ABSTRACT:
A time-modulated delay system having an input and a plurality of time-modulated output taps including storage means having a multiplicity of storage locations for storing successive portions of an interval of the input signal; a write address generator circuit for designating the address of locations in the storage means in which the successive portions of the input signal are stored; an output tap identifier circuit for sequentially identifying each output tap; a read address generator circuit responsive to the tap identifier circuit for designating a random address in the storage means from which a portion of the input signal is to be read for each time-modulated tap identified to produce a random modulation of the temporal pattern of the output taps; and a distribution circuit, responsive to the output tap identifier circuit, for delivering each portion of the input signal read out of the storage means to the corresponding identified tap. The delay system may be used in an audio reverberation simulator to provide both time-modulated output taps and temporally fixed output taps.
