<P>PROBLEM TO BE SOLVED: To provide an audio processing unit capable of outputting satisfactory audio. <P>SOLUTION: The audio processing unit is provided with a coefficient multiplier 210 for attenuating an audio signal input from an input section, by a predetermined level value B; a signal process processor 220 for generating an effect signal by executing predetermined filter processing on the input audio signal; a correction signal generation means 240 for generating a correction signal to correct the above effect signal, so that the level value of the effect signal is included in a value obtained by subtracting the level value B attenuated in the coefficient multiplier 210 from 1 of a reference value; a level adjuster 250 for adjusting the level value of the effect signal, based on the correction signal output from the correction signal generation means 240; and an adder 260 for adding the corrected effect signal of which level is adjusted in the level adjuster 250, and the input audio signal attenuated with its level by a coefficient multiplier 210 so as to output to an output means 300. <P>COPYRIGHT: (C)2008,JPO&INPIT |
