Reset
Click the Reset button to reset event analysis
data for the region to match the original file.
The Event Sensitivity property is reset to 100%.
Input Gain
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 774).
If you encounter clipping when processing Elas-
tic Audio, use the Input Gain property to atten-
uate the gain of the audio signal before it is pro-
cessed.
Pitch Shift (Polyphonic, Rhythmic, and X-Form
Only)
The Pitch Shift property lets you pitch shift
whole regions on Elastic Audio-enabled tracks
using the Polyphonic, 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.
3
Open the Elastic Properties window for the re-
gion.
4
Adjust the
Pitch Shift
settings up (“+”) or down
(“–”) by an amount in semitones and cents.
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.
