Scale
Detune
The Detune
parameter
allows you
to change
the pitch standard of Auto-Tune Evo from
the default A = 440Hz. The value is set in
cents (100 cents = 1 semitone). The range
of adjustment is from -100 to +100 cents.
For convenience, the detune amount is also
displayed in Hertz relative to A440.
The Detune function can be used to tune
a vocal performance to some irreparably
out-of-tune instrument (a piano or organ, for
example), or to allow correction to other than
the conventional 440Hz standard.
A TIP: If you have a tone that you
want to use as the pitch standard,
select that tone and play it in a loop.
Adjust Scale Detune until the Change meter
reads zero. (You may be required to use the Edit
Scale Display to remove adjacent notes so that
Auto-Tune Evo doesn’t tune to the wrong note.)
The default Scale Detune setting is 0 cents.
Double-clicking or Command (Mac)/Control
(PC) clicking the Scale Detune knob will reset it
to that value.
Transpose
In addition to any pitch
correction applied by
either Automatic or
Graphical Mode, the
Transpose control lets
you shift the overall pitch of your performance
over a two octave range (+/- one octave),
selectable in precise semitone increments.
In Automatic Mode, this transposition is
accomplished in real time.
In Graphical Mode, this function does not
affect the Pitch Edit Display. It provides overall
transposition on top of any pitch shifting
accomplished with the graphical editing tools.
As noted above, although you can also
accomplish overall transposition in Graphical
Mode by selecting all the correction objects
in your track and manually moving them up
or down, in most cases, using the Transpose
function will provide superior results.
NOTE: If you are transposing
more than a semitone or two
and your intent is to preserve
the performer’s vocal character, be sure to
engage the Formant Correction function
described below. Transposing large intervals
(especially transposing higher) without formant
correction will result in the “munchkinization”
effect familiar from tape speed changing and
early digital sampling. (Of course, if singing
chipmunks are what you’re going for, leave
Formant Correction off.)
The default Transpose setting is 0 semitones
(i.e., no transposition). Double-clicking or
Command (Mac)/Control (PC) clicking the
Transpose knob will reset it to that value.
Throat Length
As mentioned above,
the shape of a singer’s
throat is a prime
contributor to their
vocal character. Auto-
Tune Evo lets you modify the vocal quality of a
performance by actually varying the geometry
of a physical model of the human vocal tract
and processing the original performance
through that model.
The Throat Length control lets you modify the
length of the modeled throat. The range of
the control is .50 to 1.80. Values above 1.00
represent a lengthening of the throat while
values below 1.00 represent a shortening of the
throat.
The actual values represent the percentage
change in the throat length. For example, a
value of 1.20 represents a 20% increase in
throat length, while a value of 0.70 represents a
30% decrease in throat length.
NOTE: This control is only active when
Formant Correction is engaged.
When Formant Correction is not
engaged, this control is disabled (grayed out).
Since Formant Correction is not available in the
TDM versions of Auto-Tune Evo, Throat Length
is also not available in the TDM versions. If
