ABSTRACT:
A reverberation sound producing apparatus includes a nonuniformly tapped delay line, a summing circuit applying an audio signal to the input of the tapped delay line and a feedback path coupling the output taps of the delay line back to its input through the summing circuit. A separate output path couples the reverberation signal from the feedback path to an output amplifier and speaker system. The feedback path is adjusted for minimizing loop gain and the effect of ripple in the frequency response of the delay line while the output path is adjusted for providing a smoothly decaying reverberation signal.
