Chapter 2: Introducing Auto-Tune 3
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......

To take maximum advantage of the power of Auto-Tune 3, you should
have a basic understanding of pitch and how Auto-Tune 3 functions to
correct pitch errors. This chapter presents basic terminology and intro-
duces Auto-Tune 3’s operating paradigm, giving you information you need
to use it effectively.
A little bit about pitch
Pitch is typically associated with our perception of the “highness” or
“lowness” of a particular sound. Our perception of pitch ranges from the
very general (the high pitch of...

Some pitch terminology
The pitch of a periodic waveform is defined as the number of times the
periodic element repeats in one second. This is measured in Hertz (abbre-
viated Hz.). For example, the pitch of A3 (the A above middle C on a
piano) is traditionally 440Hz (although that standard varies by a few Hz. in
various parts of the world).
Pitches are often described relative to one another as intervals, or ratios of
frequency. For example, two pitches are said to be one octave apart if
their...

As you can see, the intervals in the Equal Tempered Scale are NOT equal to
the harmonious integer ratios. Rather, the Equal Tempered Scale is a
compromise. It became widely used because once a harpsichord or piano is
tuned to that scale, any composition in any key could be played and no
one chord would sound better or worse than that same chord in another
key.
How Auto-Tune 3 detects pitch
In order for Auto-Tune 3 to automatically correct pitch, it must first detect
the pitch of the input sound....

How Auto-Tune 3 corrects pitch
Auto-Tune 3 provides two separate and distinct ways to approach pitch
correction: Automatic Mode and Graphical Mode. The basic functionality
of each is described below.
Automatic Mode
Auto-Tune 3’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...

11
Scales
The heart of Automatic Mode pitch correction is the Scale. Auto-Tune 3
lets you choose from major, minor, chromatic or 26 historical, ethnic and
microtonal scales. Individual scale notes can be bypassed, resulting in no
pitch correction when the input is near those notes. Individual scale notes
can also be removed, allowing a wider range of pitch correction for
neighboring pitches. The scale can be de-tuned, allowing pitch correction
to any pitch center.
For added flexibility, you can also...

An Example of Automatic Mode Correction
As an example, consider this before-and-after graphic representation of
the pitch of a vocal phrase that contains both vibrato and expressive
gestures.

ORIGINAL
PERFORMANCE CORRECTED BY 
AUTO-TUNE 3
In the original performance, we can see that although the final note
should be centered around D, the vocalist allowed the tail of the note to
fall nearly three semitones flat. The “after” plot is the result of passing
this phrase through...

13
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 control.
The key feature of Graphical Mode is the Pitch Graph display....

14
The horizontal grid lines represent scale pitches. The key annotation, scale
name, scale pitches and Scale Detune value are those defined in the
Automatic Mode. They do not affect the computations of the Graphical
Mode in any way. They are merely a reference to guide you in setting the
target pitches. If you wish to change them, you can select the Automatic
Mode and change the Key pop-up, Scale pop-up, or the Scale Detune
setting, respectively. (Changing the Scale Detune setting will also result in...
