Auto-Tune is one of the most widely used plug-ins in music production. This tutorial shows you the power within this amazing audio processor.
In the 22 years since it's inception (1997), Auto-Tune has been the industry standard for tuning vocals, and for good reason. From my own personal experience, it's still my go-to tuning software, as it can keep up with my own workflow, and does exactly what I need it to do. There are many other tuning softwares available, but none have the proven to me better. In the past 20 years, I've never had a single negative comment, or even anyone notice that I've used a tuning software, which is exactly as it should be. There are many people out there wanting to lay blame on the tools for their work sounding robotic, or unnatural. I may take some heat for saying so, but this doesn't have to be the case if you learn how to use your tools properly; pay attention to what the settings do. If something doesn't sound right, keep tweaking until it does. It's as simple as that. Now I must say though, there is a limit to how much tuning or editing you CAN do to a less than perfect performance. A common saying in the industry comes to mind - 'You can't polish a turd'. I could probably write an entire book on tuning vocals, but the intent here is to give you an inside look at the most commonly used parameters and how to use Auto-Tune in a more effective way….

The Correction Modes In Auto-Tune
There are two correction modes and ways to use Auto-Tune. There's Auto Mode, also know as 'lazy mode', and Graphical Mode, also known as 'Auto-Tune'. Auto Mode basically runs in real-time, and analyzes the audio as it passes through. It then determines what to do to the audio, as it passes through. Adjusting your settings can help it to do a better job of tuning, but nothing replaces your own ears on what needs to be tuned, and what does not. The only time I personally use Auto Mode is when I have several songs that need to be mixed in a very short amount of time, and there simply is not enough time, or budget, to properly tune the tracks. Graphic Mode is a bit more involved, but yields MUCH better results! Graphic Mode basically works like this: You capture (track pitch) the performance once into the plug-in, so it can be analyzed, displayed and edited. (Same for most other professional tuning software) Then, you choose which notes are to be tuned, and how, and which are to be left alone. This is far superior to every single bit of audio being automatically adjusted. By the way, if what you are trying to achieve with Auto-Tune is the T-Pain, or CHER effect, use Auto Mode with a very fast Retune Speed, and you can skip the rest of this article.
Auto Mode
Auto Mode is the default mode when opening Auto-Tune. It is designed to automatically analyze audio as it passes through, and tune up or down to the nearest note everything that passes through. With that being said, there are some very important things to pay attention to, as they will help you get much better results. Paying attention to a few of these settings following, you can minimize Auto-Tune attempting to tune things that should not be, such as vibrato and notes that are intentionally slurred from one note to another.
Input Type: This basic setting help Auto-Tune focus on specific frequency ranges and types based upon the type of content you are trying to tune. Always start here!
- Soprano -For high or female voices
- Alto/Tenor -For normal voices
- Low Male -For Barry White
- Instrument -For violins, violas, and other types of monophonic instruments
- Bass Inst -For lower pitched instruments, and yes, it is quite common to tune a bass guitar.
Scale: Setting the scale to the actual key of your song will most certainly help minimize errors in automatically tuning. Chromatic is the default scale, and probably most popular, but setting the proper key of your song will narrow down the choices of tuning from eleven notes down to the seven within a given key. For example, you have a song in the key of 'C', which has no sharps or flats. A singer sings a little bit sharp on a trying to sing a 'C'. If the note sang is closer to 'C#', Auto-Tune will try to tune the note up to 'C#', resulting in an improperly tuned note. When setting the scale to C Major in this same scenario, the singer would have to sing past 'C#' for it to create and error and try to correct to a 'D'. This is another great starting point for Auto Mode usage. As you can see from the picture to the right, there are many other scales to choose from, and yes, Auto-Tune is used world wide, and there are many other scales available to those around the world using alternate tuning and scales.
Retune Speed: This is one of the most important settings to pay attention to, as it sets how fast Auto-Tune will tune a note, similar to a glide or fade time from non-tuned to fully tuned processing. Setting a very fast time will remove any variations in pitch, but can yield some very unnatural results. But then again, this is a big part of creating the T-Pain/Cher effect. If this is what you are looking for, absolutely start here with a very fast time!
Humanize: This allows sustained notes to have a slower Retune speed than the shorter duration notes. Typically you would start a setting of 0 while setting the Retune speed, making sure all notes that need tuning are being tuned, then adjusting the Humanize will help with sustained notes from not sounding overly tuned, while still being fast enough to tune shorter duration notes.
Natural Vibrato: This is independent of your pitch settings and is used solely to tame natural vibrato of a performance. Leaving it at it's default setting of 0, will not affect the original vibrato, but adjusting will minimize the amount of vibrato allowed. Once again, this is independent of pitch controls.
Targeting Ignores Vibrato: Turning this on can help with what Auto tuning tries to tune and what it ignores. If you have a track with a lot of vibrato, try turning this on and see if it helps. This is something that would typically be used with a lead type of vocal, allowing the natural vibrato to be ignored. Backing vocals typically shouldn't have as much vibrato, therefore, minimizing vibrato is preferred.
Target Notes Via MIDI: This is quite fun to play with, along with fast Retune speeds. When engaging, Auto-Tune does nothing until a MIDI note is present from a keyboard or MIDI track, then it tunes to the MIDI notes present. You can then play in a melody from a MIDI device, and the track will be tuned to what you play.
Graphic Mode
Graphic Mode is the mode you will use the most often when quality is the primary concern. The advantage: Graphic mode allows you to specify which notes are to be tuned, and which are not, along with independent settings for each note to be tuned, instead of the global settings to be used for every note passing through in Auto Mode.

Correction Mode to Graph: Pretty self-explanatory, slide or click the correction mode from Auto to Graph.
Options
Click on the options button next to correction mode to get here:
Enter buffer seconds: The default here is 240 seconds, which is 4 minutes at 44.1k or 48k sample rate, based upon your session settings. A minute song would require 300 seconds. There's no need to set a really high buffer amount, as it uses much more RAM from your system. The max setting of 14400 would yield 4 hours on one track! If any of you actually need that much, I'd like to know what project you are working on.
Default Retune speeds: After learning a bit about retune speed from Auto Mode, you can set the default retune speeds for various tune settings in which I will discuss shortly here, but this is where you set your defaults.
Track Pitch in Autotune
The first thing we need to do is capture, or 'Track Pitch', our audio track into Auto-Tune so that it can analyze it, draw a graphic representation of the audio pitches, and respond appropriately. This allows Auto-Tune the time to not only respond quickly, but also to ramp in tuning before a note needs to be tuned, which is impossible in Auto Mode, as it is only running in real-time. So to get started:
- Click on the 'Track Pitch' button: It will turn 'Red' when enabled to track pitch.
- Play the track: Play your song from beginning to end, or section by section. As long as all the information that needs to be tuned is tracked in, you can then proceed.
- Turn off the 'Track Pitch' button: Self-explanatory, but necessary to start tuning.
Decisions decisions!
You have two options now for tuning. You can draw or auto-create lines/curves or notes. The difference is that notes are typically easier to work with and treat an area of audio as a block, or note, and a line or curve allows you to treat bends in between specific notes with a little more intent.
The Tools
There are a few tools to start with here and I'll describe them briefly from left to right.
- The Line Tool is used to draw multi-segment lines on the pitch graph. It is typically used when you want to hold a straight pitch, or bend evenly from one pitch to another.
- The Curve Tool is used when you would like to free-hand draw in pitch correction. I personally find this one quite difficult to use.
- The Note Tool is used to draw notes. These are constrained to specific pitches and cannot vary off of them. I tend to use these more often than the line tool.
- The Arrow Tool is the most commonly used tool, as it is how you select and edit existing lines or notes.
- The Scissors Tool is used to cut existing lines or notes into separate pieces for individual editing. I typically use this when notes or lines have been generated automatically, and need to be separated. We'll take a look at automatically generating lines or notes shortly.
- The Magnifying Glass is used for zooming. Simply click and drag a box around what you would like to zoom into, and release to zoom.
- The I-Beam Tool is used to select an area of time to be used edit with in, or generate data between. This is also a commonly used tool.
- The Hand Tool is used to move the display. Click and hold on an area of the screen, and then drag the screen to an area you would like to see. I find the scrolling functions on apple mice work quite nicely for this same purpose, so this one doesn't get used much.

Manual Editing/Drawing of Lines and Notes in Auto-Tune
In this example above, after capturing (Track Pitch) a vocal into Auto-Tune, I selected the Line Tool, and then clicked on 'Snap to Note' which forces any segments of a line to snap to a specific note. Upon clicking the last segment, it must be double-clicked to end the line. After drawing this line, it is still selected, and retune speed can be set for this line independently of other lines. If it is not selected for some reason, using the Arrow Tool, click on the line to re-select it, and then you can adjust the retuning speed. The advantage of using the Line tool is that, as shown, the bend from one note to another can be drawn in as well.
In this example to the below, I selected the Note Tool, and then drew in some notes. I've found that drawing notes from where they are on key, or crossing through the desired key, on the beginning and end of a note give the best results. The advantage of the working with Notes is that Notes can be moved from one pitch to another much easier than trying to move a line.
Automatically creating Lines and Notes in Auto-Tune
Select an area: Using the I-Beam Tool, select an area that you wish to generate notes or Lines/Curves> Personally, I like to select the duration of the entire song, and then fix the points that are not created to my satisfaction, rather than manually create each event, one by one.
Down at the bottom of the plug-in next to 'Track Pitch' are the option for 'Make Curve' and 'Make Notes', which are how we can auto-create 'Notes' or 'Line Curves'.
Make Curve: Clicking the Make Curve button will automatically draw a curved line, matching exactly the pitches captured in from the Track Pitch function earlier. As you can see to the right, there are green lines overlapping the detected pitches, and anchor points on either side of each detected event. These anchor points can be moved independently by clicking on, and dragging each anchor point up or down. This is particularly useful is in key, but starts drifting sharp or flat as a note is being held out. You need to use the Arrow Tool to manipulate these points.
In the example below, an area was first selected using the I-Beam Tool, then using the Arrow Tool, the Curves were moved up together to another pitch, keeping all the bending between notes still intact. If only part of a curve or line is to be moved, the line can be separated into two segments by clicking at the desired split point using the Scissors Tool. Now the segments can be individually manipulated.
In the example below, the 'Make Notes' button was pressed after selecting the same area as described above. The advantage with working this way is that the only things being tuned, or manipulated are the notes that are being sustained, and the bending in-between notes is left alone. I find it particularly advantageous to modify these notes using the Arrow Tool. What I've found to give the best results is to drag the edges of each note to a crossing point, where the original audio is on, or crossing through, the correct pitch. By starting and stopping the tuning process on these points that are already in tune, I've found that I have much more transparent tuning, and less 'T-Pain' sounding tuning.
Hopefully this is enough to get you started in Auto-Tuning, and has shed some light onto the mysterious world of tuning. Honestly, Auto-Tune has saved so many projects from bankrupting, and allowed thousands of productions to keep amazing performances, that in the past would have been performed over, and over, and over, and over again, until finally in key. Did anyone happen to think about the feeling, or emotion, left in a recording that an artist just finished singing for the 150th time? Yes, it may finally be perfectly in tune, but is the emotion of the singer still representing the initial idea of the song, and convincing all the listeners that this is a happy song. I think Elvis left the building about 145 takes back…. My point is, if a take sounds and feels great, but has a little pitch problems here and there, it's worth tuning vs. beating the life out of a part until it is performed technically correct.
Until next time, happy tuning!

What I find most fascinating about Antares Auto-Tune is that everyone and their mother knows what it is, despite the fact that it's just another digital audio plugin used in bedroom and professional studios alike. Even people who have no clue what an EQ or compressor does somehow at least know of the word 'Auto-Tune' and even the general effect it has on the human voice.
But even though Auto-Tune has evolved to become this cultural phenomenon, very few artists or producers truly understand how to get it to sound like the way it sounds on major records.
In case you don't know what it is, Auto-Tune, in a nutshell, is a pitch correction software that allows the user to set the key signature of the song so that the pitch of the incoming signal will be corrected to the closest note in that key (and does so in real time). There are other pitch correction programs out there that do similar functions: Waves Tune, Waves Tune Real-Time, and Melodyne (which is pitch correction, but not in real time), but Auto-Tune seems to have won the standard for real-time pitch correction.
Auto-Tune traditionally is used on vocals, although in some cases can be used on certain instruments. For the sake of this article we will be discussing Auto-Tune and its effect on the human voice. Listen to this early example from the 'King of Auto-Tune,' the one artist who did more to popularize its effect than any other, T-Pain.
Working as a full-time engineer here at Studio 11 in Chicago, we deal with Auto-Tune on a daily basis. Whether it's people requesting that we put it on their voice, something we do naturally to correct pitch, or even for a specific creative effect. It's just a part of our arsenal that we use everyday, so over the years we have really gotten to know the ins and outs of the program—from its benefits to limitations.
So let's delve further into what this software really is and can do, and in the process debunk certain myths around what the public or people who are new to Auto-Tune may think. If you were ever wondering why your Auto-Tune at home doesn't sound like the Auto-Tune you hear from your favorite artists, this is the article for you.
To set the record straight, as I do get asked this a lot of times from clients and inquiring home producers, there really are no different 'types' of Auto-Tune. Antares makes many different versions of Auto-Tune—Auto-Tune EFX, Auto-Tune Live, and Auto-Tune Pro—that have various options and different interfaces, but any of those can give you the effect you're after. Auto-Tune Pro does have a lot of cool features and updates, but you don't need 'Pro' to sound pro.
I wanted to debunk this first, as some people come to me asking about the 'the Lil Durk Auto-Tune,' or perhaps that classic 'T-Pain Auto-Tune.' That effect is made from the same plugin—the outcome of the sound that you hear depends on how you set the settings within the program and the pitch of the incoming signal.
So if your Auto-Tune at home sounds different from what you hear on the radio, it's because of these factors, not because they have a magic version of Auto-Tune that works better than yours at home. You can achieve the exact same results.
In modern music Auto-Tune is really used with two different intentions. The first is to use it as a tool in a transparent manner, to correct someone's pitch. In this situation, the artist doesn't want to hear the effect work, they just want to hit the right notes. The second intent is to use it as an audible effect for the robotic vocals you can now hear all over the pop and rap charts.
But regardless of the intent, in order for Auto-Tune to sound its best, there are three main things that need to be set correctly.
The correct key of the song. This is the most important part of the process and honestly where most people fail. Bedroom producers, and even some engineers at professional studios who might lack certain music theory fundamentals, have all fallen into the trap of setting Auto-Tune in the wrong key. If a song is in C major, it will not work in D major, E major, etc.—though it will work in C major's relative minor, A minor. No other key will work correctly. It helps to educate yourself a bit about music theory, and how to find the key of a song.
The input type. You have the option to choose from Bass Instrument, Instrument, Low Male, Alto/Tenor, and Soprano. Bass Instrument and Instrument are, of course, for instruments, so ignore them if you're going for a vocal effect. Low Male would be selected if the singer is singing in a very low octave (think Barry White). Alto/Tenor will be for the most common vocal ranges, and soprano is for very high-pitched vocalists. Setting the input type correctly helps Auto-Tune narrow down which octaves it will focus on—and you'll get a more accurate result.
Retune speed. This knob, while important, is really all dependent on the pitch of the input source, which I will discuss next. Generally speaking, the higher the knob, the faster it will tune each note. A lower speed will have the effect be a bit more relaxed, letting some natural vibrato through without affecting a vocalist's pitch as quickly. Some view it as a 'amount of Auto-Tune knob,' which isn't technically true. The amount of correction you hear is based off the original pitch, but you will hear more effects of the Auto-Tune the faster it's set.
So let's say you have all of these set correctly. You have the right key, you choose the right range for the singer, and the retune speed is at its medium default of 20ms. You apply it on the singer expecting it to come out just like the pros. And while their voice does seem to be somewhat corrected, it's still not quite corrected to the right pitch.
Here's why your Auto-Tune doesn't sound like the pros:
The pitch of the vocalist prior to Auto-Tune processing must be close enough to a note in the scale of the key of the song for Auto-Tune to work its best. In other words, the singer has to be at least near the right note for it to sound pleasing to the ears.
Whether you're going for a natural correction or the T-Pain warble, this point still stands. If the note the singer originally sings is nowhere near the correct note in the key, Auto-Tune will try to calculate as best it can and round up or down, depending on what note is closest. And that's when you get undesirable artifacts and hear notes you weren't expecting to hear. (Here is an example of how it sounds when the incoming pitch isn't close enough to the scale, resulting in an oddly corrected pitch.)
So if you put Auto-Tune on a voice and some areas sound good, some sound too robotic and a bit off, those are the areas that the singer needs to work on. Sometimes it can be difficult for non-singers to hear slight sharp or flat notes, or notes that aren't in the scale of the song, so Auto-Tune in many cases can actually help point out the problem areas.
This is why major artists who use Auto-Tune sound really good, because chances are they can sing pretty well before Auto-Tune is even applied. The Weeknd is a great example of this—he is obviously a very talented singer that has no problem hitting notes—and yet his go-to mixer, Illangelo, has said before that he always uses at least a little bit of Auto-Tune on the vocals.
If you or the singer in your studio is no Weeknd, you can correct the pitch manually beforehand with a program like Melodyne, or even with built-in pitch correction tools in your DAW, where you can actually go in and change the pitch of each syllable manually. So if you find yourself in a situation where you or an artist you are working with really want Auto-Tune on their vocals, but it's not sounding right after following all the steps, look into correcting the pitch before you run it through Auto-Tune.
If you get the notes closer to the scale, you'll find the tuning of Auto-Tune to be much more pleasing to the ears. For good reason, T-Pain is brought up a lot when discussing Auto-Tune. Do you want to know why he sounds so good? It's not a special Auto-Tune they are using, its because he can really sing without it. Check it out:

Hopefully this helps further assist you in your understanding and use of Antares Auto-Tune, and debunk some of the myths around it. Spend some time learning some basic music theory to help train the ear to identity keys of songs, find which notes are flat and which notes are sharp. Once you do, you'll find you'll want to use Auto-Tune on every song, because let's face it—nearly a decade after Jay-Z declared the death of Auto-Tune on 'D.O.A.'—it still sounds cool.
