An artificial stereophonic circuit which includes a monophonic signal input terminal, a signal output terminal of one of an L channel and an R channel which are connected to the signal input terminal, a phase-shifting circuit having an input side connected to the signal input terminal, and a signal output terminal of the other channel of the L channel and the R channel having an output side connected to the phase-shifting circuit. The phase-shifting circuit has an almost equal gain in a full frequency band of an input signal, and a phase shift for a change from 0 to 180 degrees according to an increase in a frequency of the input signal is carried out. The change of the phase can be minimized and a natural stereophonic effect can be realized. Moreover, only one capacitor is enough and only one pin for external attachment is enough for wholly forming an IC.
