ABSTRACT:
A stereo or two channel electronic reverberation device is disclosed comprising an analog delay device which receives audio signals and provides delayed output signals at a plurality of outputs, with the time delay period of each output being different from the delay period of other outputs. Two summing devices each receive inputs from different combinations of the analog delay device outputs to provide two different signals having different reverb components. An additional output delay device is also provided which receives the last output from the analog delay device, delays this signal a time period substantially greater than the time period between any two adjacent analog delay device outputs, and provides this substantially greater delayed signal to only one of said summing devices.
