MediaStreamTrackAudioSourceNode
The MediaStreamTrackAudioSourceNode interface is a type of AudioNode which represents a source of audio data taken from a specific MediaStreamTrack obtained through the WebRTC or Media Capture and Streams APIs.
The audio itself might be input from a microphone or other audio sampling device, or might be received through a RTCPeerConnection, among other possible options.
A MediaStreamTrackAudioSourceNode has no inputs and exactly one output, and is created using the AudioContext.createMediaStreamTrackSource() method. This interface is similar to MediaStreamAudioSourceNode, except it lets you specifically state the track to use, rather than assuming the first audio track on a stream.
