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.
| Number of inputs | 1 |

| Number of outputs | 1 |
| Channel count mode | "max" |
| Channel count | 2 (not used in the default count mode) |
| Channel interpretation | "speakers" |
WaveShaperNode()
Creates a new instance of an WaveShaperNode object.
Inherits properties from its parent, AudioNode.
WaveShaperNode.curve
A Float32Array of numbers describing the distortion to apply.
WaveShaperNode.oversample
An 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.
