<P>PROBLEM TO BE SOLVED: To provide an audio signal processing unit capable of faithfully generating audio signal to original sound, by accurately generating harmonic components from the original audio signal. <P>SOLUTION: This audio signal processing unit has a mixing section 21 which squares the audio signal, a high-pass filter 22 which attenuates the audible band components of the signal generated by the mixing section 21, and an addition section 11 which adds a signal that has passed through the high-pass filter 22 to the audio signal. <P>COPYRIGHT: (C)2007,JPO&INPIT |
