The WaveShaperNode interface represents a non-linear distorter.
It is an AudioNode that uses a curve to apply a wave shaping distortion to the signal. Beside obvious distortion effects, it is often used to add a warm feeling to the signal.
A WaveShaperNode always has exactly one input and one output.

WaveShaperNode()Creates a new instance of an WaveShaperNode object.
Inherits properties from its parent, AudioNode.
WaveShaperNode.curveA Float32Array of numbers describing the distortion to apply.
WaveShaperNode.oversampleAn enumerated value indicating if oversampling must be used. Oversampling is a technique for creating more samples (up-sampling) before applying the distortion effect to the audio signal.
No specific method; inherits methods from its parent, AudioNode.
See BaseAudioContext.createWaveShaper() for example code.
