Abstract

A data reproduction apparatus includes: arithmetic means for calculating difference data that indicate a difference between left-channel and right-channel data that have been compressed in a predetermined compression format; higher harmonic component generation means for generating a higher harmonic component, which was lost during compression, by performing, when the difference data's signal level exceeds a predetermined threshold, a digital limiter process that suppresses the signal level to the threshold; and adding means for adding the higher harmonic component to the left-channel and right-channel data to reproduce original data before being compressed.
