An audio signal processing apparatus includes a high-frequency components extraction means for extracting high-frequency components higher than a predetermined cutoff frequency from the input audio signal and supplying them to satellite speakers by way of a predetermined high frequency range amplifier, a low-frequency components extraction means for extracting low-frequency components lower than a predetermined cutoff frequency from the input audio signal, a correlation reducing means for reducing the correlation of the high-frequency components and the low-frequency components of the input audio signal and a delay means for delaying the low-frequency components and supplying them to a subwoofer by way of a predetermined low frequency range amplifier.
