Fades, crossfades and envelopes
Preview, Apply and Process
The buttons in the bottom row are different depending on
whether you are editing a fade made with the fade handles
or applying a fade using processing:
The Edit Fade dialogs have the following buttons:
The Process Fade dialogs have the following buttons:
Creating crossfades
Overlapping audio material on the same track can be cross-
faded, for smooth transitions or special effects. You create
a crossfade by selecting two consecutive audio events and
selecting the Crossfade command on the Audio menu (or
by using the corresponding key command, by default [X]).
The result depends on whether the two events overlap or
not:
• If the events overlap, a crossfade is created in the over-
lapping area.
The crossfade will be of the default shape – initially a linear, symmetric
crossfade, but you can change this as described below.
• If the events do not overlap but are directly consecutive
(lined up end-to-start, with no gap) it is still possible to
crossfade them – provided that their respective audio
clips overlap! In this case, the two events are resized so
that they overlap, and a crossfade of the default length
and shape is applied.
The default crossfade length and shape are set in the Crossfade dialog
(see “Default buttons” on page 68).
An example:
The events themselves do not overlap, but their clips do. Therefore, the
events can be resized so that they overlap, which is required for a cross-
fade to be created.
When you select the Crossfade function, the two events are resized so that
they overlap, and a default crossfade is created in the overlapping section.
• If the events do not overlap, and cannot be resized
enough to overlap, a crossfade cannot be created.
• Once you have created a crossfade, you can edit it by
selecting one or both crossfaded events, and selecting
“Crossfade” from the Audio menu again (or by double-
clicking in the crossfade zone).
This opens the Crossfade dialog, see below.
Removing crossfades
To remove a crossfade, proceed as follows:
• Select the events and select “Remove Fades” from the
Audio menu.
You can also use the Range Selection tool: drag the Range Selection
tool so that the selection encloses all the fades and crossfades you wish
to remove, and select “Remove Fades” from the Audio menu.
• You can also remove a crossfade by clicking and drag-
ging it outside the track.
