The RTCAudioSourceStats dictionary's audioLevel property represents the audio level of the media source.
The level is averaged over some small implementation-dependent interval. Users can alternatively calculate the average audio level over some arbitrary duration using the algorithm described in the RTCAudioSourceStats description.
Note: For audio levels of remotely sourced tracks, see RTCInboundRtpStreamStats.audioLevel.
