Wat is een AA3-bestand?
An AA3 file is an audio file compressed with Sony's ATRAC (Adaptive Transform Acoustic Coding) compression technology. It contains a music track in a quality similar to CD audio and does not include any copy protection or digital rights management (DRM). Sony ceased ATRAC in 2008, but several audio players, including MAGIX Sound Forge and Sony ACID Xpress, still support AA3 files.
Meer informatie
Sony developed the ATRAC compression algorithms and released them in 1992. ATRAC first appeared in the MiniDisc data storage format (a format meant to replace the cassette tape, but the CD quickly surpassed it).
ATRAC underwent several updates throughout the 1990s and 2000s. However, few audio players or devices adopted the format outside of Sony audio devices (like the Walkman) and Sony's discontinued Connect Music Store. Sony eventually ended the development of ATRAC codecs in 2008.
OPMERKING: Audio files compressed with ATRAC compression often bear the .aa3 file extension, but they may also be saved in the OpenMG Audio container with the .oma (.OMA file) or .omg (.OMG file) file extensions. Additionally, .AT3 files use the ATRAC3 codec.
