The EventTarget.
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).
This implementation accepts a settings object of type EventListenerOptions.

Represents an integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node.
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 way channels must be matched between the node's inputs and outputs.
Represents an enumerated value describing the way channels must be matched between the node's inputs and outputs.
Represents an enumerated value describing the meaning of the channels.
Represents an enumerated value describing the meaning of the channels. This interpretation will define how audio up-mixing and down-mixing will happen.
The possible values are "speakers" or "discrete".
Allows us to connect one output of this node to one input of an audio parameter.
Allows us to connect one output of this node to one input of an audio parameter.
Allows us to connect one output of this node to one input of another node.
Allows us to connect one output of this node to one input of another node.
Returns the associated AudioContext, that is the object representing the processing graph the node is participating in.
Returns the associated AudioContext, that is the object representing the processing graph the node is participating in.
Allows us to disconnect the current node from another one it is already connected to.
Allows us to disconnect the current node from another one it is already connected to.
The index describing which output of the AudioNode is going to be disconnected.
Dispatches an Event at the specified EventTarget, invoking the affected EventListeners in the appropriate order.
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().

Is an a-rate AudioParam representing the amount of gain to apply.
Returns the number of inputs feeding the node.
Returns the number of inputs feeding the node. Source nodes are defined as nodes having a numberOfInputs property with a value of 0.
Returns the number of outputs coming out of the node.
Returns the number of outputs coming out of the node. Destination nodes — like AudioDestinationNode — have a value of 0 for this attribute.

The GainNode interface represents a change in volume. It is an AudioNode audio-processing module that causes a given gain to be applied to the input data before its propagation to the output. A GainNode always has exactly one input and one output, both with the same number of channels.
The gain is a unitless value, changing with time, that is multiplied to each corresponding sample of all input channels. If modified, the new gain is applied using a de-zippering algorithm in order to prevent unaesthetic 'clicks' from appearing in the resulting audio.
The GainNode is increasing the gain of the output.
