    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.

    Inherits properties from its parent, AudioNode.

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


    No specific method; inherits methods from its parent, AudioNode.
