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.
Formant Correction
A sound’s ”formants” are the combined
acoustic resonances that result from the
physical structure of whatever is producing
the sound.
In the case of a human voice, air from your
lungs is forced through your vocal chords,
causing them to vibrate. From there, the
voice is propagated through the throat, the
mouth and out through the lips. It is the shape
of these structures that create the resonant
characteristics that define your unique vocal
identity.
When a vocal is pitch-shifted by large intervals
without formant correction, not only is the
pitch of sung notes shifted, but the formants
are shifted as well. The resulting eect is not
just of a person singing higher or lower notes,
but of a person who is literally growing or
shrinking (depending on the direction of the
shift). While this can be useful for producing
singing chipmunks, it typically does not
produce realistic pitch-shifting over ranges
larger than a semitone or two.
Engaging Auto-Tune 8’s Formant Correction
prevents the shifting of a voice’s resonant
frequencies to ensure that its vocal
characteristics are preserved over the pitch
shift range.
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.
Throat Modeling
As mentioned above, the shape of a singer’s
throat is a prime contributor to their vocal
character. Auto-Tune 8’s Throat Length control
lets you use Antares’ unique throat modeling
technology to modify a voice’s character by
passing it through a precise physical model of
the human vocal tract.
Auto-Tune 8 also includes the ability in
Graphical Mode to individually modify the
throat modeling for each note or correction
object, oering an entirely new level of creative
control.
Time Shifting and Correction
We’ve designed Auto-Tune 8’s time control
capabilities to combine an extremely high-
quality time-shifting algorithm with an
exceedingly intuitive user interface designed to
make it quick and easy to correct timing errors
or exercise your creative imagination.
Time Tracking
In order to do its time shifting magic, Auto-
Tune 8 must first create a copy of the audio
you wish to edit. This is accomplished with the
Track Pitch and Time function. To help manage
this audio data, we’ve provided a convenient
Data File Management dialog that allows you
to establish or move the location of the data
files, rename their folder, as well as delete them
if they are no longer necessary (after bouncing
the final time-modified audio, for example).
The File Management System will also alert
you if the data files are not where Auto-
Tune 8 expects them to be and will provide
information to help you find them.
Time Tools
Although allowing for an enormous amount of
flexibility, Auto-Tune 8’s time shifting functions
make use of two easy-to-use tools; the Move
Point tool and the Move Region tool.
The Move Point tool allows you to select
a range of audio and pick any point in the
range and move it forward or back in time,
compressing and expanding the audio around
it.
