gion has been warped to remain two-bars long
at the slower tempo, it displays the Region Warp
indicator in the upper right-hand corner of the
region.
Figure 41. Tempo conformed audio, linear tempo
change
For tempo curves, such as an accelerando or ri-
tardando, Tempo Event Warp markers are auto-
matically created corresponding to each tempo
event, and the region conforms accordingly.
Figure 42 below shows a region in Warp view.
Notice how the audio conforms to the tempo
curve.

Tempo Event-generated Warp markers cannot
be edited. They only show where the audio has
been warped in order to conform to tempo
changes.
If you change the track timebase from ticks
to samples, any Tempo Event–generated
Warp markers convert to regular, editable
Warp markers.
Conform to Tempo
Pro Tools lets you conform regions on Elastic
Audio-enabled tracks (both sample- and tick-
based) to the session tempo. If necessary, the
Conform to Tempo command analyzes the se-
lected regions to determine its tempo and dura-
tion (in bars and beats), and then applies Elastic
Audio processing to conform the region to
match the session tempo.
To conform a region to the session tempo:
Select the region you want to conform to the
1
session tempo.
Do one of the following:
2
• Choose Region > Conform to Tempo.
– or –
• Right-click the region you wan to conform
to tempo and select Conform to Tempo.
Pro Tools analyzes the region's entire file for
Elastic Audio events and tempo. If a tempo is de-
tected, and a duration in bars and beats is deter-
mined, the region conforms automatically to
the session tempo. If a tempo and duration is
not detected (such as with a region that is a sin-
gle drum hit or with a long region with no clear
tempo), the region is not conformed to the ses-
sion tempo.
You can also use telescoping warp in Warp
view to manually conform a long region to
the session tempo. See "Telescoping Warp"
on page 780.
Conform to Tempo can only be applied to
regions and cannot be applied to region
groups. To conform region groups to the
tempo you must first ungroup the region
group, then apply Conform to Tempo to the
underlying regions, and then regroup those
regions.
