MediaElementAudioSourceNode
The MediaElementAudioSourceNode interface represents an audio source consisting of an HTML <audio> or <video> element. It is an AudioNode that acts as an audio source.
A MediaElementAudioSourceNode has no inputs and exactly one output, and is created using the createMediaElementSource() method. The number 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.
