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.

Value

Examples

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