PROBLEM TO BE SOLVED: To allow for generation of an appropriate sound field in a headphone.SOLUTION: An audio signal processor 100 acquires the headphone characteristics from the audio signal output section 51 of a headphone 50 to a sound receiving point in an ear canal in a headphone characteristics acquiring section 21, generates a reverse filter of the headphone characteristics thus acquired in a reverse filter generating section 22, corrects the phase characteristics of the reverse filter thus generated to become linear phase characteristics in an audio signal output section in a phase characteristics processing section 23, convolves the characteristics of the reverse filter subjected to phase correction in an audio signal inputted from an input section 10 in a convolving section 31, and outputs the audio signal into which the characteristics of the reverse filter are convolved from an output section 40. |
