MediaStreamAudioSourceNode
The MediaStreamAudioSourceNode interface represents an audio source consisting of a WebRTC MediaStream (such as a webcam or microphone). 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.createMediaStreamSource method. The amount of channels in the output equals the number of channels in AudioMediaStreamTrack. If there is no valid media stream, then the number of output channels will be one silent channel.
- Number of inputs: 0
- Number of outputs: 1
- Channel count: defined by the AudioMediaStreamTrack passed to the AudioContext.createMediaStreamSource method that created it.

The EventTarget.addEventListener() method registers the specified listener on the EventTarget it's called on. The event target may be an Element in a document, the Document itself, a Window, or any other object that supports events (such as XMLHttpRequest).

Dispatches an Event at the specified EventTarget, invoking the affected EventListeners in the appropriate order. The normal event processing rules (including the capturing and optional bubbling phase) apply to events dispatched manually with dispatchEvent().

Inherited fields
Represents an integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node. Its usage and precise definition depend on the value of AudioNode.channelCountMode.

Represents an enumerated value describing the meaning of the channels. This interpretation will define how audio up-mixing and down-mixing will happen.
