What is OMA?
A file with the OMA file extension is a Sony OpenMG Music Format file. Files in ATRAC3 (Adaptive TRansform Acoustic Coding3) An audio compression technology from Sony that provides multiple compression ratios depending on desired sound quality. At 132 Kbps, the music can be compressed to approximately 10% of the space used by a CD. Introduced on the MiniDisc in 1993, the original ATRAC format provided near CD quality sound, but ATRAC3, introduced in 1999, rivals the CD. ATRAC compression is 5:1; ATRAC3 is 10:1.

ATRAC3plus In 2002, Sony introduced ATRAC3plus, which provides a 20:1 compression ratio, bringing the data down to 5% of the original CD. It can achieve very high quality sound at 48 and 64 Kbps or be practically indistinguishable from the original at 256 Kbps. The CD data rate is 1,411 Kbps.

What is AAC?
Advanced Audio Coding (AAC) is a standardized, lossy compression and encoding scheme for digital audio. Designed to be the successor of the MP3 format, AAC generally achieves better sound quality than MP3 at many bit rates.

AAC has been standardized by ISO and IEC, as part of the MPEG-2 & MPEG-4 specifications. The MPEG-2 standard contains several audio coding methods, including the MP3 coding scheme. AAC is able to include 48 full-bandwidth (up to 96 kHz) audio channels in one stream plus 15 low frequency enhancement (LFE, limited to 120 Hz) channels and up to 15 data streams. AAC is able to achieve indistinguishable audio quality at data rates of 320 kbit/s (64kbit/s/channel) for five channels. The quality is close to CD also at 96 kbit/s (48kbit/s/channel) for stereo.

AAC's best known use is as the default audio format of Apple's iPhone, iPod, iTunes, and the format used for all iTunes Store audio (with extensions for proprietary digital rights management).

AAC is also the standard audio format for Sony's PlayStation 3 and is supported by Sony's Playstation Portable, latest generation of Sony Walkman, Sony Ericsson Walkman Phone, Nintendo's Wii (with the Photo Channel 1.1 update installed for Wii consoles purchased before late 2007) and the MPEG-4 video standard. HE-AAC is part of digital radio standards like DAB+ and Digital Radio Mondiale.
