a slower Retune Speed just to the sustained
notes. Thus, the short notes are in tune and the
sustained notes still allow the natural variations
of the original performance.
Here’s how it works:
Start by setting Humanize to 0 and adjusting
the Retune Speed until the shortest problem
notes in the performance are in tune. At
this point, any sustained notes may sound
unnaturally static. If so, start advancing the
Humanize control. The higher the Humanize
setting, the more the Retune Speed is slowed
for sustained notes. The goal is to find the
point where the sustained notes are also in
tune and just enough of the natural variation
in the performance is present in the sustained
notes to sound natural and realistic. (If you set
Humanize too high, any problem sustained
notes may not be fully corrected.)
This is one of those settings where you
have to let your ears be your guide. The
optimum Humanize setting for any particular
performance will depend on the performance
style, the other Automatic Mode settings and
the specific effect you desire.
The default Humanize setting is 0. Double-
clicking or Command (Mac)/Control (PC)
clicking the Humanize knob will reset it to that
value.
Natural
Vibrato
The Natural
Vibrato
function
allows
real-time
modification
(either
increase or decrease) of the depth of any
vibrato present in the input audio while
preserving the original shape and character of
the vibrato.
This function uses the same Stochastic Optimal
Linear Estimation Theory as the Targeting
Ignores Vibrato function (described below) to
differentiate between vibrato and intended
pitch changes, adjusting the vibrato depth while
leaving intended pitch changes intact.
The Natural Vibrato function acts independently
of the pitch correction functions. Of particular
note is the fact that setting a scale note or
notes to Bypass still allows vibrato adjustment
for those notes. So, if you want to adjust a
performance’s vibrato while making no other
pitch changes, you can simply set all scale
notes to Bypass and still use the Natural Vibrato
function to adjust vibrato depth.
NOTE: This function acts only on
vibrato present in the original
performance. If the original
performance does not contain vibrato, this
control will have no audible effect.
ANOTHER NOTE: Natural Vibrato
adjustments function independently
of the Create Vibrato functions
described below. However, since both
functions can operate simultaneously, they can
interact in ways that may or may not be useful,
depending on your intent. In most cases, you
should probably use one or the other.
The default Natural Vibrato setting is 0. Double-
clicking or Command (Mac)/Control (PC)
clicking the Natural Vibrato knob will reset it to
that value.
Targeting Ignores
Vibrato
Target note identification
is the process by which
Auto-Tune decides
which note is the note
the performer intended
to sing or play, so that it may re-tune any pitch
errors closer to that note. Normally, the target
note is the nearest active scale note to the
current input pitch.
The Targeting Ignores Vibrato feature is
designed to help with target note identification
when the performance includes vibrato so
wide that it approaches adjacent scale notes.
The most common symptom of this problem
is a pronounced “warbling” as the input is
alternately tuned to each of the upper and
lower adjacent notes.
When this function is ”On,“ Auto-Tune Evo
uses the impressively named Stochastic
Optimal Linear Estimation Theory to attempt
