Warped Regions
Regions that have been warped either manually
or automatically by tempo change, quantiza-
tion, or pitch shifting display a Warp indicator
in the upper right-hand corner of the region.
This indicator is visible in any track view. Since
unwarped regions can reside on Elastic Audio-
enabled tracks, regions on Elastic Audio-enabled
tracks do not necessarily display the Warp indi-
cator. The Warp indicator only indicates that
Elastic Audio processing has been applied to a
region.
Displaying the Warp Indicator
The Warp indicator for Elastic Audio regions can
displayed or hidden.
To toggle the display of the Warp indicator in
Elastic Audio regions:
„ Select or deselect View > Region > Processing
State .
Out of Range Processing
Pro Tools lets you apply extreme amounts of
Elastic Audio processing. However, at such ex-
tremes, it is possible to go out of the selected
Elastic Audio plug-in’s processing range. When
this happens, it is possible that not every sample
will be processed correctly and you may encoun-
ter audio drop outs.
The valid range for Elastic Audio TCE processing
is 1/4x to 4x for all Elastic Audio plug-ins except
X-Form, which supports 1/8x to 8x. TCE less
than or greater than these ranges is effectively
“out of range.”
When out of range processing occurs, the sec-
tion of the audio region that is out of range
turns red. You can still apply Elastic Audio pro-
cessing, but you are warned by the color change
that the TCE factor is out of the normal range of
Elastic Audio processing.

The TCE Factor in the Elastic Properties
window supports extreme ranges from
1–9999%. However anything outside of
25–400% will be “out-of-range” and will
be displayed in red.
