MP3 Players

An MP3 player or Digital Audio Player is an electronic device that can play digital audio files. It is a type of Portable Media Player. The term 'MP3 player' is a misnomer, as most players play more than the MP3 file format.

Since the MP3 format is widely used, almost all players can play that format. In addition, there are many other digital audio formats. Some formats are proprietary, such as Windows Media Audio (WMA), and Advanced Audio Coding (AAC). Some of these formats also may incorporate digital rights management (DRM), such as WMA DRM, which are often part of paid download sites. Other formats are patent-free or otherwise open, such as MP3, Vorbis, FLAC, and Speex (the latter three part of the Ogg open multimedia project).
