DIGITAL SOUND PROCESSING DEVICE, DIGITAL SOUND PROCESSING METHOD, DIGITAL SOUND PROCESSING PROGRAM

摘要

A waveform correction processor (10) corrects the waveform of a first digital audio signal (a CD signal, for example) having a first sampling frequency. A bit depth and sampling frequency converter (50) converts the first digital audio signal with the waveform corrected by the first waveform correction processor to a second digital audio signal (a high-resolution digital audio signal, for example) having a second sampling frequency, which is higher than the first sampling frequency. The waveform correction processor (20) corrects the waveform of the second digital audio signal.
