Patent ID: 8306243

Claim:
An audio device comprising: in-phase component extracting means for receiving a right signal and left signal of an audio signal, and for extracting an in-phase component signal of the right signal and left signal; anti-phase component extracting means for receiving the right signal and left signal of the audio signal, and for extracting an anti-phase component signal of the right signal and left signal; signal processing means for providing the anti-phase component signal extracted by the anti-phase component extracting means with a transfer characteristic for canceling a crosstalk component; first adding means for adding a phase-inverted signal of the anti-phase component signal provided with the transfer characteristic by the signal processing means and the in-phase component signal extracted by the in-phase component extracting means; and second adding means for adding the anti-phase component signal provided with the transfer characteristic by the signal processing means and the in-phase component signal extracted by the in-phase component extracting means.
