The ConvolverNode
interface is an AudioNode
that performs a Linear Convolution on a given AudioBuffer
, often used to achieve a reverb effect. A ConvolverNode
always has exactly one input and one output.
Note: For more information on the theory behind Linear Convolution, see the W3C Web Audio API spec section, Linear Effects Using Convolution, or read the The Wikipedia Linear Convolution Article.

Properties
Inherits properties from its parent, AudioNode
.
ConvolverNode.buffer
- A mono, stereo, or 4-channel
AudioBuffer
containing the (possibly multichannel) impulse response used by theConvolverNode
to create the reverb effect. ConvolverNode.normalize
- A boolean that controls whether the impulse response from the buffer will be scaled by an equal-power normalization when the
buffer
attribute is set, or not.
Methods
No specific method; inherits methods from its parent, AudioNode
.
