Open OMA File

File extension OMA is used to identify audio files created through Sony OpenMG Music Format. OMA files are encrypted and conform to the Adaptive Transform Acoustic Coding (ATRAC) format, a proprietary audio compression designed and used by Sony. OMA extension is similar to OMG extension which was also developed by the same manufacturer. Files using this extension can be opened on operating system platforms including Windows, Mac, and Linux.

The popularity of ATRAC gave Sony an edge with its technology. Several Sony products including the MiniDisk, popularized and sold to the public beginning January of 1992, are using ATRAC compression to hold encrypted data.

OMA files were used to be accessed through Sony's online music store popularly known as CONNECT Music Store. Despite the success it gathered from millions of users in US and Europe, the service was discontinued last March 31, 2008. In line with the closing of Connect Music Store, Sony launched a newer site named bandit.fm.

OMA are protected files provided through Digital rights management (DRM) by Sony. DRM provides limitation to the use of the product by devices with no copyright protection imposed. However, there are several applications designed and sold on the market that defeat this purpose. These applications remove DRM restrictions making a product available for unauthorized replication thereby breaching its copyright.

There are plenty of applications developed to convert OMA files into other formats such as File extension MP3, File extension WAV, File extension WMA, and File extension AAC. WMAConvert is among the most popular application used in converting OMA files in to several formats. It can be installed on a Windows environment. This is among the other applications that are designed to remove DRM protection on encrypted files. Once converted, files will be applicable for use on players not implementing DRM restrictions.

Native Sony applications and devices can open and process OMA files. This includes the SonicStage whose later version was designed to remove the DRM protection on some files. However, license copies are excluded for such process preserving their copyrights. Other products include Blaze Media Pro, and Sony SonicStage.
