Create Vibrato Functions
The controls in this section are designed to add
a synthesized vibrato to the input.
While vibrato is typically perceived to be a
variation solely in pitch, careful analysis shows
that, depending on the voice or instrument
and the style of the individual performer,
variations in amplitude (loudness) and formant
resonances are also involved. Reflecting
this, Auto-Tune 8 includes a plethora of
vibrato functions to allow the creation of
much more convincing vibratos. (And for the
adventuresome, they can be abused to create
some “interesting” eects.)
The controls are:
Shape
Selects the
shape of the
vibrato.
The choices are:
NO VIBRATO Pretty self-explanatory.
SINE WAVE Changes smoothly from
minimum to maximum and back again. The
most common choice for a conventional
vibrato.
SQUARE Jumps to maximum where it spends
50% of the cycle and then jumps to minimum
for the remaining 50% of the cycle.
SAWTOOTH Gradually rises from minimum
to maximum and then drops instantaneously
to minimum to start the cycle again.
Rate
Sets the rate of the vibrato over a range of 0.1
Hz to 10 Hz. The default Rate setting is 5.5 Hz.
Double-clicking or Command (Mac)/Control
(PC) clicking the Rate knob will reset it to that
value.
Variation
Sets the amount of random variation that
will be applied to the Rate and Amount
parameters on a note to note basis. Useful for
humanizing the vibrato by adding random
“errors.”
The range is from  (no variation) to 100
(maximum variation). The default Variation
setting is 20. Double-clicking or Command
(Mac)/Control (PC) clicking the Variation knob
will reset it to that value.
Onset Delay
Sets the amount of time (in msec) between
the beginning of a note and the beginning
of the onset of vibrato. The range is from 
to 1500ms (1.5 seconds). The default value is
500ms. Double-clicking or Command (Mac)/
Control (PC) clicking the Onset Delay knob will
reset it to that value.
