Details

• Capture constraint: requests getUserMedia({ audio: { sampleRate } }) for the microphone.

• Typical values: 48000 (default), 44100, 32000, 16000. Browsers may clamp or ignore unsupported values.

• Encoding: Opus encodes at 48kHz internally; this setting mainly affects capture and any pre-encode processing.

• Do not confuse with:

  • &outboundsamplerate: WebAudio processing context sample rate (publisher-side).

  • &samplerate: Playback sample rate (viewer-side PCM).
