ConvolverNode

The ConvolverNode interface represents a linear convolution effect, that can be applied to a signal given an impulse response. This is the easiest way to achieve echo or reverb effects.

AudioNode properties

Number of inputs	1
Number of outputs	1
Channel count	2
Channel count mode	clamped-max
Channel interpretation	speakers

info

Convolver is a node with tail-time, which means, that it continues to output non-silent audio with zero input for the length of the buffer.

Constructor

BaseAudioContext.createConvolver(options: ConvolverNodeOptions)

interface ConvolverNodeOptions {
  buffer?: AudioBuffer | null; // impulse response
  disableNormalization?: boolean; // if normalization of output should be applied, true by default
}

Properties

It inherits all properties from AudioNode and has no individual ones.

caution

Linear convolution is a heavy computational process, so if your audio has some weird artefacts that should not be there, try to decrease the duration of impulse response buffer.
