2. Make sure Snap To Note is engaged and
use the Line Tool to draw a horizontal line at
C3 as shown below:
3. Set the Retune Speed to 20 and play back
the sound. Experiment with other Retune
Speeds to see their effect on the green
correction curve and to hear their effects.
Some notes:
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 provide 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 Speed 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.
Tutorial 9: Import Auto Function
The Import Auto function allows you to display
and edit the pitch corrections that would result
from specific Automatic Mode settings.
1. Setup to process the file “Crowd All”
through Auto-Tune 7.
2. Set the Key and Scale to C Major. Select
Automatic Mode and set the Retune Speed
to the default of 20.
3. Select Graphical Mode.
4. Press the Track Pitch button.
5. Play the “Crowd All” file.
6. Select the Magnifying Glass Tool and drag
out a box on the Pitch Graph that encloses
the red curve for the words “crowd all
rushed.” You will see something like the
following:
