ABSTRACT:
A sound effect-creating device adds a reverberation tone signal to a monaural original tone signal by the use of a reverberation circuit, and delays a monaural reverberation tone signal output from the reverberation circuit by different delay amounts by the use of a plurality of delay circuits. At least one of delayed monaural reverberation tone signals from the delay circuits and the monaural reverberation tone signal are added up by a plurality of mixing circuits, and the resulting signals are delivered therefrom. The plurality of delay circuits are each constructed such that a delayed monaural reverberation tone signal output from one of the delay circuits and/or one from another of the delay circuits is/are input to the one of the delay circuits.
