Apple Logic Express 9 - Manual (Page 563)

Tip: If you use the Silence function (see Silencing an Audio File Selection in the Sample
Editor ) to remove unwanted background noise from silent passages, small jumps in
volume can sometimes appear at the silence start and end points. If this happens, zoom
in and select a small area surrounding—just before and after—the start point of the
signal, and then use the fade-in function.
To adjust the fade curves
1 Open the Function Settings window by choosing Functions > Settings.
2 Edit the Curve value to change the shape of the fade-in or fade-out curve.
