Beschreibung
Zusammenfassung:	In an audio processing apparatus of the present invention, one or two audio signals selected from a surround rear left audio signal, a left outer audio signal and a left upper audio signal is (are) amplified to be outputted from a speaker terminal(s) corresponding to this (these) channel(s) without necessity to provide amplifiers of all channels. When the surround rear left audio signal is included, a switch S 13 a is turned ON to supply the surround rear left audio signal amplified by an amplifier 12a to a SP terminal 14a. When the left outer audio signal is included, a switch 13b is turned ON to supply the left outer audio signal amplified by the amplifier 12a to a SP terminal 14b, or a switch 13c is turned ON to supply the left outer audio signal amplified by an amplifier 12b to the SP terminal 14b. When the left upper audio signal is included, a switch 13d is turned ON to supply the left upper audio signal amplified by the amplifier 12b to a SP terminal 14c.
