MediaElementAudioSourceNode class

The interface represents an audio source consisting of an HTML5 <audio> or <video> element. It is an AudioNode that acts as an audio source. A MediaElementSourceNode has no inputs and exactly one output, and is created using the AudioContext.createMediaElementSource() method. The amount of channels in the output equals the number of channels of the audio referenced by the HTMLMediaElement used in the creation of the node, or is 1 if the HTMLMediaElement has no audio.
