Creating a low pitched voice
Interesting animated characters, monster or alien voices
are often created with large down-shifts. Follow the steps
below to down-shift and adjust the quality.
1. Enter the Browser Tab by pressing the Browser Button.
2. Use Edit 1 and 2 to configure the Source Filter to
"Speaking", and the Application Filter to "Pitch & Time".
3. Using the Select/Scroll Wheel or the Arrows to select the
preset "Large Down Shift"
4. When you've selected the preset, press "Ok" to load.
5. Enter the Pitch | Pitch Shift Tab by pressing the Pitch
Button and using the Arrow Buttons.
6. Set the Coarse Shift Parameter to the desired downshift
amount
7. Manipulate the UV Shift Amount and Formant Correct
Amount to modify the quality of the down-shift.
The Downshift Quality Parameter is best used for
smoothing out the 'breaks" in a voice introduced
when its down-shifted beyond an octave.
Re-phrasing the Timing of a
Performance
VoicePro's Time Block uses TC-Helicon's FlexTime TM
algorithm to stretch and speed up a voice performance.
The buffer for the Time effects is 5 seconds. The main
application for the Time block is dynamic control over the
phrasing of a voice by slowing down and speeding up
words or phrases. Additionally, it is possible to reduce or
increase the length of a 30 second voice clip by +/-17%
Real-time control over timing
1. Enter the Browser Tab by pressing the Browser Button.
2. Use Edit 1 and 2 to configure the Source Filter to
"Speaking", and the Application Filter to "Pitch & Time".
3. Using the Select/Scroll Wheel or the Arrows to select the
preset "Pitch & Time Freestyle"
4. When you've selected the preset, press "Ok" to load.
5. Enter the Time | Rate Freestyle Tab by pressing the
Time Button and using the Arrow Buttons.
The Time block is typically configured to start at
the beginning of the buffer. This means the first
operation has to be slowing down the voice.
However, it is possible with the Reset Position
Parameter to set the buffer starting point to be
"Middle" This will allow the audio rate to be
increased or decreased.
