WaveShaperNode

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.

Constructor

WaveShaperNode()

Creates a new instance of an WaveShaperNode object.

Instance properties

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.

Instance methods

No specific method; inherits methods from its parent, AudioNode.
