Those people who have Sony devices might be well aware of OMA file format. OMA file format is not a common audio file format nowadays. Some OMA audio files are even DRM protected. All of these have resulted in a question: it seems we are unable to play OMA audio files on non-Sony devices since OMA is not widely accepted as that of MP3. Hence there is an urgent need for converting OMA files for unlimited playback. In this guide, we would like to show you how to convert OMA file to MP3 format in different ways.
Part 1: What is OMA file
Before we learn how to convert OMA audio files to MP3 format, we could firstly go deep into OMA file format. What is OMA file format? AKA Sony OpenMG music, developed by Sony, OMA file is a music file and it is proprietary to Sony. OMA files are saved in the Sony ATRAC (Adaptive Transform Acoustic Coding) format. The OMA file sometimes includes DRM copy protection to prevent people from playing OMA music files that are specific to Sony devices from being played on devices or computers that are unauthorized. Therefore people have to convert OMA files to a different file type before they could play OMA files on other devices or players, generally MP3.
The OMA file type was primarily used to distribute music for Sony, therefore primarily only Sony devices or service (like Sony CONNECT Music Store) could play back OMA files. However, this service was discontinued in early 2008 and the OMA file extension is currently not used for any other file. If you don’t have the original device you used to create or listen to the OMA files, try to convert OMA files to MP3 or other audio file formats.
