Enum AudioSink 

pub enum AudioSink {
    Wav(Box<WavWriter<File>>),
    RawPcm,
    None,
}

Where synthesised PCM goes, and the audio_chunk events that describe it.

The two destinations are mutually exclusive by contract (AGENTS.md agent ergonomics): either events own stdout and audio goes to -o PATH, or --stream raw gives stdout to PCM and every event goes to stderr. Raw bytes and NDJSON are never interleaved on one stream, so this type owns the decision once instead of leaving it to each call site.

audio_chunk reports the bytes written, never the bytes themselves.

Variants

Wav(Box<WavWriter<File>>)

A WAV file. The header is finalised on [AudioSink::finish], so a run cut short still leaves a playable file describing the samples that landed.

RawPcm

Raw little-endian 16-bit PCM on a caller-supplied stream (--stream raw).

None

--check and other non-synthesising paths.
