<P>PROBLEM TO BE SOLVED: To provide a digital audio signal processing device that suppresses noise generated at signal clipping when reproducing digital audio signals beyond a dynamic range. <P>SOLUTION: The digital audio signal processing device includes: a processing region calculation section for allocating digital audio signals to a plurality of processing regions; a peak detection section for calculating a peak value of amplitude of the digital audio signals; a processing region management section for calculating a first processing region of the plurality of processing regions which includes a digital audio signal whose peak value is larger than a predetermined threshold, and calculating a first correction value for the digital audio signals included in the first processing region; and a suppressed waveform generation section for outputting the digital audio signals included in the first processing region through suppression using the first correction value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
