ConvolverNode: ConvolverNode() constructor
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2021.
The ConvolverNode() constructor of the Web Audio API creates a new
ConvolverNode object instance.
Syntax
new ConvolverNode(context, options)
Parameters
context-
A reference to an
AudioContext. optionsOptional-
Options are as follows:
buffer-
A mono, stereo, or 4-channel
AudioBuffercontaining the (possibly multichannel) impulse response used by theConvolverNodeto 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.channelCountfor more information.) Its usage and precise definition depend on the value ofchannelCountMode. channelCountMode-
Represents an enumerated value describing the way channels must be matched between the node's inputs and outputs. (See
AudioNode.channelCountModefor 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". (SeeAudioNode.channelCountModefor more information including default values.)
Return value
A new ConvolverNode object instance.
Exceptions
NotSupportedErrorDOMException-
Thrown if the referenced
AudioBufferdoes not have the correct number of channels, or it has a different sample rate to the associatedAudioContext.
