The RTCAudioSourceStats dictionary's totalSamplesDuration property represents the combined duration of all samples produced by the media source over the lifetime of this stats object, in seconds. It does not include samples dropped before reaching this media source.
This can be used with totalAudioEnergy to compute an average audio level over different intervals.
Note: For audio duration of remotely sourced tracks, see RTCInboundRtpStreamStats.totalSamplesDuration.
