Create a reverberation effect:

Simulate reverberation of a small hall:

Simulate the reverberation of real space using an impulse response recording:

Control the size of the reverberating environment:

Use a value of 1 to create reverberation that decays very slowly:

Control the attenuation of high frequencies in the reverberated signal:

Use a value of 1 to get a maximal amount of high-frequency filtering:

The mix parameter controls the ratio between the original signal and the reverberated signal:

Use a mix value of 0 to return the original signal ("dry"):

Use a value of 1 to return the reverberated signal ("wet") only:

Use a value between 0 and 1 to control the ratio between the "dry" and "wet" signals:

AudioReverb can be used to insert a sound in a space different from the one it was recorded in:

Create sound effects by using the convolution reverb with audio objects that are not impulse responses:

If the input is a mono audio object, the impulse response can have an arbitrary number of channels:

The output will have the same number of channels as the impulse response:

If the input is an audio object with n channels, the impulse response can have either 1 or n channels:

The output will have the same number of channels as the input:

The ExampleData["Audio"] collection holds several recordings of impulse responses:
