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 ASF?
Advanced Systems Format (formerly Advanced Streaming Format, Active Streaming Format) is Microsoft's proprietary digital audio/digital video container format, especially meant for streaming media. ASF is part of the Windows Media framework.

ASF is based on serialized objects which are essentially byte sequences identified by a GUID marker.

The format does not specify how (i.e. with which codec) the video or audio should be encoded; it just specifies the structure of the video/audio stream. This is similar to the function performed by the QuickTime, AVI, or Ogg container formats. One of the objectives of ASF was to support playback from digital media servers, HTTP servers, and local storage devices such as hard disk drives.

The most common filetypes contained within an ASF file are Windows Media Audio (WMA) and Windows Media Video (WMV). Note that the file extension abbreviations are different from the codecs which have the same name. Files containing only WMA audio can be named using a .WMA extension, and files of audio and video content may have the extension .WMV. Both may use the .ASF extension if desired.

ASF files can also contain objects representing metadata, such as the artist, title, album and genre for an audio track, or the director of a video track, much like the ID3 tags of MP3 files. It supports scalable media types and stream prioritization; as such, it is a format optimized for streaming.

The ASF container provides the framework for digital rights management in Windows Media Audio and Windows Media Video. An analysis of an older scheme used in WMA reveals that it is using a combination of elliptic curve cryptography key exchange, DES block cipher, a custom block cipher, RC4 stream cipher and the SHA-1 hashing function.

ASF container-based media is usually streamed on the internet either through the MMS protocol or the RTSP protocol.
