RTCAudioSourceStats: audioLevel property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.
The audioLevel property of the RTCAudioSourceStats dictionary 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.
Value
A number between 0 and 1 (linear), where 1.0 represents 0 dBov (decibels relative to full scale (DBFS)), 0 represents silence, and 0.5 represents approximately 6 dB SPL change in the sound pressure level from 0 dBov.
