|
||||||
//! [`AudioBackend`] contract as a no-op: no microphone is captured and nothing is
|
//! is unchanged:
|
||||||
//! played. It deliberately pulls in no extra dependency — `cpal` is added only
|
|
||||||
//! when the real implementation arrives.
|
|
||||||
//!
|
//!
|
||||||
//! Phase 1 will replace this with cpal streams on the WASAPI host, mapping:
|
//! - **Capture**: mono, 48 kHz, S16 PCM, emitted as `Vec<i16>` frames of
|
||||||
//! - `start_capture` → input stream, f32→i16, mono 48 kHz, into `tx`;
|
//! [`CAPTURE_FRAME`] (960 = 20 ms) samples — matching the encoder/jitter frame.
|
||||||
//! - `start_playback` → output stream draining a `ringbuf`, keeping `ring_fill`
|
//! - **Playback**: stereo interleaved ([`PLAYBACK_CHANNELS`]) S16 PCM at 48 kHz,
|
||||||
//! updated so the existing hardware-clock pacing in the mixer keeps working;
|
//! drained from a ring buffer that is paced to the device's hardware clock via
|
||||||
//! - `stop` → drop the streams.
|
//! `ring_fill` exactly as the PipeWire backend does.
|
||||||
|
//!
|
||||||
|
//! ## Threading and the `!Send` stream
|
||||||
|
//!
|
||||||
|
//! `cpal::Stream` is `!Send` (some backends require it to be created and dropped
|
||||||
|
//! on the same thread), but [`AudioBackend`] is `Send + Sync` and the backend is
|
||||||
|
//! shared through an `Arc`. So the stream never lives in the struct: each of
|
||||||
|
//! `start_capture`/`start_playback` spawns one owning thread that builds the
|
||||||
|
//! stream, plays it, and keeps it alive until the per-worker `running` flag flips
|
||||||
|
//! (set by `stop`). The struct holds only `Send` handles (the flag + the join
|
||||||
|
//! handle). The stream's RT callback does the actual audio work; the owning
|
||||||
|
//! thread additionally feeds the playback ring from the network mixer.
|
||||||
|
//!
|
||||||
|
//! ## Sample rate
|
||||||
|
//!
|
||||||
|
//! The whole pipeline assumes 48 kHz (Opus + the 960-sample frame). Phase 1 only
|
||||||
|
//! selects a native-48 kHz device config; if the device can't do 48 kHz we return
|
||||||
|
//! a clear error rather than silently producing pitch-shifted audio. Arbitrary
|
||||||
|
//! sample-rate support (resampling) is a Phase 1.1 follow-up.
