Field	Default	Description

bitrateBps	auto	Target bitrate, capped at 512 kbps.
sampleRate	48000	Output rate snapped to a supported encode rate.

Equivalent nodes with the same input, filters, and config are shared across sinks. RTC sinks publish raw audio through their SDK and reject encoded input.
