7. Click the Make Curve button. Auto-Tune 8
will compute a new blue curve object from
the existing pitch data as well as a green
output curve that reflects the default
Curve Retune Speed. (The new curves may
be dicult to see at first because they
may exactly overlay the red curve.) Click
the I-Beam Tool on the background of the
Pitch Graph to cancel the area selection.
8. Select the Arrow Tool and click precisely
on the left end of the curve to select only
the left anchor point (you’ll know you’re
over the anchor point when the cursor
changes to the up-and-down arrow
cursor). Drag this straight up, stretching
the curve so it is centered around the D3
graph line.
9. Drag the Arrow tool across all of the visible
curves to select them. Then move the
Arrow Tool over the body of a correction
curve so that the cursor changes to the
horizontal bar. Click and drag the curves
straight down so they centered on the C3
graph line. The Pitch Graph should now
appear as follows:
10. Set the Retune Speed to  and play back
the sound. Note that the errant note is
now in tune.
To continue, here is an alternative approach to
the same pitch problem using the Line Tool.
1. Click “Select All” and then click “Cut” to
delete the curves you created in the steps
above.
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 eect on the green
correction curve and to hear their eects.
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 eective to draw in
a new pitch gesture at the desired pitch, even
though that gesture may have worked well in
another performance.
