PROBLEM TO BE SOLVED: To provide a reproducing device which can superpose sounds corresponding to music. SOLUTION: This reproducing device is provided with a BPF 2 which divides an inputted audio signal to plural bands, an envelope detection circuit 3 which detects an envelope value in each band, a register 5-1-2 which holds the envelope value for each band, a register 5-1-3 which shifts envelope values in time series to hold them, a difference circuit 5-1-1 which operates different values between preceding envelope values and current envelope values, a sound source generator 16 which generates plural effect sounds, a sound synthesizer 20 which superposes the inputted audio signal and effect sounds generated from the sound source generator 16, and a sound source selector 15 which switches a sound source generated from the sound source generator 16 based on operated difference values, and features of music are recognized by difference values to superpose sounds. |
