Patent ID: 7606711

Claim:
An audio signal processing device, comprising: a subband extracting means for generating a subband signal that expresses a time-varying-strength of a basic frequency composition and a higher harmonic composition of an audio signal of a processing object that expresses a waveform of an audio sound; and a deleting means for generating a deleted subband signal that expresses a result of deleting a portion expressing a time-varying higher harmonic composition of a deleting object that is made corresponding to the audio sound in the subband band signal generated by the subband extracting means, wherein a corresponding relationship between each audio sound made by a specific speaker and the higher harmonic composition of the deleting object made correspond to the audio sound is possessed by the corresponding specific speaker, wherein the deleting means rewritably stores a table that expresses the corresponding relationship and generates the deleted subband signal according to the corresponding relationship that is expressed by the table stored by itself.
