Summary
Two upstream-shaped additions for the WaveKat audio ecosystem:
audio_io::{AudioSource, AudioSink}— the producer/consumer seam any audio pipeline composes against.Send-bounded traits withSend-bounded future returns, keyed on `AudioFrame`. Concrete impls live in their consuming crates (cpal mic in `wavekat-voice`, a future agent-backed impl in `wavekat-agent`) so the trait stays neutral.CLAUDE.md updated to document the new modules under "What Belongs Here" and the repo-structure tree.
Why this lives here
Originally drafted inside `wavekat-voice` as part of the M1 audio scaffolding (doc 12's "one architectural seam worth drawing now"). Moved upstream so that:
The `wavekat-sip` port-plan explicitly excludes codecs from that crate, so they don't go there.
Test plan
39 unit tests in the lib + 3 doctests. Coverage:
