High and low frequency components C, Care generated by causing a center channel audio signal Cn to pass through a high-pass filter HPF and a low-pass filter LPF, and the high frequency component Cis supplied to the center channel loudspeaker SP. Also, two low frequency components C, C, which have a different phase mutually, are generated by causing the low frequency component Cto pass through phase shifters. An synthesized audio signal SL is generated by synthesizing the low frequency component Cand the front-left channel audio signal FL, and then supplied to the front-left channel loudspeaker SP. An synthesized audio signal SR is generated by synthesizing the low frequency component Cand the front-right channel audio signal FR, and is supplied to the front-right channel loudspeaker SP.

Audio reproducing system

In an audio apparatusto which plural kinds of audio signals of different numbers of channels are input, a sound field control sectionwhich performs a sound field control on the audio signals on the basis of a sound field control data is provided, and the sound field control data is stored in a memoryfor each of the kinds of audio signals.
