Antares Auto Tune 4 Features:
A revised core pitch detection algorithm that greatly improves pitch detection
reliability in both Automatic and Graphical Modes.
"Source Specific" pitch detection and correction algorithms. Choices include
Soprano Voice, Alto/Tenor Voice, Low Male Voice, Instrument, and Bass Instrument.
Matching the appropriate algorithm to the input results in even faster and more
accurate pitch detection and correction.
Phase-coherent pitch correction of stereo tracks.
A Bass Mode that lowers the lowest detectable frequency by about one octave to
25Hz. Since the lowest E string on a bass guitar is approximately 41Hz, Bass
Mode allows the user to apply pitch correction to fretless bass lines as well
as other low bass range instruments.
The ability to set target pitches in real-time via MIDI from a keyboard or sequencer
track.
A new Make Scale From MIDI function for occasions when it is not clear exactly
what key a melody line is in, or where the line has too many accidentals to fit
comfortably into a conventional scale. For those occasions, the Make Scale From
MIDI function allows you to simply play the line from a MIDI keyboard or sequencer
and let Auto-Tune 3 construct a custom scale containing only those notes that
appear in the line.
High sample rate (88.2kHz, 96kHz) compatibility (depends upon host application
and audio hardware support).
TDM and RTAS versions compatible with Pro Tools|HD
*Enhanced MIX chip usage efficiency for more instantiations per MIX chip (TDM
only)
AudioSuite version (TDM only)
If you already use Auto-Tune, you're going to want Auto-Tune 3. It's as simple
as that.
Auto-Tune 3. They made it better because they just couldn't help themselves.
Auto-Tune 3 is available in TDM, MAS, RTAS, Mac VST, and DirectX versions. Upgrades
are available for current Auto-Tune owners.
Pitch Detection
Both the Automatic and Graphical modes start by instantaneously detecting the
original pitch of a performance. This detection requires a periodic waveform,
typical of a lead vocal or other solo instrument. The pitch detection algorithm
is virtually instantaneous. Used in combination with a slight delay of about
5 milliseconds, the detected pitch can be corrected, without artifacts, to the
desired pitch.
Pitch Correction
As the input pitch is detected, Auto-Tune's proprietary pitch correction algorithm
changes it to the target pitch at a user-selected rate. The Auto-Tune algorithm
is extremely clean and transparent and introduces no distortion in the output.
Over a typical pitch correction range, it is simply not possible to tell that
a sound has been processed, except that it is perfectly in tune.
Automatic Mode
Auto-Tune's Automatic Mode works by continuously comparing the detected input
pitch to a user-selected Scale. The input is constantly corrected to the Scale
note that is closest to the detected input pitch.
The rate at which the input pitch is slewed to the target pitch is controlled
by the Retune slider. The choice of Retune rate depends on the style of the performance
and amount of required correction. A fast Retune rate, for example, is appropriate
for a performance with rapidly-changing pitches or where substantial correction
is required. A slower rate will preserve expressive gestures while accurately
adjusting the pitch center to be in tune.
All aspects of the Automatic Mode Scale can be optimized for a particular performance:
You can select any key and scale s minor, major, chromatic, and 26 historical
and microtonal scales provide unprecedented control of the output tonality.
Specific Scale notes can be removed, allowing a wider range of pitch correction
for neighboring notes.
Individual Scale notes may be "bypassed," meaning that when the input pitch is
near that note, the input is passed through with no correction. Having trouble
hitting a single note? Bypass all the rest of the Scale notes, and Auto-Tune
will only apply correction to the problem note.
The Scale can be de-tuned, allowing pitch correction to any desired pitch center.
The Vibrato section lets you add a vibrato to a performance with variable depth,
rate, and onset delay.
All buttons and sliders are automated under Pro Tools 4.0 or later.
Graphical Mode
Most peoples' experience is that Automatic Mode solves most pitch problems most
of the time. But for those times when only the most meticulous tweaking will
do the job, Auto-Tune offers Graphical Mode.
In Graphical Mode, the you can use a variety of graphic tools to actually draw
your target pitches as a function of time. Data entry is made easy by displays
showing the performance's amplitude envelope and the detected pitch referenced
to the Scale selected in Automatic Mode. Simply draw a horizontal line at the
desired pitch or, for more elaborate processing, convert the detected pitch graph
to a fully manipulatable curve. Complete image sizing and scrolling controls
are provided. The graphical editor allows easy editing, including cut, copy,
and paste functions. Graphical Mode also includes a Retune function identical
to that in Automatic mode.
The Professional Standard
Auto-Tune is used daily by thousands of audio professionals around the world.
Whether to save studio and editing time, to ease the frustration of endless retakes,
or to save that otherwise once-in-a-lifetime performance, Auto-Tune is the tool
of choice. Check it out. And prepare to be amazed.
