Add fades to audio files in Logic Pro for Mac
You can use the Audio File Editor to destructively add a fade-in or fade-out to an entire audio file, or on a selected area of the file. Your changes permanently alter the original file.
Fade-In: Volume is set to 0 at the start point of the selected area, and the fade-in occurs over the length of the selection.
Fade-Out: Volume is set to 0 at the end point of the selected area, and the fade-out occurs over the length of the selection.
The fade-in or fade-out time is determined by the selected area within the audio file.
Note: You cannot use the Fade-In and Fade-Out functions on Apple Loops, surround files, or regions on tracks where Flex Pitch is turned on. If possible, you can bounce the region in place and add fades to the resulting audio file. Alternatively, you can use the Fade tool or the Fade-In and Fade-Out parameters in the Region inspector to create more flexible and non-destructive fades.
Tip: The Fade tool in the main window offers a flexible, non-destructive fade option. For more information, see Create fades on audio regions in Logic Pro.
