Converting regions into independent audio files – Apple Logic Pro 9 User Manual
Page 622
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 option. Optimize Files can be used on
any number of audio files.
2
Choose Audio File > Optimize Files (or use the corresponding key command, default
assignment: Control-O) in the Audio Bin.
The following happens during the Optimize Files function:
• Logic Pro 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.
Warning:
As this process physically deletes data from the storage medium, it cannot
be undone.
Converting Regions into Independent 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 assignment: Option-Command-F).
• Choose File > Export > Region as Audio File in the main menu bar (or use the
corresponding key command).
2
Choose settings in the dialogs that appear.
3
Browse to and choose the target folder for the new audio files. You can also create a new
folder, by clicking the New Folder button.
4
If you’re only saving one region, you can enter a name for the new audio file. The Hide
Extension checkbox hides or shows file extensions (.wav, .aif, and so on) in the Save As
field.
5
Click the Save button.
