ABSTRACT:
An echo generating apparatus includes an echo effect generator for producing reverberative echo effect by delaying an input audio signal; a band limit filter for limiting the frequency band of the output signal of the echo effect generator; a first calculator for delivering an output signal by calculating the input audio signal and the output signal of the band limit filter; and a frequency characteristic compensator for emphasizing the signal of the frequency band attenuated by the band limit filters. The echo effect generator consists of a second calculator for calculating the input audio signal and the output signal of the band limit filter, an analog delay means for delaying the output signal of the second calculator, and a clock generator for generating an operation clock signal for the analog delay means. A long reverberative echo time is maintained without the necessity of increasing the number of signal delay stages or enlarging the scale thereof. The apparatus is free from spurious radiation or deterioration of the S/N in the data signal. And the number of required component elements is minimized to curtail the production cost.
