Reset Button
Click the Reset button in the Elastic Properties
window to reset event analysis data for the re-
gion to match the original file. The Event Sensi-
tivity property is reset to 100%.
Input Gain Property
It is possible to encounter clipping when time
compressing audio. Real-Time Elastic Audio
plug-ins provide a Clip indicator to let you know
when clipping has occurred and the Elastic Au-
dio plug-in button turns red. Rendered Elastic
Audio regions display a Clip indicator on the re-
gion when clipping has occurred (see “Region
Clip Indicator” on page 866).
If you encounter clipping when processing Elas-
tic Audio, use the Input Gain property in the
Elastic Properties window to attenuate the gain
of the audio signal before it is processed.
Pitch Shift Property(Polyphonic,
Rhythmic, and X-Form Only)
The Pitch Shift property in the Elastic Properties
window lets you pitch shift whole regions on
Elastic Audio-enabled tracks using the Poly-
phonic, Rhythmic, and X-Form plug-ins. You
apply real-time or rendered pitch shifting in
semitones and cents by +/– 2 octaves.
Elastic Audio Region-Based
Pitch Shifting
(Polyphonic, Rhythmic, and X-Form Only)
In addition to Pro Tools Elastic Audio time com-
pression and expansion capabilities, you can
also change the pitch of whole audio regions in
semitones and cents in the range of +/– 2 oc-
taves.
To pitch shift a region:
1 Make sure the region, or regions, you want to
pitch shift are on Elastic Audio-enabled tracks
(using the Polyphonic, Rhythmic, or X-Form al-
gorithm).
2 With the Grabber or Selector tool, select the
audio region you want to pitch shift. Only re-
gions that are completely selected will be af-
fected.
For REX files, Pro Tools converts the slices
as Events with 100% confidence. Conse-
quently, setting the Event Sensitivity from
99% to 1% does not filter out any events
based on slices. However, if you set the
Event Sensitivity to 0%, all markers are
filtered out regardless.
When you change the Event Sensitivity
property, Pro Tools writes temporary fil-
tered Elastic Audio analysis files (.aan) to
the session’s Rendered Files folder. Any
unused temporary filtered analysis files are
purged when you close the session.
Elastic Audio pitch transposition is not sup-
ported with the Monophonic algorithm.
However, if you switch to the Monophonic
plug-in after pitch shifting with another
plug-in, the pitch metadata for the region is
maintained.
Elastic Audio pitch transposition cannot be
applied to looped regions or region groups.
