Claim:
1. An audio signal processing apparatus configured to process a plurality of audio signals of a shared-volume stereo system, the audio signal processing apparatus comprising: a plurality of signal processing channels, filtering out high-frequency components and low-frequency components of the audio signals and performing a signal processing operation on the low-frequency components of the audio signals to generate a low-frequency modulation signal, wherein the signal processing channels sum up the high-frequency components of the audio signals and the low-frequency modulation signal to generate a plurality of audio reproduction signals, so as to drive corresponding loudspeakers in the shared-volume stereo system according to the audio reproduction signals, and a shared part of the signal processing channels sums up the low-frequency components of the audio signals, and the shared part of the signal processing channels comprises a divider configured to perform a division operation on the summed low-frequency components of the audio signals, so as to generate the low-frequency modulation signal.
