Abstract
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.
