The audio signal processing apparatus includes a plurality of signal processing channels. The signal processing channels are configured to filter the audio signals to obtain high-frequency components and low-frequency components. The signal processing channels perform a signal processing operation on the low-frequency components to generate a low-frequency modulation signal. The signal processing channels sum up the high-frequency components and the low-frequency modulation signal to reproduce a plurality of audio reproduction signals. The signal processing channels drive loudspeakers of the shared-volume stereo system according to the audio reproduction signals. Furthermore, an audio signal processing method is also provided."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Audio signal processing method for out-of-phase attenuation of shared enclosure volume loudspeaker systems and apparatus using the same","description":"An audio signal processing apparatus configured to process a plurality of audio signals of a shared-volume stereo system is provided.
