The workflow I used:

Import the wav files in a multichannel session of Audition.
Export as one interleaved 6-channel wave file
Import the interleaved file in Premiere Pro 2 or 3
Create an empty surround track in the timeline and put the interleaved file on this track.
Export the sound for the DVD as follows: File>Export>Adobe Media Encoder
Export settings: MPEG2, export video not selected, export audio selected.
Audio tab: Dolby digital, codec: surcode for dolby digital
(You can use surcode 3 times for free.)
The 5.1 audiotrack will be converted to an AC-3 surround file for DVD.
Add this file to the MPEG2 video in Adobe Encore DVD.

Good luck

Also, don’t forget to include 2 seconds of silence at the beginning of your tracks, as pointed out elsewhere on CreativeCOW. This is a limitation of AC3 files, but is necessary for set-top players to be able to play the audio from the beginning.

Hi Phocas,

When importing the music or wave files as multichannel session, must you have more than one track of files? For instance if I have a wedding DVD with mostly music must I place each music file on individual tracks if I want certain scores to play just from the rear speakers for instance? If I have sound effects, I can see placing these on separate tracks and directing to certain speakers. I had always put all the music on the Premier timeline and then imported the entire sound timeline to Audition on one track to encode into Dolby 5.1. I have never been able to get the sounds from the correct speakers in 5.1.

Thanks for any help or tips you can offer, Phocas.

Hello George,

In Adobe Audition you have to assign each track to a certain loudspeaker. For example:
Track 1 to front left
Track 2 to front right
Track 3 to rear left
Track 4 to rear right
If the music should come from the rear speakers, you have to put this music on track 3 and 4. Track 3 panned to left and track 4 panned to right.
If you have also soundeffects you can put these on track 5 and higher and assign these tracks each to one of the 4 loudspeakers.

To assign the tracks to the loudspeakers: View>Multichannel decoder.
On the left side of the Multichannel decoder you have the track list. The blue cirkel is the surround planner.
Select in the track list one of the tracks and move the white dot to one of the loudspeakers. Do that for all tracks.
Then click on Export in the Multichannel Encoder window and select “Export as one interleaved 6 channel wave file” and import this in Premiere to put on a 5.1 track.

I hope this helps you.

Good luck
