<p>A sound switching device is provided with a sampling frequency converting circuit (1) for converting the sampling frequency of an input signal, a delay adjusting circuit (2) for adjusting and outputting the phases of the signal whose sampling frequency is converted and the other input signal, a switching circuit (3) for selecting a signal from the output signals of the delay adjusting circuit according to a control signal. This makes it possible to reduce noise in switching the reproduction of one of different sound signals to that of another signal.</p> |
