Scale
Detune
The Detune
parameter
allows you to
change the
pitch standard of Auto-Tune 7 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.
It should be noted that this control functions
differently in Automatic and Graphical modes:
AUTOMATIC MODE In Automatic Mode, the
Scale Detune control shifts the pitch reference
by the set amount.
GRAPHICAL MODE In Graphical Mode, the
Scale Detune control shifts the position of
the horizontal graph pitch reference lines (or
lanes, if Show Lanes is selected), such that any
correction objects created or adjusted relative
to those reference lines will reflect the Scale
Detune setting.
VERY IMPORTANT NOTE: If you
create any pitch correction objects
and subsequently adjust the Scale
Detune setting, this will NOT change the output
pitches of the existing objects. If you will be
working in Graphical Mode on a track that
requires scale detuning, set the proper detune
amount BEFORE beginning pitch correction.
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 7 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 7 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.
