ABSTRACT:
A reverb generator comprises a delay circuit for delaying an input audio signal, a feed back path connecting an output port of the delay circuit to its input port, and a phase shifter connected in series to the delay circuit. The phase shifter produces a dispersion in the spectrum of the input audio signal in accordance with frequency dependent delay characteristic in such a manner that the delay time is large in a low frequency range and small in a higher frequency range. By including the phase shifter in the feed back path, one can obtain an output audio signal having a spectrum which is repeatedly subjected to dispersion, thus simulating the effect of dispersion due to the multiple reflections taking place in an actual concert hall.
