RTCInboundRtpStreamStats: audioLevel property

Limited availability

This feature is not Baseline because it does not work in some of the most widely-used browsers.

The audioLevel property of the RTCInboundRtpStreamStats dictionary indicates the audio level of the received (remote) track.

The audioLevel is averaged over some small interval, using the algorithm described under totalAudioEnergy. The interval used is implementation dependent.

Note: The value is undefined for video streams.

Value

A real number.

The value is between 0..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.
