ConvolverNode()

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:

• audioBuffer: 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.
