498 Chapter 21 Editing Audio in the Sample Editor
 Choose Functions > Fade Out (default key command: Control-O) to fade passages
out automatically.
∏ Tip: If you use the Silence function (see “Silencing an Audio File Section” on page 498)
to remove unwanted background noise from silent passages, small jumps in volume
can sometimes appear at the silence start and end points. In this situation, zoom in,
and select a small area surrounding (just before and after) the start point of the signal,
then use the fade-in function.
To adjust the fade curves:
1 Open the Functions Settings window by choosing Function > Settings.
2 Edit the Curve value to change the shape of the fade-in or fade-out curve.
3 Turn on the S Curve checkbox if you want to create s-shaped curves.
These settings are automatically stored in the Preferences when Logic Pro is closed, and
apply to all projects.
∏ Tip: Common fades (such as a fade-out at the end of a track) can also be achieved with
Mixer, automation, or Hyper Draw functions. The Arrange window Crossfade tool offers
a further, flexible, non-destructive fade option (see “Creating Crossfades and Fades on
Audio Regions” on page 342).
Silencing an Audio File Section
You can use the Silence command to set all amplitude values to zero, rather than
removing (with Cut or Delete) all data from the selected area of an audio file. This
function is generally used to silence unwanted background noise in quiet passages.
To silence the selected area of an audio file:
m Choose Functions > Silence (or use the corresponding key command, default: Control-
Backspace).
