Retune Speed
Auto-Tune Evo 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 infamous “Cher
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 Evo allows real-time adjustment of
the depth of any natural vibrato present in the
input.
Auto-Tune Evo 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 Evo’s Vibrato settings, you can even
remove a performer’s own vibrato and replace
it with Auto-Tune Evo’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 Evo’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 Evo from trying to correct the seriously
flat tail of the last note to those pitches. See
Chapter 3 for more details.)
