Reviews of the Top 5 Free Autotune Plugins

These are the 5 best free autotune plugins we reviewed. We go over their main features and pros, as well as some of the drawbacks so you know exactly what you’re buying.

MAuto Pitch

For visualization and customization, MAuto Pitch is the best free plugin we tried out.

It has a range of features that improve music production on many levels, including fine-tuning sets, configuring formats, and enhancing performance.

The first thing you’ll notice about MAuto Pitch is its interface. Its modern, intuitive visuals are easy to interpret but also organized with the options at your disposal to make your music production work easy.

Namely, the main features MAuto Pitch excels in are its depth, speed, and tuning controls.

Its depth control features give you enhancement functions that allow you to alter sound depth to your specifications. This includes fine-tuning the pitch to get it exactly the way you want it.


The speed control similarly lets you set the parameters for the program to skip the out of tune sounds, jump around, or smooth it out with transition controls. Both the high and low speeds on the MAuto Pitch plugin give you options to customize your experience.

This multi-functionality and control make MAuto Pitch the best plugin we reviewed.


  • Optimal sound, depth, and speed controls
  • Modern, intuitive interface
  • Enhancement functions that offer tons of customization


  • For the heaviest music production work, MAuto Pitch, which is designed for lighter edits, may not have everything you need compared to premium software options


GSnap is a popular option when it comes to vocal pitch tuning and other various effects and is well-known for its adeptness in altering vocal sounds.

Of course, it can mix and produce for instruments as well, but it’s in the vocal range that GSnap shines and may top your personal list if those functions appeal to you and your work, though it doesn’t quite top ours.

The user interface, both in graphics and controls, is easy to use. It has two sides so you can view the original and updated pitches, as well as a MIDI control box that allows you to input and link notes to the track you’re working on.

GSnap has features in the program that guide you through the work that needs to be done, taking you to the areas that need work on its own.

It’s a multifunctional app as well, with 12 control knobs that help you edit effects with a lot of customization. Speed and vibrato knobs are particularly useful, allowing you to use pitch detection and manipulation to make the music sound more organic and in tune.

The gate and threshold knobs are also useful, allowing you to pitch-shift at will and adjust the sound detection so that the plugin reads the sounds differently depending on what you’re producing and for what medium.

This multi-functionality makes GSnap a great alternative pick that might be the top pick for those that focus on thresholds or who want a plugin that emphasizes voice controls.


  • Pitch tuning and effects are more varied than the average plugin
  • The interface is sparser than some modern applications but still intuitive
  • 12 control knobs give you a ton of features to play with


  • GSnap is not available for Mac


For voice conversion, KeroVee is a great choice.

It comes with a ton of tools and functions that can help you manage pitch correction to your specifications and replace organic voices with mixed mechanical equivalents.

This applies to instruments as well, which can be autotuned on KeroVee as well as on many premium applications.

The display is broken into two sides, which show the initial and mixed signals and allow you to fine-tune the results with knobs on the display.

Pitch adjustment is accurate on KeroVee even to demanding specifications and is perfect for formatting, panning, and transposing sounds.

Its MIDI controller can detect notes automatically and give you corrections that you don’t even need to input manually. Its calibration and nuisance knobs let you remove discrepancies, adjust vibrato, and set the plugin’s correction speed.

KeroVee’s plugin guides and automatic correction software are finetuned for professional autotuning work.


  • Autotuning software offers optimal control
  • The interface is simple but functional
  • Numerous fine-tuning knobs give you customization and functional pitch shifting, formatting, and calibration options


  • KeroVee is built to finetune vocals, not as much for overhauling huge multi-track instrumentations, so some producers may prefer another plugin

Graillon 2

Best Free Autotune Apps For Iphone

Auburn Sound’s Graillon autotune plugin hasn’t always been free, but Graillon 2 gives you its premium features at no cost to you.

The Graillon 2 plugin has to be the top choice for autotuning in metallic or robotic sounds with its smooth correction module controls that can adjust the speed of sound changes.

You’ll notice right away that Graillon 2 has a classy interface with a nostalgic color scheme and large decorative font. The central display gives you access to the current sound and intuitively helps you see how the program is correcting it.

Graillon 2 has inertia and speed knobs that reduce pitch correction. It also has a bitcrusher function that gives you access to distorted and robotic sounds that are specific for certain compositions.

The growl sound functions and bitcrusher combined with the vintage interface make Graillon 2 a compelling classic experience with a lot of features.


  • A perfect plugin for autotuning metallic sounds and turning voice samples into artificial sounds
  • Nostalgic, high-end interface appearance and intuitive controls
  • Bitcrusher function gives you multifunctional distortion options
  • Growl sounds and other knobs round out a versatile plugin package


  • The lack of semi-tone jumps and some tricky pitch-shift dial options can take some getting used to for some users

AAS Autotune

We’ve talked about the interfaces on each of these autotune plugins but AAS Autotune is our pick for the best plugin that has no interface at all.

This means that you can only set one correction parameter at a time, but the plugin still works well for certain needs.

Auto Tuning App

For tuning fast sounds, especially robotic ones like autotuned vocals in pop tracks, AAS Autotune works well for the most simplified functions possible.

For some tuning, this can be a useful application, especially if you don’t want to mess with a ton of features.

AAS Autotune can be turned on and do its thing without you nursing it so if your goal is to use software to truly “auto” tune the sounds, AAS Autotune might be the choice for you.

Another bonus to the lack of an interface is that it takes up almost no processing power on your computer, freeing it up for other tasks if you want to work on something else.


  • Low RAM requirements make it easy to run with other applications
  • True automatic tuning makes it easy to set up and run without messing with a ton of features
  • Fast tuning for metallic sounds or hectic pop tracks is easier with AAS than doing it manually with something else


  • No interface means no frills and fewer options for customization – just make sure you know what you’re getting into

5 Best Free Autotune Plugins: Buying Guide

This buying guide summarizes the main features you should be looking for when comparing these and other autotune plugins.


The first thing to look for is a plugin that features an interface you can use, since it won’t matter what features it has if you can’t use it efficiently.

Some have classy interfaces like Graillon 2’s decorative font style and some don’t have any interface at all: AAS Autotune, for instance, is just a program that you run on your computer and doesn’t have any windows or extra features.

This gives you a wide array of choices when you’re looking at the interfaces that might work for you.

Since you’re probably using this plugin for work, you need something that you can spend hours on, view the options you need easily, and make your sound design changes with as little hassle as possible.

The good news is that since all these plugins are free, you could theoretically try them out one at a time until you find one you really like.

Control features

How each plugin plays on the traditional features of autotune programs will go a long way to determining which is the right application for your needs.

MIDI controllers, speed, vibrato, gate, and other function knobs (as well as various autotune effects) give the plugins their own identity.

They go from pure minimalism to ultimate multi-functional style tools with as many as 12 knobs to view on increasingly complex interfaces.

What you want to accomplish with this plugin, from voice manipulation to instrumentation conversion, needs to be compared to the desired effects themselves and will largely affect which plugin you choose.


Compatibility is something to check on any plugin before you try and incorporate it into your workspace. GSnap, for instance, isn’t compatible with Mac operating systems.

Some require more RAM than others to run successfully (consider AAS Autotune, for instance, whose minimalism makes it an easy application to run on any computer).

Compatibility may not be on your list of desired features but it’s essential by nature to consider when you’re making your decision.


This category is separate from the features because, in addition to looking at what the plugins can specifically do, you need to look at how you intend to use them to choose the right one.

For example, one plugin may have more features but may lack another’s accuracy in terms of specific conversions of natural voices to robotic effects or adding vibrato, or another specific function you may need.

You need to compare your intentions to the features to know which plugin will work best for you.


As stated, all these plugins are free, so this is no concern here.

The Takeaway

Free autotune plugins can be extremely useful additions to any audio mixer or music producer’s toolkit.

Usually, they come at a price, which is why we assembled this list of the 5 best free ones you can use to mix and tune music and sounds without paying a high premium.

Many of these plugins feature versatile features, control knobs, clever interfaces, and tons of customization options.

One of them (AAS Autotune) doesn’t feature any of these things but instead offers a streamlined approach to autotune plugins that lets you run applications quickly and without the hassle of figuring out bells and whistles. No matter which you choose, you’ll be choosing correctly.

Even still, the wealth of options makes MAuto Pitch our top choice for free autotune plugins because of its wealth of features, beautiful interface, and options for fine-tuning compositions to exact specifications.

No matter if you choose one of these or a brand of your own, use our buying guide to compare the main features so you can match the plugin to your audio production needs.

Autotuning complex compositions is difficult but it doesn’t have to be expensive – use this guide to get a premium autotune plugin for your software arsenal without spending a dime.

Last Updated on October 15, 2020 by

Auto-Tune is everywhere and everyone is using it…

From slight pitch correction to some cool robotic sounds, pitchcorrection software can be extremely useful.

T-Pain made this effect very popular, but it’s also beenused by a lot of other artists such as Daft Punk, the Black Eyed Peas, andmore.

Auto-Tune can be used to achieve a lot of different effectsand you don’t need to spend hundreds of dollars on the Pro version of theSoftware since there are a lot of free ones available.

In this post I’ll go over the best free pitch correctionplugins available for Windows, Mac and even Linux.

Let’s get started!

Related: I also wrote an Article about the best Pitch-correction/auto-tune plugins in general, not just free ones.

1. GSnap – (Windows)

GSnap is one of the best free pitch correction plugins outthere…

The reason behind this is because of its capability tocontrol the notes that it snaps to through MIDI.

This means that if you need to corrects a singer’sperformance through pitch correction you can play the notes on a piano and feedthese notes into the plugin…

GSnap will now use those notes as a guide and will correctthe pitch to whatever notes are in the MIDI file.

This will also prevent unwanted snapping to other notes.

If you don’t want to control the plugin through MIDI, thenyou can set any scale you’d like or control it by turning certain notes on oroff.

The interfaceis fairly easy to use and understand:

On the left you can see the original notes and the ones it’ssnapping to, which will not only give you a visual representation of what’sgoing on…

But also allow you to fine tune everything more easily.

It has a 12-knob control system which is divided in thefollowing way;

Detection: Min Freq, Max Freq, Gate, and Speed knobs.

Correction: Threshold, Amount, Attack, and Releaseknobs.

MIDI: Pitch bend, Vibrato, Vib Speed, and Calibrateknobs.

All of these knobs allow you to edit everything withprecision and accuracy.

One thing I find very useful in this plugin is the gate…

The gate gives you the ability to select on what parts theplugin actually affects the sound…

E.g. If you only want to affect the louder parts, or moreimportantly, if you don’t want the plugin to trigger on any unwanted noises onthat track and just the vocals.

This is an incredible plugin, especially since it’s free andit can do anything from robotic sounds all the way to a very subtle correction withoutbeing noticed.

You can download it here.

2. Graillon2 – (Win/Mac)

The first thing you will notice when looking at Graillon2,is the way its interface is designed…

It has this vintage vibe to it which is just fantastic tolook at.

It’s a very intuitive plugin to use and its color schemewhich makes it easy to navigate.

It is a very visual plugin since it has a display where youcan see the notes that are being played as well as where Grallion2 issnapping/correcting them to.

This plugin is specifically designed for vocals and thepitch shifting can be smoothly adjusted from minus 12 to plus 12 semitones.


One cool feature is the “preserve formants” knob which, intheory, helps you preserve the tone and characteristics of the vocal trackwhile shifting the pitch.

In some cases, this ends up creating some issues, so makesure to play around with these settings to see what happens.

The speed knob is also pretty useful since it helps thenotes “stick” a little longer, reducing the pitch correction jumps.


However, don’t go overboard with this effect since notes canend up sticking too long…

Grallion2 also allows you to choose how fast or slow thesnapping occurs; this is done by adjusting the “smooth” knob.

Basically, it allows you to control how fast the notes willjump from one another.

By adjusting the controls on the “bitcrusher” section, youshould be able to achieve some pretty cool growl sounds.

The typical controls such as dry/wet, low-cut and outputlevel adjustment are also included.

Lastly, the Pitch Correction module can be drivenby MIDI, just like with GSnap.

If you like the vintage look on this plugin and you need agood all-rounder, then Graillon2 may be the one for you.

There is one important note though: It’s notcompletely free but rather “freemium”.

Basically, you won’t get its full functionality unless youbuy it.

With the free edition you only get the “pitch shifting” and“pitch correction” features.

If you want the full version then it will set you back about$25.

You can download it here.

If you’re looking for the best free VST plugins in the world, I have a list of 225 of them.

3. MAutoPitch – (Win/Mac)

Melda Productions is a renowned audio plugin company thatcreated other free plugins such as the MRing Modulator, the MFlanger, MTremolo,and more…

You can find all these plugins in another post I wrote aboutthe bestFree Modulation Plugins.

Even Deadmau5, who is a very famous electronic musician,uses these plugins, which is a testament to their quality.

This plugin comes with the typical pitch correction softwareoptions such as depth, detune and speed…

However, it also includes some additional controls such as a dry/wet knob, a width knob which will allow you to control the stereo spread, and the keep- and shift-formants knobs.

You may not know what shifting the formants does, so here’sa really quick explanation:

It allows you to make the sound deeper or higher, in otherwords “more masculine or feminine”…

However, keep in mind that this can alter the pitch if yougo too far.

MAutoPitch allows you to choose between different scales so that you can quickly adjust it to your song…

These scales are;

Chromatic, major, minor, and pentatonic.

It also provides you with a visual display of what notes arebeing detected by the plugin.

Even though it does have some amazing features and isdefinitely worth using, there are some cons to it:

First of all, the free version comes with a banner onthe bottom that is a bit annoying to look at…

If this isn’t something that annoys you too much, then byall means download it!

Also, the pitch correction isn’t the best since there’s someunintentional snapping to unwanted notes…

Even after you set the notes and the scales perfectly andall the settings are in place.

The MAutoPitch plugin also includes a limiter which shouldhelp you keep your sound from clipping.

All in all, it’s a great free plugin that could make a greataddition to your arsenal!

4. KeroVee – (Windows)

KeroVee was created back in 2010 by the Japanese company“g200kg”.

The whole point behind this software was to create a superprecise vocal pitch adjustment plugin without focusing too much on the othereffects that can be achieved; like a robotic sound.

This is why KeroVee is an excellent alternative for anyonewho just wants to apply some subtle and precise adjustments to their vocaltracks.

Similar to Gsnap and Graillon2, you have the option to routethe MIDI notes to KeroVee.

This will allow the plugin to use these notes as a guide andcorrect them properly which is essential to tell the plugin exactly what notesthe singer should be on.

On the left you can see which notes are being played and whereKeroVee is correcting them to.

Using MIDI to guide the plugin is great, however this mighttake some time to set up…

This is why KeroVee also allows you to select which notesyou want it to correct to, or not, through a simple clickable interface…

Simply click on them to enable or disable them and that’sit!

KeroVee shares a lot of parameters with most other autotuneplugins, however there is one that’s unique to it which is the “nuance”one;

The “nuanceknob lets you select whether ornot to keep the vibrato of the original sound, making the vocals sound morenatural while still being autotuned.

Note: If set to max, even the smallest vibrato willtrigger the correction, resulting in a mechanical sound.

There are loads of other typical controls and functionsavailable with this plugin like Tunespeed, formant shifting, panning, volume,etc.

Like I mentioned earlier, KeroVee is excellent for finetuning the vocal track and doesn’t really emphasize too much on achievingrobotic sounds, etc.

If this is what you need, an autotune plugin designed fordetailed vocal adjustment, then definitely check this one out!

5. X42 Auto-Tune – (Win/Mac/Linux)

X42 Auto-Tune is intended to correct the pitch of a voicesinging (slightly) out of tune.

It works by resampling and looping the signal and does notinclude formant correction, which means that it should be used to correctsmall errors only and not to really transpose a song.

Best free autotune apps for windows

Even though it is a very simple pitch-correction plugin, itactually does a decent job at what it’s supposed to do.

The interface is very easy to navigate; however, it doesn’tlook too great, at least not when compared to Graillon2, but this doesn’t meanthat it’s at all complicated to use.

Just like with GSnap and Graillon2, X42 Auto-Tune can becontrolled via MIDI and it will adjust the pitch to whatever notes youset it to.

If you don’t want to go through all the work of laying downa MIDI track, you can input a fixed number of notes in any key and the pluginwill correct to the notes on that key.

It comes with a “Bias” knob which controls how longthe original note lasts before it corrects it to either the ones youselected from the scale or the ones input through MIDI…

This allows it to go off-tune more than would be the caseotherwise.

The “Bias” control is essential since it won’t instantlysnap the notes to the one selected on the scale, giving it a more naturalsound.

Similar to the “Bias” control you also have the option touse the “Offset” control…

This one gives you the option to adjust how far from thenote the singer is allowed to go before it corrects it.

Both of these parameters are designed to keep the vocalrecording sounding more human and natural.

If you’re looking for a very simple and easy to usepitch-correction tool that focuses mainly on subtle changes, then X42 Auto-Tunemight be a great alternative for you.

You can download it here.

6. Auto-Tune Evo – (Windows)

Auto-Tune Evo by Antares Audio Technology has been releasedin February of 2018 and has been raising in popularity ever since then.

It’s got a great set of features such as pitch correction inreal time, for live performances, vibrato controls and Humanize.

Auto-Tune Evo was created, like most auto tune plugins, withvocals in mind…

However, it works great with most monophonic instruments;e.g. bass.

It has two basic modes; Automatic and Graphical.

With Automatic Mode you give Auto-Tune some basicinformation about the track and that’s it, it will do the rest.

With the Graphical Mode you can go through the entiretrack manually and tell Auto-Tune exactly where it needs to apply somecorrection and how much.

While using the Graphical Mode might be a lot morework and definitely not for everyone, in my experience I’ve found that you geta much more transparent sound.

The common artifacts associated with tuning tend to be lessnoticeable.

Automatic Mode is excellent if you’re going for that T-Painstyle of sound, or if you just want to quickly adjust a track…

While Graphical Mode, on the other hand, will definitelygive you better results if you don’t want the effect to be as obvious and ifyou need to have more control over it.

It really comes down to what sound you’re going for and howmuch time and work you want to invest into it.

Regardless of what mode you’re going to be using, the firstthing you’ll need to do is set up the “Input Type”.

The Input Type control gives Auto-Tune some informationabout the track that it’s going to work with…

The Input Types are; Soprano, Alto/Tenor, Low Male,Instrument and Bass Instrument.

Another feature is the Key and scaleselection where you can tell Auto-Tune the precise key of the song.

Lastly, the Formants control will keep as much of theoriginal characteristics of the vocals if switched on.

Auto-Tune Evo is just great, and it’s free…

If you want a versatile and good-sounding plugin which is goodfor both beginners and advanced producers, then definitely give it a try.

You can download it here.

7. AutoTalent – (Linux)

If you’re a Linux user, then this one’s definitely for you!

Autotalent is an open-source and real-time pitch correctionplugin which allows users to specify the notes that the singer should behitting…

Autotalent will make sure that they do.

Not only can it correct the pitch but it can also be used tocreate such effects like the T-Pain effect.

This will make the vocals sound more like a chiptune.

Even though the interface looks extremely simple, thisplugin is quite powerful…

You can use it for some light pitch correction or to achievea full robotic auto-tune.

It includes all of the typical parameters as otherauto-tune plugins such as; Formant shifting, selecting a scale or notes for theplugin to use or to exclude, and more.

However, it provides one feature that most auto-tune pluginsdon’t… The Vibrato section.

This section can help you add some vibrato to thevocals to give it a more natural sound.

All in all, Autotalent is an extremely useful and completeauto-tune plugin, plus it’s for Linux users who have a lot fewer alternativeswhen it comes to plugins and music production software.

You can download it here.

8. Voloco – (Windows, Mac)

If you’re looking for an Auto-Tuner that is capable of slight- and in-depth correction, then Voloco might not be the right one for you.

It’s designed to be used as a creative tool, which is why you only get access to 6 presets that you can’t even edit and that’s it.

Each of these presets affects the audio in a slightly different way.

However, they are all optimized to achieve the “T-Pain” auto-tuned vocals.

Naturally, since it doesn’t feature any more controls than changing the presets, setting the Key and adjusting how much correction you want, Voloco is extremely easy to use.

The interface is super clean and easy to understand which, if you’re new to auto-tuners, is great news.

Voloco is a fun plugin to have, especially for coming up with new ideas, but it’s not the most in-depth auto-tuner.

Still, I find it easy to recommend!

Lastly, you can also download a mobile version for your phone that you can use to sing over other songs you have on your device and Voloco will adjust your voice to the song’s key.

You can download it here.

Top 3 Choices

Out of all the Auto-Tune plugins on this list I’d have tosay that Graillon2, GSnap and Auto-Tune Evo are my toprecommendations.

They offer a lot of features, they sound great, and they give you more control over the track itself than most other plugins.

Learn how to use AutoTune properly

Even though there’s nothing wrong with learning how to use this kind of software all on your own, learning from someone can be quite useful as well.

Here’s a course about vocal music production where they also teach you how to use Autotune, Vocoders, etc.


Quality software doesn’t necessarily need to come at apremium price…

All of the plugins on this list are more than capable ofdelivering excellent pitch-correction while still offering other features…

And all of this completely for free…

Since they are free, I’d recommend you try them all out andchoose the one that suits your needs the most.

I hope this information was useful!

Have a great day!
