In this episode of minute GarageBand we're going to show you how to split a single stereo
track into two separate tracks.
If you've used two mics, or even 2 DIs to record a pair of vocals, guitars, or say a
kick and snare on to a single stereo track, you may find that you want more control over
the mixing of them, for instance being able to use different EQ settings for one while
not affecting the other with the same settings.
In this example we have two lead guitars, each recorded on a single channel of a stereo
track, one left, and one right.
While GarageBand itself doesn't offer a method for spitting up the channels of a single track,
it's not difficult, and we can use iTunes to do the job.
Open iTunes, and then open its preferences. Click Import Settings, choose AIFF encoder
from the Import Using popUp menu, and then Custom from the Settings popUp menu.
Make sure the sample rate is 44.1k, the sample size is 16-bit, and set the channels to mono,
then close the prefs and return to GarageBand.
Set the track's pan fully left, and export using Song to iTunes via the share menu.
Then set the pan fully right and again export to iTunes.
The next step is to let iTunes convert our one sided stereo files into mono files so
that sound will come from both speakers.
Control-click one of the files, and if you've set iTunes preferences as we did, pick "Create
AIFF version" from the popUp menu.
Now repeat this process for the other file.
We set up a smart playlist so we could easily find our newly created files, and when we
open that we find that along with our original exports we have two new mono copies of those
files which we can drag and drop back into GarageBand
Now each guitar is on its own track ready to paned, EQed, and effected as desired.
That's all we have for this episode
