The DTS-CD, DTS Audio CD or 5.1 Music Disc (official name) is an audio Compact Disc that contains music in surround sound format. It is a predecessor of DVD Audio. Technically, it conforms to the Red Book standard, except for the way the music is encoded on the CD. Where regular CD's store the music as linear PCM, the DTS-CD stores music using the DTS format.

As opposed to other surround formats, such as SACD and DVD audio, which usually requires a specialized player, a DTS-CD is compatible with most, if not all, standard CD players with a digital (S/PDIF) output, only requiring a receiver that can decode DTS tracks.
