About the crossfade compensation attributes
On the fade-in and fade-out ROM presets submenus, you can find an
item called “Pure shape” along with three “compensation” items:
Note that selecting a compensation attribute for a single fade (not in a
crossfade) will change the shape of the curve, but the actual “compensa-
tion” will only take place when the fade becomes part of a crossfade.
Editing crossfades
The factory default automatic crossfade is linear, using the same shape
and fade lengths for both the fade-in and fade-out. Most of the time, an
unaltered linear or sinus crossfade will produce the desired result. You
can, however, create crossfades with totally independent shapes and
lengths for the fade-in and fade-out curves. The following rules apply:
You can edit the fade-in and fade-out curves in crossfades in exactly the
same way as fades.
To change the crossfade time (the width of the crossfade zone) “symmet-
rically”, press [Shift] and move left and right.
Menu item Description
Pure shape The pure mathematical curve shape is used. This is the default setting
when any fade-in/out ROM preset is selected.
Amplitude
compensation
If this is selected for a fade-in (or fade-out) curve in a crossfade, the
summed fade-in and fade-out amplitudes will be the same all along the
crossfade region.
This option is recommended for short crossfades.
Power
compensation
If this is selected for a fade-in (or fade-out) curve in a crossfade, the energy
(power) of the crossfade will be constant all along the crossfade region.
Crossfading between completely different types of audio material can
sometimes cause harmonics to “cancel each other out” at the crossfade
splice point, causing the volume to drop. Constant power crossfades com-
pensate for this problem. Using either the “Sinus” or “Square-root” fade
ROM presets for a fade-in (or fade-out) will give a constant power cross-
fade without selecting this item.
Medium
compensation
This option provides an intermediary between Amplitude and Power com-
pensation. This is recommended if the other two compensation attributes
won’t provide the desired result.
