Chapter 38: Elastic Audio 791
To transpose the pitch of an audio region in the
Transpose window:
1 Make sure the region, or regions, you want to
Transpose 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 transpose. Only re-
gions that are completely selected will be af-
fected.
3 Choose Event > Event Operations > Transpose.
4 Do one of the following:
• Adjust the Transpose By settings by an
amount in semitones and cents.
– or –
• Adjust the Transpose From and To settings
by an amount in Semitones and Cents.
5 Click Apply.
Varispeed and Pitch Shifting
When using the Varispeed algorithm, pitch
transposition and time compression/expansion
are always linked. If you apply pitch transposi-
tion to an audio region using the Polyphonic or
Rhythmic algorithms, that transposition data is
stored in the metadata for the region. Conse-
quently, if you then switch to Varispeed, change
the TCE factor, and then switch back to the orig-
inal Elastic Audio algorithm, the region will re-
vert to the original amount of pitch shifting
while maintaining the amount of time compres-
sion/expansion applied by the Varispeed algo-
rithm.
Removing Region Pitch Shifting
If you have applied any pitch shifting to a re-
gion, you can remove pitch shifting and revert
the region to its original pitch. This can be use-
ful if you are not satisfied with the results and
want to revert to the pre–pitch shifted region.
