How to create a 5.1 surround audio file...I hope this workflow is accurate
This should clear the room...:-)
Just to get this all accurate...you DO NOT need to create surround audio filesin Logic,
to create surround sound in FCPX.
FCPX has qute a nice surround editing interface.
BUT a multiple ins and outs audio interface e.g MOTU 828, is necessary.
A simple experiment looks like this: (other audio interfaces will be similar)
Fire up the Motu Audio Setup app. see img
Open Mac System prefs > Sound , select Motu for Input and Output
Start a new project, check project properties are surround and 48khz
Add some footage to the timeline, with or without sound is ok.
Add at least 6 fx sounds from FCPX sound library one with heavy bass effects is good for LFE test.
Select each sound and change the Surround Panner parameter to Circle
(other presets worth experimenting with, e.g. ambience etc.)
Grab the grey dot in the panner and move it, the sound will move around in your speaker system.
The panner will be coloured if it is anywhere other than in front of one speaker icon i.e. exclusively thru one of the speakers
thats it...so easy and plenty of parameters to play with
I know the issue has been solved but I also was looking for a way to monitor 5.1 from FCP X.
As I'm not planning on spending anywhere near a 1000 bucks, and only need USB -> 6 x analog out, I found this nifty little cheap thing: http://www.esi-audio.com/products/gigaporthd/
The specs aren't half bad and I think this would do the trick nicely as I already have a surround amp with 5.1 analog inputs (DENON AVR3311). It also is compatible with Mac core audio, so no drivers needed.
If I'm not mistaken, you can assign channels to outputs in the MIDI/Audio configuration app on your mac.
Haven't tried it yet, but will let you know once I do.
Hope this also helped
