Whats the difference between MP3 and other audio file formats?
MP3 is an encoding format that compresses the size of an audio file so that more files can be stored on Portable Music Players with little reduction in the quality of the sound recording. MP3 was one of the first encoding formats to be developed, and the term is used as a general term to describe digital music, and digital music players in general. Modern Portable Music Players tend to play both MP3 and WMA file formats.
