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

摘要

In the present invention, a waveform correction processing unit (10) corrects the waveform of a first digital sound signal (for example, a CD signal) having a first sampling frequency. A bit-and-sampling-frequency converting unit (50) converts the first digital sound signal with a waveform corrected by a first waveform correction processing unit into a second digital sound signal (for example, a high-resolution digital sound signal) having a second sampling frequency higher than the first sampling frequency. A waveform correction processing unit (20) corrects the waveform of the second digital sound signal.
