|Description||Developed by the Signal Processing Group at Microsoft, the WMA file format is part of the Windows Media framework and was first released commercially in 1999, with support for playback of WMA encoded files as part of Windows Media Player. Creation of WMA files did not come until Windows Media Player version 7. The original codec was targeted as a direct competitor to the MP3 and RealAudio formats, and has achieved a broad level of adoption thanks to support for playback on numerous DVD players, Nokia mobile handsets and Playstation portable devices.|

|Technical Details||In almost all circumstances WMA files are part of the Advanced Systems Format (ASF) container, a proprietary container format developed by Microsoft for both digital video and digital audio. Every WMA file contains an audio track encoded in one of four mutually distinct codecs - WMA, WMA Voice, WMA Lossless or WMA Pro - WMA is the most commonly found of the four, but is a lossy codec, with the ability to encode audio signals sampled at up to 48 kHz. WMA Pro is an improved version, allowing sampling up to 96 kHz, but has achieved little hardware and software support. WMA Lossless is designed to compress audio signals with no loss of quality from the original source (up to 96 kHz) and is used in some Windows Mobile devices as well as the Logitech Squeezebox Touch. Finally, WMA Voice is a lossy codec optimized for low-bandwith voice playback applications, with mono sampling support up to 22.05 kHz - it is perhaps most well known for being used by the BBC World service for streaming Internet radio.|

|Technical Details||MPEG-4 Part 14 or MP4, formally ISO/IEC 14496-14:2003, is a multimedia container format standard specified as a part of MPEG-4. It is most commonly used to store digital video and digital audio streams, especially those defined by MPEG, but can also be used to store other data such as subtitles and still images. Like most modern container formats, MPEG-4 Part 14 allows streaming over the Internet. A separate hint track is used to include streaming information in the file. The only official filename extension for MPEG-4 Part 14 files is .mp4.|
