Quantizing Audio Regions
Pro Tools lets you quantize audio region start
times (or sync points) using the Quantize opera-
tion. Audio region start times (or sync points)
are quantized to the nearest quantize grid value.
To quantize audio regions:
1
Select the audio regions you want to quantize.
2
Choose Events > Event Operations > Quantize .
3
In the Quantize window, select
Audio Regions
from the What to Quantize pop-up menu.
4
Set the Quantize Grid and Options settings.
5
Click
Apply
.
The region start times (or sync points if present)
are quantized according to the quantize settings.
Quantizing Mixed Selections
You can apply Quantize to both MIDI notes and
audio regions, or both MIDI notes and Elastic
Audio events at the same time. However, you
cannot apply Quantize to both audio regions
(non-Elastic Audio) and Elastic Audio events at
the same time.
Restore Performance
The
Restore Performance
command reverts all se-
lected MIDI notes to their original state (when
first recorded or manually inserted), even after
the session has been saved, or the Undo queue
has been cleared.
Restore Performance
can also
be applied to quantized Elastic Audio Events or
quantized audio regions.
The following MIDI note, Elastic Audio Event,
and audio region attributes can be restored:
Timing (Quantization)
Restores the original start
times of the selected notes, audio regions, and
Elastic Audio Events. For MIDI only, this
changes the durations of selected notes if the
Du-
ration
option is not enabled.
Quantizing region groups only adjust the
location of the region group start (or sync
point). To quantize the underlying sliced
regions in a region group, you must first
ungroup, then quantize, and then regroup.
For more information on region groups, see
“Region Groups” on page 743.
