(From Wikipedia, the free Encyclopedia)

ATRAC (Adaptive TRansform Acoustic Coding) is an audio compression algorithm used to store information on Minidiscs, developed by Sony. It uses quadrature mirror filters and modified discrete cosine transform to represent encoded audio.

ATRAC SP

Two stacked QMF split the signal into 3 parts:

No joint stereo encoding.

Data rate is 266 Kb/s

ATRAC LP

Double play time, only mono.

ATRAC-3 LP-2

Three stacked QMF split the signal into 4 parts:

Joint stereo encoding. 132 kbit/s (yes, 15% below ATRAC SP/2)

ATRAC-3 LP-4

Similar to ATRAC-3 LP-2, but 66 kbit/s (half the data rate of ATRAC-3 LP-2). Low quality, similar to MP3 at 80...96 kbit/s.
