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 8’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 general shape of the expressive
gestures. (Setting C# and B to ”Remove” is
necessary to keep Auto-Tune 8 from trying to
correct the seriously flat tail of the last note to
those pitches. See Chapter 3 for more details.)
Flex-Tune
New in Auto-Tune 8 is the Correction Style
control. Other real-time pitch correction
methods, including previous versions of Auto-
Tune, are always pulling every note towards
a scale note, in the process distorting any
of the singer’s expressive vocal gestures. In
contrast, Flex-Tune only provides correction
when the vocalist approaches a scale note. At
all other times, they are free to sing with
whatever vocal gestures best express their
emotional connection to their song, secure in
the knowledge that Auto-Tune 8 will pass them
through, exactly as they are sung.
The new Correction Style control lets you
choose how close to the scale pitch the singer
has to be for Auto-Tune 8 to apply correction.
In the Classic position, correction is always
applied. This results in the same style of
correction as previous versions of Auto-Tune.
As you move the control into the Flex-Tune
range, the correction area around the scale
note gets smaller and smaller until, at the
extreme clockwise position, no correction will
be applied at all.
An Example of Flex-Tune Correction
In this example, we first look at the plot of
a vocal line with intricate vocal gestures
processed with the Correction Style control set
to (classic Auto-Tune correction). As you can
see, the scale notes are in tune, but the various
gestures are distorted by also being pulled to
the scale notes.
This second plot shows the result of setting
the Correction Style control to the Flex-Tune
setting of 75. The vocal gestures are now
reproduced exactly as they were sung.
Vibrato
Auto-Tune 8 allows real-time adjustment of
the depth of any natural vibrato present in the
input.
Auto-Tune 8 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 8’s Vibrato settings, you can even
remove a performer’s own vibrato and replace
it with Auto-Tune 8’s programmed vibrato, all in
real time. Also, unusual combinations of Vibrato
Waveform, Rate and Depth settings can be
used for some interesting special eects.
