Adaptive TRansform Acoustic Coding
<algorithm> (ATRAC) An audio compression algorithm, introduced by Sony
for its Mini Disk, which relies on the masking of low-amplitude frequency
components by temporaly adjacent high-amplitude components. ATRAC consists of a
three-band subband encoder (0...5.5, 5.5...11, 11...22 kHz) and a MDCT based
transformation encoder.
