Processing Audio
Time Shift lets you change the time and pitch of
selected audio independently or concurrently.
To change the time of a selected audio region:
1
Select AudioSuite > Pitch Shift > Time Shift.
2
Select the Audio Mode appropriate to the type
of material you are processing (Monophonic,
Polyphonic, or Rhythmic).
3
In Monophonic or Polyphonic mode, select
the appropriate Range for the selected material
(Low, Mid, High, or Wide).
4
If compressing the duration of the selection,
attenuate the Gain control as necessary.
5
If using Monophonic mode, adjust the For-
mant Shift control as desired.
6
If using Polyphonic or Rhythmic mode, adjust
the Transient controls as desired.
7
Make sure Pitch Shift is set to 100% (unless
you also want to change the pitch of the selec-
tion).
8
Adjust the Time Shift control to the desired
amount of time change. Time change is mea-
sured in terms of the target duration using the
selected timebase or as a percentage of the orig-
inal.
