AudioTrack: sourceBuffer property

Limited availability

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

The read-only AudioTrack property sourceBuffer returns the SourceBuffer that created the track, or null if the track was not created by a SourceBuffer or the SourceBuffer has been removed from the MediaSource.sourceBuffers attribute of its parent media source.

Value

A SourceBuffer or null.
