<P>PROBLEM TO BE SOLVED: To provide an audio device capable of implementing good-quality crosstalk cancellation processing that does not cause sound quality deterioration. <P>SOLUTION: The audio device comprises: first signal output means for outputting a right signal as the driving signal of a right main speaker; second signal output means for outputting a left signal as the driving signal of a left main speaker; reversed-phase component extraction means for extracting the reversed-phase component signal of the right and left signals; signal processing means for assigning a transfer characteristic for crosstalk component cancellation to the reversed-phase component signal; third signal output means for outputting the reversed-phase component signal after phase reversion as the driving signal of one speaker for cancellation; and fourth signal output means for outputting the reversed-phase component signal to which the transfer characteristic is assigned as the driving signal of the other speaker for cancellation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
