Audio codec offering close to CD-quality sound. It's used for MDLP recording with some MiniDisc recorders, for music storage in some portable memory players, and in Internet music applications such as Liquid Audio and RealAudio.
Sony's audio codec used by MDLP MiniDisc players and Sony portable players. It allows twice the data compression of ATRAC.
ATRAC3 is Sony's new digital data compression format. It stands for Adaptive TRansform Acoustic Coding. ATRAC made its debut in 1992 with MiniDisc. The latest ATRAC3 roughly doubles the data compression capability of ATRAC, making it possible to now record up to 320 minutes of music on a single MiniDisc or 4 hours of music on a 128MB Memory Stick.
The audio codec used by MDLP MiniDisc players and Sony MP3 players.
is a newer data compression technology that allows more audio to be stored on a MiniDisc. ATRAC3 recordings are also called MDLP (MiniDisc Long Play) recordings. In LP2 mode, you can record twice as much audio as would normally fit on an MD; in LP4 mode, you can record four times as much. Both modes record in stereo. Since ATRAC3 uses more compression than ATRAC, the sound quality of MDLP recordings is slightly lower than that of standard ATRAC recordings, and LP2 recordings sound better than LP4. Non-MDLP-capable players cannot play back MDLP (ATRAC3) recordings.
A compressed audio format used by MDLP MiniDisc players and Sony MP3 players. This is the successor to ATRAC.
is a newer version of this codec that squeezes music into even smaller files. It's used for MDLP recording with some MiniDisc recorders, for music storage in some portable memory players, and in other Internet music applications like Liquid Audio and RealAudio. A MiniDisc recorder with MDLP gives you a range of compression options (in order of increasing compression): regular recording mode - standard ATRAC codec (292 Kbps encoding bitrate) LP2 mode - ATRAC3 codec (132 Kbps encoding bitrate) LP4 mode - ATRAC3 codec (66 Kbps encoding bitrate)
An audio codec made by sony that is comparable to mp3.
