Appearance

Interface: AudioSource ​

Defined in: types.ts:133

An injected audio producer — the microphone, a file player, a test script. The engine consumes frames the way SpeechPlayer consumes an injected sink: same inversion, source instead of sink. Both engines take 24 kHz PCM16 mono, so one capture path serves either.

Properties ​

sampleRate ​

readonly sampleRate: number

Defined in: types.ts:135

Samples per second of the produced PCM16. Both engines want 24000.

Methods ​

flush()? ​

optional flush(): void

Defined in: types.ts:145

Emit the buffered partial frame NOW. The handle calls this at segment end, before the commit — a warm mic buffering ~100 ms frames would otherwise clip the segment's tail off every utterance.

Returns ​

void

level()? ​

optional level(): number

Defined in: types.ts:147

Latest frame's level, 0–1 (for meters). Optional.

Returns ​

number

start() ​

start(onFrame): Promise<void>

Defined in: types.ts:137

Begin producing; each frame is little-endian PCM16 mono bytes.

Parameters ​

onFrame ​

(pcm16) => void

Returns ​

Promise<void>

stop() ​

stop(): void

Defined in: types.ts:139

Stop producing (idempotent). Releases the device for a real mic.

Returns ​

void
