Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
TheMediaStreamTrackAudioSourceNode interface is a type ofAudioNode which represents a source of audio data taken from a specificMediaStreamTrack obtained through theWebRTC orMedia Capture and Streams APIs.
The audio itself might be input from a microphone or other audio sampling device, or might be received through aRTCPeerConnection, among other possible options.
AMediaStreamTrackAudioSourceNode has no inputs and exactly one output, and is created using theAudioContext.createMediaStreamTrackSource() method. This interface is similar toMediaStreamAudioSourceNode, except it lets you specifically state the track to use, rather than assuming the first audio track on a stream.
