Logic Pro Exporting/Bouncing Individual Surround Files

Hi all,

I'm new to Logic Pro. I have two tracks both set to surround, and I've used the surround panner to work out where I want the sound to go on each track. i.e. Track 1 is centered as I want the music to fill the room. Track 2 is at the front only as this is the vocal part. I'm trying to export/bounce the whole thing in Surround 6.1 so that I should have a total of 7 files but for some reason all I get is 2 each time. Where am I going wrong?

iMac (Late 2009), Mac OS X (10.6.4)

ha! i ws just going to suggest this. If you want to listen to what you are doing more reliably, you could probably also jackOSX. A little more setup than soundflower, but a much more powerful tool once you learn it.

H emotionboy
Firstly are you using the master track for the bounce ?
And secondly have you selected the surround bounce before you bounce ? If you want them files to be split you have to select the split files . I do use logic for 5.1 work quite often and I had the same problems the firs time around also 🙂

Hi again emotionboy
If your using multi channel audio files in your project logic automatically should go into surround mode and you should see a multi channel master output fader at the right end of the mixer.
And on the surround master channel , just click bounce on the bottom end of the fader and you will see the bounce preference come up and there you can select interleaved or split bounce make you select wav of aiff cause there is no such thing as a multi channel mp3 . But before all this you should go to your preferences/audio/ i/0 assignments/output and select the preferred surround output mode you want 5.1 ITU 6.1 7.1 . By the way why do you want 6.1 surround files just curious ?

Still not working Yildox.

I want to create DTS ES 6.1- I have DTS Master Audio Suite but there doesn't appear to be a panner so I have to create all 7 channels and then import them into DTS Master Audio Suite.

In Logic Pro I have one track which is in stereo. I'm using the panner to point the sound into the middle so it will fill the room when you listen to it. When I export I need to have them be split into the 7 channels that make up 6.1. I've configured the track to surround. I've gone Preferences/Audio/Surround and selected 6.1 (ES/EX). I've gone Settings/Audio/Surround Format: 6.1 (ES/EX). I've clicked on Bounce in the Master Channel, ticked Surround Bounce, File Type: Split, File Format: Wave (or AIFF- I've tried with both), under Destination PCM is ticked.

Once bounced I end up with 2 files- The track name with L and the track name with R. What I am trying to get is: TrackL, TrackC, TrackR, TrackLFE, TrackLS, TrackS, Track RS - 7 tracks.

Any other thoughts?

Are you sure you have the audio channels output set to surround output ?
Cause you just might be using the bilingual panner by mistake ?
I use logic with surround sessions and use the split audio selection very often and dont have any problem at all.
I have another question for you what is the audio interface your using ? Has it got multiple outputs ?

Hi Yildox, thanks for your help so far.

I have Logic 8.

I'm basically following the instructions for Logic 7 http://www.soundonsound.com/sos/aug06/articles/logictech_0806.htm

Since you've done it before, it would help if you could literally talk it through from scratch. Assume you have a brand new empty project completely not set up for surround sound in any way, no panning no anything. You have a single stereo file. What would you do step by step to put this into Logic Pro and turn it into 6.1?

By the way, I don't yet have any surround speakers attached to my iMac- I will do soon and then monitor the sound more closely, but all I'm interested in knowing now is how to split the files so that when I get some new surround speakers for my iMac I can get straight to work.

Thanks.

Bingo Problem solved 🙂
Logic wont bounce multi format audio files without multiple outputs in your case you need an audio interface that has at least 7 outputs to get 6.1 files . Meaning if you are using the imacs built in sound output you cant bounce in 6.1 you need a audio interface of some kind I am sorry to say 😟 So you are most likely doing the right procedure for surround work but with out the system connected to a multi output interface logic wont give you what you want .

Found this post by Googling the same issue you were having and I'm glad to say I figured out a way around this limitation. What you can do is download the application Soundflower for OS X, link here: http://www.macupdate.com/app/mac/14067/soundflower

Once installed Soundflower gives you the ability to pass audio from one application to another, it acts as faux audio input/output with up to 16 channels. All you need to do is go to Logic's Preferences>Audio and change your ouput to Soundflower (16ch). This will allow you to bounce your surround tracks as multiple files. See attached photo. Hope this helps anyone who runs into the same problem! 🙂
