dts audio

The DTS Audio CD or Multichannel Music Disc is an audio Compact Disc that contains music in surround sound format. It is a predecessor of DVD Audio.

Where regular CDs store the music as linear PCM, the DTS-CD stores music using the DTS format, with the same fixed bitrate as 16-bit linear PCM, namely 1,411,200 bit/s or roughly 1,378 Kib/s.

As opposed to other surround formats, such as Super Audio CD and DVD-Audio, which require a specialized player, a DTS-CD is compatible with most standard CD and DVD players with a digital (S/PDIF) output.

These players will recognize the disk as a standard audio CD. The only requirement is an audio processor, usually a receiver that can decode the DTS audio stream.

Available surround content variations include 5.1, 5.1 ES, and 6.1 ES, each with or without the optional LFE channel.
