Chapter 24 Managing Audio Files 567
Optimizing Audio Files
Beyond deleting unused audio files, Logic Express also allows you to delete unused
portions of audio files. This usually frees up a lot of wasted space on the hard disk.
To delete sections of audio files that are no longer used in the project:
1 Select the audio files that you want to optimize in the Audio Bin.
The Edit > Select Used menu should be your first port of call. Optimize Files can be
used on any number of audio files.
2 Choose Audio File > Optimize Files (or use the corresponding key command,
default: Control-O) in the Audio Bin.
The following happens during the Optimize Files function:
 Logic Express determines which (file) segments are not contained in any of the
regions used in the Arrange area.
 These segments are deleted, and the remaining portions of the audio file (those used
by regions) are retained. These file segments are aligned side-by-side in the file.
Note: For safety reasons, the Optimize Files function uses a pre and post roll area of
one second of audio data before and after each (used) region.
 The regions in the Audio Bin are redefined.
 The project is automatically saved.
Saving Regions as Individual Audio Files
You can create one (or more) independent audio files from selected regions in the
Audio Bin and Arrange area.
To convert selected regions into independent audio files:
1 Do one of the following:
 Choose Audio File > Save Region(s) As in the Audio Bin.
 Choose Audio > Convert Regions to New Audio Files in the Arrange area (or use the
corresponding key command, default: Option-Command-F).
 Choose File > Export Region as Audio File in the main menu bar (or use the
corresponding key command).
2 Choose the desired settings in the ensuing dialog boxes.
3 Browse to, and choose the target folder for the new audio files. You may also create a
new folder, by clicking the New Folder button.
Warning: As this process physically deletes data from the storage medium, it cannot
be undone.
