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 allotted audio) for the
subwoofer driven
low-frequency effects.
