  • Device, method, program, and system for canceling crosstalk when reproducing sound through plurality of speakers arranged around listener
    Patent number: 8320590
    Abstract: In an audio signal processing device, a signal input part receives a plurality of audio signals to be provided to a plurality of speakers, respectively, arranged so as to surround a listener, the speakers including a center speaker, a left speaker and a right speaker. A signal processing part adds a processed audio signal to an audio signal to be provided to the center speaker, the processed signal being obtained by attenuating a summation of audio signals to be provided to the left speaker and the right speaker. The signal processing part attenuates the summation of the audio signals by an attenuation rate which is set between 0 and 1. The signal processing part sets the attenuation rate to an appropriate value effective to suppress crosstalk between sound emitted from the left speaker and sound emitted from the right speaker.
