20—Region Editing Operations
Once you've defined the desired region, the location of the TO point determines
whether the region's audio will be stretched out or shrunk. If the TO point is:
•
•
Why You'd Want to Use Region COMP/EXP.
You can use COMP/EXP. to make audio fit a groove in a dance track. You can also use it
to make a region meet the time constraints of a TV or radio commercial or a soundtrack.
You can stretch a region to fill a blank space in the playlist by placing TO at the
beginning of the next audio. Likewise, if a region's too large to fit in an available gap,
place TO where the region overlaps the audio following it to shrink it to the right size.
Edit Points
•
•
The length of time between the IN and OUT points must be greater than 0.5 seconds.
•
You can compress the region's length to as little as 75% or expand by as much as 125%.
Be aware that the more extreme the amount of compression or expansion, the more the
region's audio quality may degrade.
TYPE
The VS-2400CD offers three different time compression/expansion algorithms. Select
the one that most closely describes the region's audio:
•
Pitch
When Pitch is set to:
•
•
Amp
The time compression/expansion process can change a region's level, and if its level
becomes too high, distortion results. The Amp parameter lets you set the region's post-
processing loudness. We recommend trying a setting of 60% to start. If the processed
region is too quiet, perform an Undo and try again with a higher percentage. You can
set this parameter to the following level percentages: 50, 60, 70, 80, 90, 100.

before the OUT point—the region's audio is made shorter in duration.
after the OUT point—the region is made longer in duration.
Compression
IN
IN—sets the beginning of the region to be stretched or shrunk.
OUT—sets the end of the region to be stretched or shrunk.
TO—sets the amount of time compression or expansion to be applied, according to
its position before (compression) or after (expansion) the OUT point.
A: Vocal, Narration
Variable—the region's pitch is raised or lowered by the same amount that its length
is compressed or expanded, respectively.
Fixed—the region's pitch stays the same regardless of the change to its length.
