Abstract:
A signal processor that performs crosstalk cancellation on an audio signal that is input, in a distorted acoustic space where two speakers are placed, the two speakers including an X-side speaker and a Y-side speaker, where X denotes one of left and right, and Y denotes the other of left and right. The signal processor causes the Y-side speaker to output a sound of the audio signal and causes the X-side speaker to output a sound of a signal obtained by processing the audio signal using transfer function GCY, where a transfer function between the Y-side speaker and the Y-side ear is defined as GYY, a transfer function between the X-side speaker and the Y-side ear is defined as GXY, and a transfer function obtained by dividing the transfer function GYY by the transfer function GXY is defined as GCY.

Claim (Index 4):
The signal processor according to  claim 1 , wherein\n the controller further\n transforms the audio signal into frequency band signals F(n), where n denotes an index indicating each frequency band, \n compares, for each frequency band indicated by n, a gain of transfer function GYY(n) with a gain of transfer function GXY(n), \n causes the Y-side speaker to output a sound of one of the frequency band signals F(n) and causes the X-side speaker to output a sound of a signal obtained by processing the one of the frequency band signals F(n) using transfer function GCY(n), when the gain of the transfer function GXY(n) is greater than the gain of the transfer function GYY(n), and \n causes the X-side speaker to output the sound of the one of the frequency band signals F(n) and causes the Y-side speaker to output a sound of a signal obtained by processing the one of the frequency band signals F(n) using transfer function GCX(n), when the gain of the transfer function GYY(n) is greater than the gain of the transfer function GXY(n), \n where for each frequency band indicated by n:\n a transfer function between the Y-side speaker and the Y-side ear is defined as GYY(n); \n a transfer function between the X-side speaker and the Y-side ear is defined as GXY(n); \n a transfer function obtained by dividing the transfer function GYY(n) by the transfer function GXY(n) is defined as GCY(n); and \n a transfer function obtained by dividing the transfer function GXY(n) by the transfer function GYY(n) is defined as GCX(n).
