MP3

MPEG Layer 3. The data required for an MP3-encoded audio track is 12 times less than that of the same track recorded at standard CD quality. Hence MP3 requires shorter download times if used to transfer music via the Internet for example, and less storage space, giving rise to a proliferation of solid-state MP3 players such as the Apple iPod and players in mobile phones. MP3 files can be stored on any digital recording medium. Provided they have MP3 decoding capabilities, CD and DVD players can read a CD that has been burned with MP3 tracks.
