The MediaStreamAudioDestinationNode interface represents an audio destination consisting of a WebRTC MediaStream with a single AudioMediaStreamTrack, which can be used in a similar way to a MediaStream obtained from navigator.mediaDevices.getUserMedia().

It is an AudioNode that acts as an audio destination, created using the AudioContext.createMediaStreamDestination() method.

MediaStreamAudioDestinationNode()

Creates a new MediaStreamAudioDestinationNode object instance.

Inherits properties from its parent, AudioNode.

MediaStreamAudioDestinationNode.stream

A MediaStream containing a single MediaStreamTrack whose kind is audio and with the same number of channels as the node. You can use this property to get a stream out of the audio graph and feed it into another construct, such as a Media Recorder.

Inherits methods from its parent, AudioNode.

See AudioContext.createMediaStreamDestination() for example code that creates a MediaStreamAudioDestinationNode and uses it as a source for audio to be recorded.
