Abstract (en)
[origin: EP0480561A2] A reverberation sound generating apparatus, comprising a plurality of comb filters (11-1n) each having a delay element and a coefficient multiplier, and an adder (2) for adding output signals of the comb filters, wherein the numbers of the samples corresponding to each delay time of the comb filters are mutually prime. With such arrangement, it is possible that the impulse responses of each of the comb filters do not coincide with each other almost at all within the reverberation time. Thus, reverberation sound is not deviated over time and is dispersed uniformly, providing satisfactory reverberation tone quality. <IMAGE>
