| description | PROBLEM TO BE SOLVED: To provide an "audio system" capable of expressing a feeling of spread in an audio sound and preventing the audio sound from becoming unnatural. SOLUTION: The audio system is provided with a decode processing unit 100 for decoding audio data of a discrete format; an SL signal generating unit 20 and a BL signal generating unit 40 for receiving an LS signal and an RS signal output from the decode processing unit 100, and generating an SL signal or a BL signal by extracting a component having high correspondence with the LS signal in the RS signal and subtracting the component from the LS signal; and an SR signal generating unit 30 and a BR signal generating section 50 for generating an SR signal or a BR signal by extracting a component having high correspondence with the RS signal in the LS signal and subtracting the extracted signal from the RS signal. The SL signal generating section 20 etc. generates an SL signal etc. by updating a filter coefficient of an adaptive filter using an adaptive algorithm. COPYRIGHT: (C)2007,JPO&INPIT |
