To study the difference of hearing impression among several high sampling digital recording formats, we conducted subjective evaluation tests of perceptual discrimination among following digital recording formats: 48kHz 24bit PCM, 192kHz 24bit PCM and DSD. Sound stimuli for the evaluation were originally recorded to maintain the exact same quality of analog input feeds to the three A/D conversion systems. The sound reproduction system for the subjective evaluation tests was also carefully designed to reproduce the original quality of each digital recording format. Listening panels were selected from students and faculty stuffs of university of music, recording engineers, and musicians. A pair test method was applied to the subjective evaluation. Through the several evaluation tests, no significant difference was observed.
