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 eect
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 8.
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:
7. Use the I-Beam Tool to drag a selection in
the Pitch or Envelope Graph as shown:
