WaveShaperNode

{{ APIRef("Web Audio API") }}

The WaveShaperNode interface represents a non-linear distorter.

It is an {{domxref("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

• {{domxref("WaveShaperNode.WaveShaperNode", "WaveShaperNode()")}}
  • : Creates a new instance of a WaveShaperNode object.

Instance properties

Inherits properties from its parent, {{domxref("AudioNode")}}.

• {{domxref("WaveShaperNode.curve")}}
  • : A {{jsxref("Float32Array")}} of numbers describing the distortion to apply.
• {{domxref("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, {{domxref("AudioNode")}}.

Example

See BaseAudioContext.createWaveShaper() for example code.
