Determine in detail about MP3 (MPEG-3)

MPEG-3 uses an audio compression technology; it compresses CD-quality sound by a factor of about 10 while retaining most of the quality for example a 60 Mbyte CD track is turned into a 6 Mbyte MP3 file. Music data is generally stored on an MP3 player that plugs into the computer via a USB port. Music data is downloaded to the MP3 player where it's stored in a file. Player has its own internal battery which enables a user to listen to the music files through personal head phones or connect the player to an external sound amplification unit. Variations of MP3 players (for example I-pods) exist which use their own file structures when storing music; these require compatible software to allow files to be stored in correct format.
