Chapter	2: 	Introducing 	Auto-Tune 	5
Some background 
In 1997, Antares Audio Technologies first introduced the ground-breaking Auto-Tune Pitch Correcting Plug-In. Auto-Tune was a tool that actually corrected the pitch of vocals and other solo instruments, in real time, without distortion or artifacts, while preserving all of the expressive nuance of the original performance. Recording Magazine called Auto-Tune a “holy grail of recording.” And went on to say, “Bottom line, Auto-Tune is amazing…...



The twelve equally-spaced tones of the Equal Tempered Scale happen to contain a number of intervals that approximate integer ratios in pitch. The following table shows these approximations: 
INTERVAL CENTS NE ARBY R ATIO IN
   R ATIO  CENTS  
minor second 100  16/15  111.75  
major second  200  9/ 8  203.91  
minor third  300  6/5  315.64  
major third  400  5/4  386.31  
perfect fourth  500  4/ 3  498.04  
tritone   600  
perfect fifth  700  3/2  701.65  
minor sixth  800  8/5  813.69

How Auto-Tune 5 detects pitch 
In order for Auto-Tune 5 to automatically correct pitch, it must first detect the pitch of the input sound. Calculating the pitch of a periodic waveform is a straightforward 
process. Simply measure the time between repetitions of the waveform. Divide this time into one, and you have the frequency in Hertz. Auto-Tune 5 does exactly this: It looks for a periodically repeating waveform and calculates the time interval between repetitions. 
The pitch detection...

Automatic Mode 
Auto-Tune 5’s Automatic Mode works by continuously tracking the pitch of an input sound and comparing it to a user-defined scale. The scale tone closest to the input is continuously identified. If the input pitch exactly matches the scale tone, no correction is applied. If the input pitch varies from the desired scale tone, an output pitch is generated which is closer to the scale tone than the input pitch. (The exact amount of correction is controlled by the Retune Speed and...



Retune SpeedAuto-Tune 5 also gives you control over how rapidly, in time, the pitch adjustment is made toward the scale tone. This is set with the Retune Speed control (see Chapter 3 for more details). 
•  Fast Speed settings are appropriate for 
short duration notes and for mechanical instruments, like oboe or clarinet, whose pitch typically changes almost instantly. A fast enough setting will also minimize or completely remove a vibrato, as well as produce the infamous “Cher effect.” 
•...



Graphical Mode 
The Graphical Mode is similar to the Automatic Mode in that it also continuously tracks the pitch of the incoming sound and modifies the output pitch to be closer to a desired pitch. But in the Graphical Mode, the desired pitch is not a predefined scale tone, but rather is a graphical representation of your desired pitch. 
As in Automatic Mode, the rate of change towards the desired pitch is controlled by the Retune Speed control. 
The key feature of Graphical Mode is the...



The Graphical Mode also includes the Envelope Graph, which displays the amplitude (loudness) envelope of the sound whose pitch is shown in the Pitch Graph. The horizontal scale of this graph will either 1) show the envelope of the entire extent of the pitch-detected sound or 2) align with the horizontal scale and position of the Pitch Graph above it. 
In Graphical Mode, you can draw the desired target pitches using line and curve drawing tools or selectively modify the existing pitch...
