The DTS-CD (also 5.1 Music Disc) is an audio CD on the up to 5.1 channels of DTS encoded can be stored. A similar process is possible with AC3 content (AC3 CD).

Construction

DTS has the same bit rate of an audio CD to be exactly 1.4112 million bit / s Thus, it can be read by regular CD players. These can usually decode only PCM, so that a DTS -capable AV receiver eg via S / PDIF must be connected to the player. Most DTS -capable DVD player supported by the correct reproduction of the house. Thus, up to 80 minutes 5.1 music can be stored on a CD.

Production

Up to 6 individual mono wave files can, for example, CD Pro DTS convert to a 5.1 -Wave file with the fee-based tool SurCode. Then they can be burned as an audio CD as ordinary PCM audio files.

Dissemination

Commercially, the DTS-CD is almost not sold because DVD-Audio allows you to select between multiple audio tracks. The cinema coming to use CDs with DTS movie sound differ in their structure for DTS CDs ( APT -X100 compression).

Playback on computers

On the computer, DTS wave files can be played correctly by only a few programs. As an example of the VLC media player supports most DTS files. Another possibility is the direct output, for example, via S / PDIF or HDMI to an external decoder (AV receiver ).

Benefits

  • Unlike other surround sound formats such as Super Audio CD or DVD-Audio, the separate players need the DTS-CD with most CD players is compatible and only requires a CD player with digital output and a DTS decoder, which nowadays is already integrated into most home theater systems.
  • Compared to multi-channel sound, which is encoded in stereo matrix, and a matrix decoder (such as Dolby Pro Logic, DTS NEO: 6) is decoded, the DTS-CD provides surround sound without any loss in quality.
  • DTS CDs are Red Book compliant, ie " normal" audio CDs manageable.

Disadvantages

  • When the DTS-CD can be played in regular CD players, only hear a noise. In some cases, speakers may be damaged by this at high volume.
  • Not all systems with DTS decoders support the correct reproduction, especially for car radios with DVD playback support, there can be problems.
  • DTS encoder programs are expensive to buy, so that the natural production is more difficult than with AC-3 CDs.
  • DTS was the late 1990s, a little more widespread than Dolby AC -3 ( Dolby Digital termed today ), but now dts plays hardly any role in the consumer market.
  • Crossfading, dithering and equalizing the DTS raw data only in case of prior decode possible, leads to loss of quality.
