AN IMPORTANT NOTE:
 Over the very 
small intervals usually associated 
with basic pitch correction, formant 
shifting is essentially inaudible and Auto-
Tune’s classic pitch adjustment technology 
still provides the optimum results. Formant 
Correction is designed to be used with overall 
transposition or on tracks where notes are 
shifted by large intervals.
Correction Mode
Click the appropriate 
button to select either 
Automatic or Graphical 
Mode.
The Options Dialog
Clicking the Options button will 
bring up a window containing a 
number of settings that fall into 
the “set and forget” category. 
They are:
BUFFER SIZE  This controls the number of 
seconds of memory buer space that are 
permanently reserved for pitch tracking and 
pitch correction data in Graphical Mode. 
(There is a separate buer for each plug-in 
occurrence.) To change the buer allocation, 
click in the data field and enter the required 
number of seconds.
Th
e maximum buer length is 14,400 seconds 
(i.e., 4 hours).
NOTE: For hosts that provide valid 
time information, Auto-Tune 8 will 
display all tracked pitch information 
at its correct time within the track. If your host 
supports this capability, setting the buer to 
the length of the entire song and tracking the 
pitch in one pass will allow you to quickly and 
easily move to each section of audio to be 
corrected as necessary.
NUMBER OF UNDOS  Auto-Tune 8 provides 
multiple Undo/Redo capability in Graphical 
Mode. Select the maximum allowable 
number here (up to 20). Choosing a higher 
number allocates more memory for saving 
intermediate states.
NOTE: The value selected here 
applies independently to both pitch 
correction Undo/Redos and time 
control Undo/Redos. For example, if you set 
this value to 15, you will have 15 levels of undo 
for pitch correction actions and an additional 
15 levels for time control actions.
KNOB CONTROL  Lets you select how you 
want to control the “knobs” in the Auto-Tune 
8 interface.
LINEAR: Position the cursor over a knob, press 
and hold the left mouse button (or the only 
mouse button, if you’re using a one-button 
mouse) and move the cursor up or to the right 
to turn the knob clockwise or down or to the 
left to turn the knob counterclockwise. The 
current value of the knob’s parameter appears 
in its associated numeric display.
