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 7
uses the impressively named Stochastic
Optimal Linear Estimation Theory to attempt
to recognize vibrato and differentiate between
it and intended note changes. Our testing has
shown that it works a lot of the time — but not
always (it depends a great deal on the actual
performance). When it works, Auto-Tune 7
ignores the wide vibrato as far as target note
selection is concerned. When it doesn’t, it
works pretty much the same way it would
work if the function were ”Off.”
The default state of this control is Off. When
you’ve got a vibrato problem, try turning it on
and see if it helps.
