WaveShaperNode

The WaveShaperNode interface represents non-linear signal distortion effects. Non-linear distortion is commonly used for both subtle non-linear warming, or more obvious distortion effects.

Constructor

constructor(context: BaseAudioContext, waveShaperOptions?: WaveShaperOptions)

WaveShaperOptions

Inherits all properties from AudioNodeOptions

Parameter	Type	Default	Description
curve Optional	Float32Array	-	Array representing curve values
oversample Optional	OverSampleType	-	Value representing oversample property

Or by using BaseAudioContext factory method: BaseAudioContext.createStereoPanner()

Properties

It inherits all properties from AudioNode.

AudioNodeproperties

Name	Type	Description
curve	Float32Array | null	The shaping curve used for waveshaping effect.
oversample	OverSampleType	Specifies what type of oversampling should be used when applying shaping curve.

Methods

WaveShaperNode does not define any additional methods. It inherits all methods from AudioNode.

Remarks

curve

• Default value is null
• Contains at least two values.
• Subsequent modifications of curve have no effects. To change the curve, assign a new Float32Array object to this property.

oversample

• Default value none
• Value of 2x or 4x can increases quality of the effect, but in some cases it is better not to use oversampling for very accurate shaping curve.

OverSampleType

Type definitions

// Do not oversample | Oversample two times | Oversample four times
type OverSampleType = 'none' | '2x' | '4x';
