I am going to pre-emp the next question by describing something that most will gladly ignore:
How to create a 5.1 surround audio file...I hope this workflow is accurate
This should clear the room...:-)
Creating 5.1 Audio for surround sound is mostly about getting to grips with Logic Pro…not for the faint hearted.
Bringing the mixed bounced audio into FCPX is the easy bit at the end…
Another approach may be to bring 6 tracks into FCPX and do the mix there…
but I have never tried it so I will describe the Logic approach.
if anyone finds any problems here or mistakes please let us know…geoff
This workflow is for a Motu 828 audio interface,
(other multiple input and output interfaces maybe similar…) using Logic Pro.
Logic is a very complex app but I will describe here a quick intro
to mixing your audio, by doing a simple test with software instrument tracks.
The workflow is very similar for audio tracks in Logic, instead of creating the 6 software instrument tracks ,
create 6 audio tracks and drop your sounds onto them.
You will need:
Motu 828 or similar, 5 speakers and a subwoofer and a 5.1 amplifier, Logic Pro.
Attach your speakers to 5.1 amp and connect to Motu, connect Motu to Mac via firewire…(others maybe USB)
turn it all on.
Openi audio midi setup In Mac from Finder >Applications > Utilities >audio midi setup > Audio devices
RMB in left column over Motu 828, in input tab select "use this device for sound input" same for output…
change Format to 48000hz, I use analogue at the moment.
configure speakers for surround while you are there, button bottom right corner of window…
(optional) changeLogic to 64 bit in Finder >Applications:
click Logic app icon once and cmd+i - uncheck open in 32 bit.
Start a new empty Logic project with 6 software instrument tracks and Output Surround.
File> project Settings > Audio Sample Rate 48.000khz , Surround Format 5.1
check Logic prefs > audio are output and input to Motu.
Check Logic prefs general>caps lock keys is enabled
Check Mac System prefs > Sound are also seeing Motu as out and in.
Notice the Channel strips on the bottom left of the screen, the left one is the track input and the right is overall output.
To test the system do the, although you can create audio tracks and drop your files onto them if you want when you have got a working system.
Select track 1, and in input channel strip click Setting and choose an instrument setting e.g. World>Caribbean>drums
(The right hand channel strip is output and we don't need to add any Setting to that just yet)
enable record in selected track 1 - ctrl+R or click little 'R' button in track
put caps lock on, on Mac keyboard (MKB)
notice floating window representing a MKB
type on your Mac keyboard ASDGFGHJDGHJ hear the music?
turn off the caps lock keyboard by turning off caps lock key on MKB
This is a cheap and easy way to make any amount of sounds without buying a midi keyboard,
and works with thousands of preinstalled instruments.
Record some music:
Go to the start of the timeline, start recording by either hitting R (if caps lock off) on MKB or
pressing the eighth button in the row to the left of the centre bottom panel, (the last button in the transport controls section)
Play some sounds on your MKB (with aps lock on)
Hit the space bar to stop recording.
Select each track and add a new instrument by holding down the Settings button and choosing from the many options.
Record something on each track/instrument.
In the track input channel strip double click the surround icon - a circle with a dot. This makes a bigger surround control for the track.
The placement of the sound can be controlled from here as can the amount of LFE (subWoof) for each track.
If you have your speakers setup correctly you will be able to move the sound all around the room and to the centre.
Leave the LFE in the middle for most instruments usually…the Bass maybe more…:-)
Double click each surround icon in each track…they are all independent.
save…not auto save here
Click the bounce icon top right Logic window
Save as destination and name 5.1mySong.
check PCM uncheck all others, select PCM Destination line to see options to the right
Below left check start and end times, offline, normalise = overload protection only
To right File format etc.: AIFF, 24bit ,48khz ,interleaved ,dithering none, surround bounce,
click Bounce button at bottom of this window.
Find the file and drag it into iTunes
In FCPXproject with properties surround sound- audio pan mode none:
find the file…
drag it to the timeline…
play the timeline and notice the 6 tracks in audio meters
export as H.264…or your favourite.
play the movie check audio coming out of all speakers
Done…take a break
