AC3 - Dolby Digital AC-3 Audio
Dolby Digital, or AC-3, is the common version containing up to six discrete
channels of sound. The most elaborate mode in common usage involves five channels
for normal-range speakers (20 Hz - 20,000 Hz) (right front, center, left front,
right rear and left rear) and one channel (20 Hz - 120 Hz) for the subwoofer driven
low-frequency effects. Mono and stereo modes are also supported. AC-3 supports
audio sample-rates up to 48kHz. Batman Returns was the first film to use Dolby
Digital technology when it premiered in theaters in Summer 1992. The LaserDisc
version of Clear and Present Danger featured the first Home theater Dolby Digital
mix in 1995.
