Anteras Auto-Tune Pro is an industry standard vocal audio effect that allows us to pitch correct and auto-tune vocal performances.

If you’ve ever heard the auto-tuned style vocals in a pop song, you’ve most likely already heard what Auto-Tune Pro is capable of.

Even if you’re not a traditional singer and want to create your own unique vocal elements in your mix with your own voice, Auto-Tune Pro is a handy tool to have on deck. And as you may have noticed in the intro, you can stretch a vocal performance in either direction pitch-wise, while also shaping the synthetic throat size of the tuned vocal. It’s pretty amazing to say the least.

Global Controls

Input Type = Choose between 5 different processing algorithms that produce slight differences in output depending on the type of incoming audio

// Choices = Soprano, Alto/Tenor, Low Male, Instrument, and Bass Instrument (choose wisely)

Key = Choose the desire key of the tuned audio

Scale = Choose the desired scale of the tuned audio (depending on the key)

Auto Mode = Simple grab and go auto-tune controls

Graph Mode = In Depth auto-tune full control

Classic Mode = Toggle on the classic Auto-Tune 5 sound (deactivates formant, throat, transpose, flex-tune & time editing)

// Use = Create more of the iconic pop song auto-tune sound w/ slightly brighter quality &

Formant = Correct or retune the formants of the incoming vocal which can be helpful for avoiding unnatural or chipmunk-like vocals

Throat = Adjust the shape of the singer’s throat, specifying the synthetic length of the modeled throat

Transpose = Additionally shift the overall pitch of the incoming vocal by semitones (+ or - an octave)

// Tip = Acts as the caboose pitch control when in Graph Mode & won’t effect the output pitch display

Detune = Adjust the pitch reference frequency (440Hz is the pitch standard normally)

Tracking = Adjust the length of the periodic waveform Auto-Tune Pro uses to make pitch decisions

// Tip = Set this to a lower value if you’re hearing any clicks or pops in the retuning of the vocal

Auto Mode

Retune Speed = Adjust the speed of the pitch correction by milliseconds as it’s applied to different portions of the incoming audio

// 400 = Creates more of a natural pitch correction sound

// 0 = Set the this knob to 0 for the classic auto-tune shifting shimmer pitch sound

Flex-Tune = Adjust the subtle vocal gestures of the incoming vocal

// 0 = Correction are is very large, correcting the incoming vocal more aggressively

// 100 = Correction area gets smaller, allowing the incoming vocal to retain any subtle pitch variation that may have been sang intentionally

Humanize = Adjust the realism of the sustained notes when high retune speeds are in play

// Tip = Helps smooth out the timbre for shorter and longer notes (i.e. dynamically applying different retune speeds to the sustained portion of longer notes)

Natural Vibrato = Amplify or diminish the range of vibrato that is already present the vocal performance

Pitch Display = Represents the note or pitch that Auto-Tune Pro is outputting

Pitch Change Meter = Represents the amount of pitch correction in cents taking place in order to reach the desire output note or pitch

Hold = Freeze the pitch change amount where it stands for as long as we hold the button

The Keyboard = Displays the currently detected pitch in real time, represented by the highlighted blue keys

// On = White or black keys, input pitches will be tuned to nearest available note

// Bypass = Orange keys, input pitches will be passed through with no correction

// Remove = Grey keys, input pitches will be tuned to the next closest scale note

Keyboard Edit = Individually remove or bypass keys manually by simply clicking on the note

Keyboard Mode = Adjust the toggle mode for each individual key we want to alter

// Latch = Clicking on a key to change its state is toggled normally

// Momentary = Clicking on a key to change its state is temporarily toggled until let go

Advanced = Toggle on the visibility of the advanced controls


Targeting Ignores Vibrato = Preserve any intentional vibrato in the vocal performance, which may be useful to toggle on if auto-tune is recognizing the vibrato as multiple notes

Shape = Choose the shape of the pitch modulation for the vibrato (during longer sustained notes)

// Choices = No Vibrato, Sine Wave, Square & Sawtooth

Rate = Adjust the speed of the vibrato in Hz

Onset Delay = Adjust the duration of time in milliseconds between the start of the note & when vibrato begins to take place

Onset Rate = Adjust the duration of time in milliseconds between the start of the vibrato & the maximum Pitch, Amplitude & Format values are reached (or full vibrato is reached)

Variation = Adjust the amount of random variation that is applied to the Rate & Amount

// Use = Random deviation helps add in a human feel to the vibrato

Pitch Amount = Adjust the width of the vibrato in cents (pitch modulation width)

Amplitude Amount = Adjust the amount that the loudness changes during the vibrato

Formant Amount = Adjust the amount of formant variation during the vibrato


Edit Scale Display = Create custom scales or modify any of the preset scales

Bypass = Input pitches that are closest to that note will be passed through with no correction

// Use = Apply correction to only specific notes if the performance is 98% good for example

Remove = Remove a note from the scale, directing any incoming pitches that are closest to that note to the next closest scale note instead

// Use = Create a pentatonic scale or you want to restrict notes for really bad/off vocal performances

Cents = Displays each note’s interval in cents from the root note of the scale

Set Major/Minor = Quickly generate a major or minor scale, depending on the key selected (bypassing the keys outside of the scale)

Set All = Set all of the notes to on & return the scale to it’s default setting

Bypass All = Bypass all of the notes in the scale

Remove All = Remove all of the notes in the scale


MIDI Functions = Control many of Auto-Tune Pro’s parameters with a MIDI controller in real time (see preferences for adding MIDI information)

Target Notes = Use MIDI to control the specific pitch that the incoming audio is being tuned to in real time

Learn Scale = Construct a custom scale based on a set of MIDI notes chosen

All Octaves = If toggled on, any incoming MIDI notes will affect all octaves of each note

Graph Mode

Main Graph = Where the pitch and time editing takes place

Track Pitch/Pitch + Time = Track the vocal performance audio into graph mode, ready for editing

// Pitch = Track the pitch of the incoming audio (more efficient if you don’t need time correction)

// Pitch + Time = Track the pitch and time of the incoming audio so we can adjust timing if needed

// Display = Incoming Pitch Contour (red curves), pitch correction & outgoing pitch contour (green curves

Waveform Overview = Navigate our waveform a bit easier & also displays the original waveform vs any time correction applied in comparison (toggle on & off with carrot)

All/Tie Switch = Adjust how much of our tracked audio is displayed in the waveform overview

// All = Position and zoom settings are widened, displaying all of the currently tracked audio

// Tie = Position and zoom settings follows the position of the Main Graph

Zoom States = Quickly toggle between different levels of zoom in the main graph

// Tip = Hold down Option on Mac or Alt on Windows and click on any of the zoom state buttons to save a current zoom setting


Make Curves = Creates pitch correction objects called curves, which we can edit and stretch for a more precise pitch correction

Import Auto = Import any Auto Mode settings we may have used as a good starting point for more precise editing in Graph Mode

Make Notes = Create Note Objects based on an analysis of the tracked audio (edited with tools)

Make Notes From MIDI = Create Note Objects based on MIDI note data that has been tracked in the selected region (see preferences for setup)

Number of Notes = Adjust how Auto-Tune Pro analyzes the incoming audio and what constitutes as a note and where the boundaries are between each new Note Object

// Higher Value = Interpret changes in pitch as new notes rather than slight deviations or expressive gestures within a single note

Retune Speed = (just like Auto Mode) Adjust how rapidly the pitch correction is applied to the incoming audio

// Lower Value (0) = Creates the traditional auto-tune like sound (more abrupt and robotic)

Adjust Vibrato = Amplify or diminish the range of vibrato that is already present in the incoming audio

Throat Length = Adjust the synthetic length of the modeled throat

// Tip = Graph Mode’s Retune Speed, Adjust Vibrato & Throat Length all allow us to adjust specific portions of the incoming audio depending on what is selected

Select All = Selects all correction objects in the graph

Cut = Removes any selected correction objects from the graph and copies them to the clipboard

Copy = Copies any selected correction objects to the clipboard

Paste = Paste any copied correction objects anywhere on the graph

// Tip = Click Paste, Press & hold Mouse Button, Drag objects to location, Release mouse

Clear All = Clear all Pitch Correction Objects, Time Changes, Both Pitch & Time or All Data

Undo/Redo = Undo or redo the most recent edits (up to 20 levels of undo available)

Nudge = Move the currently selected correction objects up or down in precise one pixel increments


Line Tool = Draw straight, multi-segment lines on the Main Graph
