PURPOSE:To automatize an operation to obtain a delayed signal by providing a difference signal generation means to decide whether an input signal is a monaural signal or a stereo signal other than the difference signal generation means to output the difference signal for delay and providing a difference between the input gain of the voice signal of the right and left channel of an original sound at the time of inputting the monaural signal. CONSTITUTION:A difference signal generation circuit 32 to decide whether the input signal is the monaural signal or the stereo signal is provided other than a difference signal generation circuit 17 to output the difference signal for delay. The delay signal is obtained by providing the difference between the input gain of the voice signals L and R against the latter difference signal generation circuit 17 at the time of inputting the monaural signal in accordance with the output of the former difference signal generation circuit 32. Thus, the simplification of operation can be attained, since a switching operation to obtain the delay signal is automatized at the time of inputting the monaural signal. |
