The ConvolverNode() constructor of the Web Audio API creates a new ConvolverNode object instance.

context

A reference to an AudioContext.

options Optional

Options are as follows:

buffer

A mono, stereo, or 4-channel AudioBuffer containing the (possibly multichannel) impulse response used by the ConvolverNode to create the reverb effect.

disableNormalization

A boolean value controlling whether the impulse response from the buffer will be scaled by an equal-power normalization, or not. The default is 'false'.

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 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 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 AudioNode.channelCountMode for more information including default values.)

A new ConvolverNode object instance.

NotSupportedError DOMException

Thrown if the referenced AudioBuffer does not have the correct number of channels, or it has a different sample rate to the associated AudioContext.
