The default Tracking setting is 25. Double-clicking the Tracking knob will

reset it to that value.

Note: The improved pitch detection algorithm in Auto-Tune 3

(in combination with the new Input Type selection described

above) results in noticeably more reliable pitch detection

compared to previous versions of Auto-Tune. If you have used

older versions of Auto-Tune, you may find that situations that

previously required constant modifications of the Tracking

control now track perfectly at the default setting.

The Vibrato Section

The Vibrato Section contains one pop-up and three

knobs. The Vibrato pop-up allows you to select the

shape of the vibrato’s pitch variation. The choices are:

(no vibrato), sine wave, square and sawtooth. Depth,

which controls the amount of pitch variation in the

vibrato, varies from 0 to 100 cents. The Rate varies from

.1 to 10.0 Hz and controls the speed of the vibrato.

Delay varies from 0 to 3000 milliseconds, controlling the

speed of onset of the vibrato. For example, if it is set to

1000, the first 500 milliseconds of a new tone will

contain no vibrato and the next 500 milliseconds will

make a transition from no vibrato to the full vibrato.

The vibrato is re-started every time the Auto-Tune 3

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.

Note: Although we perceive vibrato primarily as a variation in

pitch, in most cases there is also a matching variation in ampli-

tude. Setting Auto-Tune 3’s Retune Speed to 0 will remove an

existing vibrato’s pitch variation, but the amplitude variation

will remain. If you then apply a new vibrato using Auto-Tune 3’s

Vibrato section, the results may be less than convincing. Auto-

Tune 3’s Vibrato section is more often useful for adding a

vibrato to an input that originally had none, or for various

special effects.
