Description🔵 The OMA (Open Mobile Alliance) format is a container file format used for storing multimedia content, such as audio or video, on mobile devices. It is primarily associated with digital rights management (DRM) protected content distributed by online music stores and streaming services. OMA files typically have extensions like .oma, .omg, or .dcf. OMA files use a combination of audio and video codecs, encryption, and DRM technologies to protect copyrighted content from unauthorized copying and distribution. These files are designed for playback on mobile devices compatible with OMA DRM, ensuring that only authorized users with valid licenses can access and play the content. OMA files may require specialized software or mobile applications for playback, as they may not be supported by all media players or devices.
Technical details🔵 The OMA format is a container format used to encapsulate multimedia content, including audio, video, and images. It is designed to support DRM protection, allowing content providers to control access to and usage of their digital media. The OMA format itself does not specify a particular codec for audio encoding. Instead, it can encapsulate audio data encoded using various codecs, such as AAC, MP3, or WMA. This allows for flexibility in supporting different audio compression formats. One of the primary purposes of the OMA format is to enable DRM protection for multimedia content. DRM mechanisms embedded within OMA files control access to the content and enforce usage restrictions, such as limiting the number of times the content can be played or preventing unauthorized copying and redistribution. OMA DRM-protected files typically include a rights object, which contains metadata and cryptographic keys used to enforce DRM policies. The rights object specifies the conditions under which the content can be accessed, including information about the user's rights, permissions, and entitlements.

A format of audio stream coding deployed by Microsoft in 1999, it has been serving as a foundation for Windows Media. Its purpose is to store and distribute audio content. Firstly, it was considered a real alternative for MP3, but then, when ACC appeared, WMA partially lost its significance. It differs fundamentally from MP3 by one realization and can be installed on an equal basis with other system codecs of Windows 9x.

A good compression quality characterizes WMA, and therefore it has been adapted later for many audio players, mobile devices, and Playstations. However, due to excessive closure, files in this format cannot be played back on other platforms with satisfactory quality. The new version allows for multi-channel coding of large audio files and coding of voice data. In addition to that, the delay in coding has been significantly diminished thanks to the technology of reduced time dilation.

Technical details🔵

The name of WMA is being used simultaneously for the file format and the codec. There are some types of the format:

  • WMA, a close analog for MP3;
  • WMA Pro, high-quality sound files with a wide range of channels;
  • WMA Lossless, for lossless compression;
  • WMA Voice, for compression of voice content into low bitrate files.

According to Microsoft programmers, an audio file of 64 Kbit/s bitrate has a similar sound clarity as the tracks from the original CD. However, some of advanced users do not share such views. Most often, WMA files are generated in Advanced Systems Format which contains both audio and video content. One of the failures is the impossibility to support bitrate of more than 160Kbit/s.
