5.1 audio separate channel extraction
on Jan 22, 2017 at 10:07:52 am

Hi guys,

I really need someone to give me a solution about this simple issue which wasted a lot of my time seeking for it with no resolution.

I am working on a movie project for a movie theater and about to create a DCP version of the movie using OpenDCP application, I found it very easy to deal with and also it is free.

I am facing a simple issue which has stopped me from creating the DCP which is the separate 5.1 wav files the OpenDCP asking for to render the DCP, the program requires having 6 separate wav files as 1 wav for each FR, FL, C, SUB, RR and RL speakers.

I am using Adobe Audition and Premiere but I couldn't find any direct or correct way to have those channels exported similar as they say in FCP you can simple select those channels at the export window and have them ready. hence in audition or premiere when you export channels the program will deal with "channel" as timeline not as speakers channel.

Kindly advice me and I will be so thankfull

regards
Firas

for DCP exports.

New custom sequence, with multichannel mono audio tracks (6 total)
important you choose multichannel and NOT 5.1...for some reason it lowers the audio volume on export.

Then bring in each track in order of smpte specs:

L
R
C
Lfe
Ls
Rs

Then go to the mixer window and pan each track.
L
R
L
R
L
R

Also make sure you check each box (in the mixer) that indicates
L & R is mapped to1 & 2
C & Lfe is mapped to 3 & 4
Ls & Rs is mapped to 5 & 6
(this keeps them all seperated without combining them all)

Export the quicktime, in the audio options choose multichannel 24-bit.

If you take the 5.1 audio file into Audition, use Edit > Extract Channels to Mono Files... to easily separate each channel to a unique file, labeled with the channel label from each track.

Durin,

I think that Firas is looking for the proper procedure to export six separate/split/discrete tracks from Audition so he can take them into DCP as such.
What he was experiencing, to my understanding, is that Audition exported a single surround track as the only option.
I wanted to help and tried to do that in Audition, which I have previously only used to clean noisy tracks, but all I got was the same result as I think Firas got.
Firas surely found a solution in order to move on. But I didn't! ☺
I can't believe that it is not possible in Audition.
From Logic I export split files resulting in six separate files L,R, C, LFE, Ls, Rs, but to test Firas' situation, I imported them into Audition, multitrack 5.1, each panned to their respective corner and LFE as such with all coming out perfectly through my surround audio monitoring system, just like in Logic, but in Audition, I can only export a single surround file.

So now I am super curious and was not able to find anything about it online, not even through Lynda.com's tutorials.
I am on CS6. Does this limit the export of six split tracks L,R, C, LFE, Ls, Rs to a single surround track or is there a way to export six split tracks?

Thanks in advance,
Alex
