Abstract
An electronic sound processor creates reverberation effects using a simulated impulse function. The simulated impulse response is generated by combining frequency bands of white noise. The power of each band decays exponentially in time. The time constants are generated from the characteristics of a real or imaginary listening space. A reverberated sound signal is generated from an original sound signal by convolution of the original signal and the simulated impulse response. The method can adapted to generated stereophonic signals and to generate a forward and inverse reverb effect using only one set of multiplications.
