There are three audio clips in this Demonstration: the original sound file, a speaker cabinet impulse response, and the impulse response in a small concert hall. (The initial audio clip is a distorted guitar recorded directly into a computer.) Any one of the three source files can be played or analyzed using the first control "analyze". The checkboxes represent the two available convolutions.


The speaker cabinet impulse lets us simulate the dynamics of a real speaker cabinet. Finally, we can use that convolution principle to simulate the sound being played in a concert hall.
