 The difference between the prints that had DTS and those that didn't was like seeing a completely different movie."

Dolby Stereo...
Dolby Stereo is a four track analog sound format. It has Left, Center and Right channels behind the screen and one common Surround channel behind and to the side of the audience. However, since conventional film can carry only two tracks of optical sound information, the four Dolby Stereo tracks are encoded into two tracks by a processor in the mixing studio. These two tracks are read by the Dolby Stereo processor in the theatre and converted once again into four tracks. Naturally, this process of extracting the four original tracks out of the two encoded tracks can never be perfect. The analog tracks on the film print are also capable of only a certain amount of loudness and soft sounds may be lost in the noise of the optical track.
 ...and DTS
DTS is a digital sound format with six channels. Apart from the Left, Center and Right channels, DTS also has Left and Right Surround channels and adds a separate Sub-woofer channel. In DTS, these six tracks are maintained discretely and thus, there is complete separation between them. There is also a much greater dynamic range in the sounds as they are digitally reproduced.
Finally, there is absolutely no wear and tear on the CD-ROM discs that carry the actual sound track and they remain perfect throughout the life of the print and after. Apart from the big dramatic sound effects that digital offers, it also allows clearer positioning of individual sounds, cleaner dialogues, more realistic sound effects and more accurate music reproduction. |
