Details
Transpose
In addition to any pitch correction applied by
Automatic 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.
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.)
ANOTHER NOTE: Although the
Transpose control is limited to
semitone intervals, you can combine
this control with the Scale Detune control to
pitch shift your track by any arbitrary microtonal
interval over the two-octave range with single-
cent accuracy.
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.
Formant correction
(Native versions only)
Click the Formant button to toggle Auto-Tune
Evo’s formant correction function on and
off. The button will turn blue when formant
correction is active and will be pale gray when
it is inactive.
Engaging Formant Correction prevents the
shifting of a voice’s resonant frequencies
to ensure that its vocal characteristics are
preserved over the pitch shift range. (For
a more complete explanation of formant
correction, refer to the Pitch Shifting and
Formant Correction section in Chapter 2.)
AN IMPORTANT NOTE: Over the very
small intervals usually associated
with basic pitch correction, formant
shifting is essentially inaudible and Auto-
Tune’s classic pitch adjustment technology
still provides the optimum results. Formant
Correction is designed to be used with overall
transposition or on tracks where notes are
shifted by large intervals.
ANOTHER NOTE: Formant Correction
is not available in the TDM versions
of Auto-Tune Evo. If you wish to use
the Formant Correction function on a TDM
system, be sure to select the RTAS version of
Auto-Tune Evo.
Throat modeling (Native versions only)
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
