Retune Speed
Auto-Tune 7 also gives you control over how
rapidly, in time, the pitch adjustment is made
toward the scale tone. This is set with the
Retune Speed control (see Chapter 3 for more
details).
Fast Speed settings are appropriate for short
duration notes and for mechanical instruments,
like oboe or clarinet, whose pitch typically
changes almost instantly. A fast enough setting
will also minimize or completely remove a
vibrato, as well as produce the iconic Auto-Tune
Vocal Effect.
Slow Speed settings, on the other hand, are
appropriate for longer notes where you want
expressive pitch gestures (like vibrato) to
come through at the output and for vocal and
instrumental styles that are typified by gradual
slides (portamento) between pitches. An
appropriately selected slow setting can leave
expressive gestures intact while moving the
average pitch to the correct tonal center.
Vibrato
Auto-Tune 7 allows real-time adjustment of the
depth of any natural vibrato present in the input.
Auto-Tune 7 can also add a vibrato to an input
that does not naturally exhibit one. You can
program the vibrato rate along with individual
vibrato depths for pitch, amplitude (loudness)
and formant (resonant frequencies). You can
also specify delayed vibrato with independently
programmable onset delay and onset rate.
By combining a fast Retune Speed setting with
Auto-Tune 7’s Vibrato settings, you can even
remove a performer’s own vibrato and replace
it with Auto-Tune 7’s programmed vibrato, all in
real time. Also, unusual combinations of Vibrato
Waveform, Rate and Depth settings can be
used for some interesting special effects
An Example of Automatic Mode Correction
As an example, consider this before-and-
after graphic representation of the pitch of a
vocal phrase that contains both vibrato and
expressive gestures.
In the original performance, we can see that
although the final note should be centered
around D, the vocalist allowed the tail of the
note to fall nearly three semitones flat. The
“after” plot is the result of passing this phrase
through Auto-Tune 7’s Automatic Mode
programmed to a D Major Scale (with C# and B
set to ”Remove”) and a Retune Speed setting
of 25. That Retune Speed causes the pitch
center to be moved to D, while still retaining
the vibrato and expressive gestures. (Setting
C# and B to ”Remove” is necessary to keep
Auto-Tune 7 from trying to correct the seriously
flat tail of the last note to those pitches. See
Chapter 3 for more details.)
