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 effect 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 Evo’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 Evo’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.
