The number of digital-analog converters is decreased in an audio processing apparatus that outputs an audio signal to not only a device disposed in a main room but also a device disposed in a sub-room. The audio processing apparatus includes a digital-analog conversion unit for outputting an extended left audio signal and an extended right audio signal in an analog format, or for outputting a sub-room left audio signal and a sub-room right audio signal in the analog format; and an input switch unit that switches between a supply of a combination of the extended left audio signal and the extended right audio signal to the digital-analog conversion unit and a supply of a combination of the sub-room left audio signal and the sub-room right audio signal to the digital-analog conversion unit.
