1. Click the Clear All button to delete the blue
curve created above.
2. Use the Line Tool to draw a horizontal line
as shown below (press the Option/Alt key
to constrain the line to horizontal):
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 extremely 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 milliseconds). 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.
