web.GainNode
The GainNode interface represents a change in volume. It is an audio-processing module that causes a given gain to be applied the input data before its propagation to the output. A GainNode has exactly one input and one output, both with the same number channels.

constructorcljs
Constructor.
The GainNode() constructor of the Web Audio API creates a new web.GainNode object which an audio.AudioNode that represents a change in volume.
Inherits parameters from the audio.AudioNodeOptions dictionary.
\tcontext
\tA reference to an audio.AudioContext.
\toptions Optional
\tOptions are as follows:
\t\tgain: The amount of gain to apply. This parameter is a-rate and it's nominal range is (-∞,+∞). The default is 1.
