None Disables linking between the fade-out and
fade-in curves, and lets you freely adjust them
separately, including start and end points. This
option also allows you to create custom cross-
fade shapes.
When Link is set to Equal Power or Equal Gain,
you can edit only the fade-in portion of the
curve, by pressing Alt (Windows) or Option
(Mac) while dragging. To edit only the fade-out
portion of the curve, press Control (Windows)
or Command (Mac) while dragging.
Slope Settings
(Fade-In or Fade-Out Only)
The Slope settings affect the slope of the fade-in
or fade-out. Select either equal power or equal
gain. For more information on equal power and
equal gain fades, see “Link Settings” on
page 469.
Use Dither
The Use Dither option turns on a preset, noise-
shaped dither function that improves audio per-
formance when fading in or fading out of si-
lence, and crossfading between low amplitude
regions. Dithering is usually not necessary when
applying fades to regions with audio at high am-
plitudes. You can disable Dither while editing
fades in the Fades dialog to speed up previews
and fade recalculation, then re-enable Dither to
create the final fade or crossfade.
Fade-In Shape Settings
The In Shape setting lets you define the shape of
the fade-in to a region for a fade, or to region 2
for a crossfade.
Standard Selects a single continuous fade curve.
This creates a general-purpose fade that can be
edited by dragging the curve itself.
S-Curve Selects an S-shaped curve, which inverts
its beginning and end characteristics. This
makes it possible to fade in faster at the start of
the curve, and slower at the end. S-shaped
curves are useful with material that is difficult to
fade effectively. S-curves can be edited by drag-
ging the curve in the curve editor.
