Surround What and how to listen to DVD-Audio, DTS-CD discs? multichannel music
DTS CDs are encoded in 5.1 surround sound using the DTS compression algorithm. As such, the fidelity is of lower quality than the sound quality offered by CDs, DVD-Audio discs, and SACDs. DTS CDs are not encoded in stereo. You can play DTS CDs in three ways:
* On a CD player connected to a 5.1-channel receiver or pre/pro with a DTS decoder via an optical or coaxial digital cable.
* On a DVD-Video player with the "DTS Digital Out" logo on the front panel (meaning any player available today) to a 5.1-channel receiver or pre/pro with a DTS decoder via an optical or coaxial digital cable.
* On a DVD-Video player with a built-in DTS decoder connected to a 5.1-channel receiver or pre/pro via the 5.1-channel outputs (i.e., six RCA cables).
The DVD-Audio format offers the capability of stereo and surround sound (5.1) playback at higher resolution than the CD (and therefore, higher resolution than DTS too). DVD-Audio uses PCM as the encoding algorithm like the CD, but while the CD is limited to encoding in 16-bit/44.1-kHz PCM, DVD-Audio can offer up to 24/192 in stereo and 24/96 in surround sound. In practice, the wordlength (the number of bits per pulse) on DVD-Audio discs can vary, though a 24-bit word is far and away the most prevalent. However, the sampling rate (in kHz) varies widely on DVD-Audio discs. In most cases, stereo tracks are presented in 24/96, but some discs are encoded 24/88.2 or 24/48, and some are encoded at the maximum 24/192. Most surround-sound tracks are encoded at 24/96.
The vast majority of DVD-Audio discs offer a high-resolution surround-sound track, and some also offer a high-resolution stereo track as well. Most discs also have DVD-Video-compatible Dolby Digital and/or DTS surround-sound tracks as well.
Note that to play DVD-Audio tracks, you must have a DVD-Audio player. Some are available through www.crutchfield.com , Best Buy, and Circuit City. Again, with a DVD-Video player, you can play Dolby Digital or DTS tracks that may be encoded on a DVD-Audio disc.
