Convolution Reverb

Convolution reverb is a software-based process used for digitally simulating the reverberation of a physical or virtual space. It is based on the mathematical convolution operation and uses a pre-recorded audio sample of the impulse response of the space being modeled. The impulse response is typically a recorded pistol shot, balloon popping or the like. Each recording describes the response in that specific position. The impulse response is then convolved with the incoming audio signal to be processed.
