A Compact Disc player (often written as compact disc player), or CD player, is an electronic device which plays audio Compact Discs. CD players are often installed into home stereo systems, car audio systems, and personal computers. They are also manufactured as portable devices. Modern units support other formats in addition to CDs; such as DVDs, CD-ROMs with audio files and video CDs. DJs often use players with adjustable playback sampling rate to alter the pitch of the music programme. Many modern CD players also include the capability to play MP3 CDs. CD playback functionality is also available on all modern CD-ROM/DVD-ROM drive equipped computers as well as on DVD players and CD-ROM/DVD-ROM based game consoles.
