Abstract: An audio signal processor includes: a first amplifier that amplifies a first audio content; a mixer that mixes an output signal of the first amplifier and a second audio content; a second amplifier that amplifies an output signal of the mixer; and a setter that sets an amplification amount of the first amplifier. The setter sets an amplification amount in the first amplifier so that the amplification amount in the first amplifier cancels an amplification amount in the second amplifier.

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.
