Chapter 21: Fades and Crossfades 471
Preset Curves Seven commonly used preset
curves are provided for fast creation. These can
be edited by dragging the end points of the
curve in the curve editor portion of this dialog.
The seven presets are as follows:
◆ Preset Curve 1 fades in at full volume immedi-
ately at the beginning of the fade and keeps it
there throughout the fade.
◆ Preset Curve 2 fades in quickly in the begin-
ning, reaching full amplitude fairly early in the
fade.
◆
Preset Curve 3 fades in moderately fast.
◆
Preset Curve 4 fades in with a linear fade
curve. This is the default curve.
◆
Preset Curve 5 fades in slowly at the begin-
ning of the fade.
◆
Preset Curve 6 fades in even more slowly than
the previous curve.
◆ Preset Curve 7 silences any audio until the
end of the fade.
Typical Curve Combinations
Following are the available combinations of
fade-out and fade-in curves.
Linear Crossfade This is a good general purpose
crossfade with a smooth, even transition be-
tween region 1 and region 2.
Equal Power Crossfade This is a good general
purpose crossfade useful in cases where a linear
crossfade seems to create a noticeable drop in
volume across the splice point.
Overlap Fade This combination of curves keeps
both regions at full amplitude throughout the
crossfade: region 2 “jumps in” at the beginning
and region 1 “jumps out” at the end.
