The MediaStreamAudioSourceNode interface's
read-only mediaStream property indicates the
MediaStream that contains the audio track from which the node is
receiving audio.
This stream was specified when the node was first created, either using the MediaStreamAudioSourceNode.MediaStreamAudioSourceNode constructor or the AudioContext.createMediaStreamSource method.
Implementation
external MediaStream get mediaStream;
