Adaptive Transform Acoustic Coding (ATRAC) by SONY. |
Adaptive Transform Acoustic Coding (ATRAC) is a family of proprietary audio compression algorithms developed by Sony. MiniDisc was the first commercial product to incorporate ATRAC in 1992. ATRAC allowed a relatively small disc like MiniDisc to have the same running time as CD while storing audio information with minimal loss in perceptible quality. Today ATRAC is used in many Sony-branded audio players. Improvements to the codec in the form of ATRAC3, ATRAC3plus and ATRAC Advanced Lossless followed in 1999, 2002 and 2006 respectively.
Other MiniDisc manufacturers such as Sharp and Panasonic also implemented their own versions of the ATRAC codec. The hybrid lossless compression scheme was added to the ATRAC family in 2006.
ATRAC uses a variety of advanced technologies to analyze digital sound data, allowing it to reduce the size of that data while maintaining superb sound quality (ATRAC*1 compresses music data to approximately 1/5 the data rate of a CD; ATRAC3 and ATRAC3plus are able to compress music data to approximately 1/10 and 1/20 the data rate of a CD, respectively). This ability to reduce the size of data has enabled recording media to be made smaller and more tracks to be recorded on them, changing the way we listen to music.
Developed by Sony Corporation
Sony’s original ATRAC*1 has continued to change the way we listen to music, evolving into ATRAC3, ATRAC3plus and ATRAC Advanced Lossless.
ATRAC is the collective name of all these audio compression technologies.
