which the vibrato depths will increase from
none to the full amounts set in the various
Amount parameters — for a total of 1.75
seconds from the beginning of the note to the
time full vibrato depth was reached.
Pitch Amount
Sets the amount that the pitch changes. The
range is from 0 (no change) to 100 (maximum
change). The default setting is 18. Command
(Mac)/Control (PC) clicking the slider will reset it
to that value.
Amplitude Amount
Sets the amount that the loudness changes.
For the most realistic vibrato, the amount of
amplitude change should be substantially less
than pitch change, although for special effects,
anything goes.
The range is from 0 (no change) to 30
(maximum change). The default setting is 10.
Command (Mac)/Control (PC) clicking the slider
will reset it to that value.
Formant Amount
Sets the amount that the resonant timbre
changes. The range is from 0 (no change) to
100 (maximum change). The default setting is
70. Command (Mac)/Control (PC) clicking the
slider will reset it to that value.
NOTE: The vibrato is re-started every
time Auto-Tune Evo matches the
incoming pitch to a different scale
tone. Also, the vibrato is applied after the
effects of the Retune Speed control. Hence,
even with a slow retune value of 50, a square
wave vibrato will make instantaneous changes
in pitch.
ANOTHER NOTE: As mentioned
above, although we perceive vibrato
primarily as a variation in pitch, in
most cases there is also matching (though
more subtle) variations in amplitude and timbre.
Setting Auto-Tune Evo’s Retune Speed to 0 will
remove an existing vibrato’s pitch variation, but
the amplitude and timbral variation will remain.
If you then apply a new vibrato using Auto-
Tune Evo’s Create Vibrato section, the results
may be less than convincing. Auto-Tune Evo’s
Vibrato section is more often useful for adding a
vibrato to an input that originally had none, or for
various special effects.
YET ANOTHER NOTE: The Create
Vibrato controls function completely
independently of the Natural Vibrato
function. Changes in that function have no
direct effect on the depth of any vibrato
resulting from the Create Vibrato controls.
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.
