30 Chapter 4 Audio Export and Import
Pan tracks
If this box is checked, Logic adds information to the OMF file which sets the panning of
the exported tracks as they appear in Logic itself (Stereo tracks in Universal Track Mode
are exported as two mono tracks. Assuming this option is checked, the left mono track
is panned to the left and the right one, to the right).
Warning: This does not work with OMF Tool or DigiTranslator. Don’t check this box if
you are using OMF Tool to convert the OMF file into a ProTools session, as it is
unsupported by OMF Tool.
Convert 24 bit files to 16 bit
This setting converts all 24 bit files to 16 bit using the Dithering type described below.
This might be necessary when using older versions of ProTools.
Dithering Type
When exporting 24 bit recordings into 16 bit files and the audio files are included in the
OMF file, dithering is recommended.
Executing Export
After pressing the OK button, a file dialog allows you to specify the destination folder
of the OMF file to be generated. Choose a location and you’re done. If you have
checked the Include Audio option, Logic will display a progress bar for each exported
audio file.
OMF Import
The File > Import menu option will open a file selector, which allows you to choose OMF
files.
After selecting a file, a further dialog allows you to choose the location for the audio
data extracted from the OMF file.
Following confirmation of this dialog, the OMF file is imported into the currently open
song—new audio tracks are generated for every track contained in the OMF file, and
the audio parts are placed appropriately on these tracks.
AAF Export
To export the current song as an AAF file, choose File > Export > Export Song as AAF file.
This will export all used audio files and Regions with reference to tracks and position,
volume automation included.
AAF Import
The File > Import menu option will open a file selector, which allows you to choose AAF
files.
