3. Set the Retune Speed to 20 and play back the sound. Experiment with
other Retune Speeds to hear their effects.
Vibratos and other pitch gestures typically occur with related loudness
gestures. Specifically, with vibratos, some vocalists produce mostly pitch
variations and little loudness variations while others produce small pitch
variations and a lot of loudness variations (the latter is often called
tremolo). Nonetheless, almost all voices seem to produce a combination of
both pitch and related loudness variations. Therefore, trying to take an
existing vibrato and change it (say speed it up) often sounds unnatural
because the new pitch variation does not correspond to the original (and
still present) loudness variation.
These considerations are also important when correcting pitch. It’s rarely
effective to draw in a new pitch gesture at the desired pitch, even though
that gesture may have worked well in another performance.
As this tutorial has demonstrated, the following two techniques are the
most commonly successful approaches to Graphical Mode pitch correction:
• The first technique uses the Make Curve button to create a curve of the
existing pitch, allowing you to drag that curve up or down, or stretch it
by dragging one end vertically. The Retune slider can then be set very
fast (0 to 5). This will force a precise re-tuning, but will sound ex-
tremely natural since the target pitch curve will precisely synchronize
with the original loudness gestures of the voice.
• The second technique is to draw a flat line segment across the duration
of a tone at the desired pitch and then set the Retune Speed in the
range of 20 to 40. This has the effect of gently moving the input pitch
towards the desired pitch. The slower values of 20 to 40 will let
through a vibrato but still draw the overall pitch closer to being in
tune. The average pitch will eventually settle to the given line and the
pitch gestures will occur both sharper and flatter relative to that line.
The settling time is about twice the Retune Speed setting (in millisec-
onds). 20 to 40 will let through about one-half of a typical vibrato.
Slower settings will let through more vibrato but will cause the new
pitch to be reached more slowly.
