AB  - ATRAC is an audio coding system based on psychoacoustic principles. The input signal is divided into three sub-bands which are then transformed into the frequency domain using a variable block length. Transform coefficients are grouped into nonuniform bands to reflect the human auditory system, and then quantized on the basis of dynamic sensitivity and masking characteristics. ATRAC compresses Compact Disc audio to approximately one-fifth of the original data with virtually no loss in sound quality.
