Dolby Digital AC-3 Audio

There are two good reasons to use AC-3 format audio in your DVD production:

• To take advantage of 5.1 surround audio (five main speakers and a subwoofer—six

channels of audio total), which is supported by AC-3 but not by MPEG-1 Layer 2

• To produce stereo data-compressed audio that is fully compatible with every DVD

player in the NTSC markets of North America and Japan. You may run into some
compatibility issues with older DVD players in PAL countries.

You can use the AC-3 encoder in Compressor to encode everything from stereo to 5.1
surround audio. See

Previewing AC-3 and DTS Audio

for information on listening to

surround audio.
