What are the advantages of Dolby Digital Surround AC-3?

Dolby Digital Surround offers discrete processing of 5 independent channels ( Left, Center, Right, Left Surround, Right Surround, and an additional effects channel that may be routed to a subwoofer) of audio information. Dolby Digital Surround provides the producers of movie soundtracks added flexibility and creativity in the studio that results in more realism, and a "you are there experience." Each of the 5 Audio channels is a full range (20-20khz) signal. The discrete nature of Dolby Digital Surround provides increased clarity (especially critical for dialogue) and spatial realism. With Dolby Digital Surround, audio images may be panned across the front of the room; from front to rear; from rear to front; and even diagonally.  more
