The present invention relates to a correcting apparatus of sound signal distortion by way of an audio frequency pass segmentation, the apparatus comprising: frequency band segmentation means for segmenting an audio frequency band sampled by a predetermined frequency into a plurality of bands; decimation means for performing a decimation in respectively different ratios in accordance with a sound data band band-segmented by the frequency band segmentation means; distortion correcting means for performing a distortion correcting on the sound data decimated from the decimation means per band; and data output means for synchronizing the sound data distortion-corrected at the distortion correcting means so that the sound data can be in the same order as the sound data when input to the frequency band segmentation means to thereby b output in synthesis. According to the present invention, the audio frequency band is segmented into a plurality of frequency bands by way of a Bark Scale for illustrating man's sound distinguishing calibre in the audio frequency band, and in the low frequency band the sampling numbers of sound data are increased whereas in the high frequency band, the sampling numbers are decreased.
