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

The WaveShaperNode() constructor of the Web Audio API creates a new {{domxref("WaveShaperNode")}} object which is an {{domxref("AudioNode")}} that represents a non-linear distorter.

Syntax

new WaveShaperNode(context, options)

Parameters

• context

  • : A reference to an {{domxref("AudioContext")}}.

• options {{optional_inline}}

  • : Options are as follows:

    • curve
      • : The shaping curve used for the waveshaping effect. The input signal is nominally within the range [-1;1].
    • oversample
      • : Specifies what type of oversampling (if any) should be used when applying the shaping curve. Valid values are 'none', '2x', or '4x'. The default is 'none'.
    • channelCount
      • : Represents an integer used to determine how many channels are used when up-mixing and down-mixing connections to any inputs to the node. (See {{domxref("AudioNode.channelCount")}} for more information.) Its usage and precise definition depend on the value of channelCountMode.
    • channelCountMode
      • : Represents an enumerated value describing the way channels must be matched between the node's inputs and outputs. (See {{domxref("AudioNode.channelCountMode")}} for more information including default values.)
    • channelInterpretation
      • : Represents an enumerated value describing the meaning of the channels. This interpretation will define how audio up-mixing and down-mixing will happen. The possible values are "speakers" or "discrete". (See {{domxref("AudioNode.channelCountMode")}} for more information including default values.)

Return value

A new {{domxref("WaveShaperNode")}} object instance.
