Audio processing and functions
Formant Mode
If you are processing vocal material, you should activate
this option in order to preserve the vocal characteristics of
the pitch-shifted audio and to avoid a a “chipmunk voice”
effect.
Time Correction
When this is activated, the pitch shift process will not af-
fect the length of the audio. When this is deactivated, rais-
ing the pitch will shorten the audio section and vice versa,
much like changing the playback speed on a tape recorder.
Using envelope based Pitch Shift
When the “Envelope” tab is selected, you can specify an
envelope curve on which the pitch shift should be based.
This allows you to create pitch bend effects, pitch-shift
different sections of the audio by different amounts, etc.
Envelope display
Shows the shape of the envelope curve over the wave-
form image of the audio selected for processing. Envelope
curve points above the center line indicate positive pitch
shift, while curve points below the center line indicate
negative pitch shift. Initially, the envelope curve will be a
horizontal, centered line, indicating zero pitch shift.
You can click on the curve to add points, and click and
drag existing points to change the shape. To remove a
point from the curve, drag it outside the display.
Curve Kind
These buttons determine whether the envelope curve
should consist of spline curve segments (left button),
damped spline segments (middle button) or linear seg-
ments (right button).
Spline curve segment envelope.
The same envelope with damped spline segments selected.
The same envelope with linear segments selected.
Range
This parameter determines the vertical pitch range of the
envelope. If set to “4”, moving a curve point to the top of
the display corresponds to pitch shifting by + 4 semi-
tones. The maximum range is +/- 16 semitones.
