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
.
Example
See BaseAudioContext.createWaveShaper()
for example code.
