hi greg
dolby suround is a suround system that is stereo compatible. it used
to be the standard for cinemas. it works in the way that signals
embedded in the stereo mix that are out of phase are forced out of
the suround channels - giving you the ability to "space things out".
When you do your mix you encode it with hardware from dolby (i bet
you can get pluins theese days, which will do the job for you - i can
ask my coleage if your interested.) and you end up with a stereo
signal. when the mix is played back, you decode it (e.g. dvdplayers
has the decoder built in) and you get your suround mix
when you mix 5.1 in logic you are mixing 6 discrete channels. this
will never be stereo compatible - unless you convert it to dolby
suround (which again i guess you can get plugins to do for you.)

Hello All,
I'm attempting to mix down 15 tracks into Dolby 5.1 Surround Sound
using
Logic Pro 7.2.3. The panning is all set and I can bounce the
tracks, but the
result of bouncing is two aiff files labled "[title]-L" and
"[title]-R". I
found a Dolby Labs publication that descibes these as the two-channel
mix-down of a 5.1 format. However, the publication says that these
can be
decoded into 5.1 audio: how does this work?
My question is this: are these two audio files all that is needed to
playback my composition in 5.1 Surround? Do I have to make a final
mix of
the two files to get one 5.1 compatible audio file, if so how do I
do that?
Obviously, this is my first attempt at Surround Sound mixing. Any
advice is
greatly appreciated.
Thanks,
-greg d.
