This article features the best free autotune VST plugins. For more software categories, return to Free VST Plugins.

Autotuned vocals are omnipresent nowadays. You can hear them in any style of music, from the latest chart-topping singles to demo tracks by indie artists.

Autotune effects are even used in live performances. The vocal pitch correction functionality that was once exclusive to the Antares Auto-Tune Pro ($399) plugin is now available to everyone, thanks to the existence of free autotune alternatives.

If you’re running a music production studio on a tight budget, our list of freeware autotune VST plugins for PC and Mac will help you keep your vocals pitch-perfect. All you’ll need is a digital audio workstation that can host VSTs.

Pitch correction can be used to subtly correct the pitch imperfections in a vocal recording. It can also change the vocal timbre more obviously, as a creative sound design tool. The latter scenario is also known as “the Cher effect,” made famous by Cher’s song “Believe.”

Regardless of your pitch correction requirements, the autotune alternatives listed below will be capable of substituting the original Auto-Tune plugin by Antares.

Graillon 2 Free Edition by Auburn Sounds

Graillon 2 Free Edition is the best free autotune VST plugin on the market. Its pitch correction module is so efficient and easy to use that we had to place it in the number one spot on this list. It is also compatible with all the digital audio workstations capable of loading VST and AU plugins, both on PC and Mac computers.

Autotuning vocals with Graillon 2 couldn’t be any easier. Simply place it as an insert effect in your vocal mix channel (or you live vocal processing chain), turn on the Correction module, and you’re good to go. Those who require more control over the pitch correction process can limit the note range to a particular scale, adjust the pitch correction speed, and define the pitch correction algorithm’s note detection range.

Thanks to its intuitive and efficient control scheme, Graillon 2 can be fine-tuned to sound more or less artificial, depending on the stylistic requirements of your project. The mix knob on the right-hand side of the user interface can be used to further reduce the impact of the pitch correction module where needed.

On the other end of the realism spectrum, you can use Graillon 2’s excellent pitch shifter module in tandem with its pitch correction algorithm to come with some unusual sounding vocals. For example, you can mix the dry vocal with the autotuned signal, but also add some pitch shifting with preserved formants to the mix. This will effectively thicken the vocals, adding depth and slightly correcting the pitch at the same time.

MAutoPitch by MeldaProduction

MAutoPitch is in no way a less capable Antares Auto-Tune alternative than Graillon 2. Whereas the pitch correction features are roughly the same between the two plugins, MeldaProduction’s product adds a few bonus tools like stereo width adjustment, automatic gain control, and a limiter. The pitch correction algorithm is flexible, with adjustable speed, range, scale, and depth. The added stereo widening feature can be a neat bonus in a vocal processing chain but do make sure to double-check your mix in mono when using it.

That said, the main reason why MAutoPitch isn’t the highest ranked autotune effect on this list is the fact that it comes with a rather cumbersome installer. All MeldaProduction’s freeware plugins, including MAutoPitch, are packed into a single installer file. This results in unnecessarily long download times and a somewhat cumbersome installation procedure. Also, the plugin’s user interface is slightly less intuitive than Graillon’s, but your mileage may vary.

Those few drawbacks aside, MAutoPitch is a brilliant free autotune VST that could quickly become your go-to pitch correction tool. Just as Graillon 2, it is compatible with all VST and AU plugin hosts on PC and Mac.

GSnap by Graham Yeadon

GSnap is the first-ever free autotune VST plugin. It was the first freeware VST plugin that was able to achieve the classic autotune effect. Back in the day, such software tools were still somewhat of a rarity.

In terms of its features and design, GSnap is still a fantastic pitch correction plugin. At first look, it seems very similar to Graillon 2 and MAutoPitch. One excellent feature that sets it apart, though, is the ability to tune the processed audio signal according to the MIDI notes on the input. In other words, you don’t have to rely on the plugin’s automatic pitch detection algorithm. Instead, the user can feed the correct MIDI notes into the plugin and let it take care of the rest. GSnap’s automatic pitch detection algorithm does a great job as well, although without the formant shifting features found in Graillon 2 and MAutoPitch.

Unlike Graillon 2 and MAutoPitch, GSnap will only work on Windows-based systems. It does come with a very well-written manual, though. The instructions are worth a read if you decide to use GSnap as your go-to pitch correction tool.

KeroVee by g200kg

KeroVee is another old-school pitch correction tool, released way back in 2010. Although it looks somewhat less slick than the previous three autotune VSTs on this list, KeroVee’s feature set is right on par with the competition. In fact, it also features the MIDI input mode seen in GSnap.

Whereas this feature isn’t all that useful if you’re going for the Cher effect, it can be quite convenient if you want absolute control over the pitch of the vocals in your track. In a way, it is closer to what you’d get with Melodyne. But apart from that, KeroVee can also operate in full auto mode, just like the previously mentioned Graillon 2 and MAutoPitch.

One area in which KeroVee doesn’t shine, though, is system compatibility. It will only work as a VST plugin in Windows-based digital audio workstations, so macOS users are out of luck here.

Voloco by Resonant Cavity

Voloco is a simple free autotune VST that was designed to used exclusively as a creative tool. Don’t expect to achieve subtle vocal pitch correction with Voloco. This is an intentionally robotic-sounding autotune plugin for use in electronic and urban music.

Budget-Friendly Autotune Plugins

A budget-friendly autotune plugin that won’t break the bank is Auto-Tune Access by Antares. If you’re looking for something more advanced, give iZotope Nectar 3 a try. Another interesting vocal processing tool, although more of a pitch shifter than a pitch correction plugin, is the excellent Little AlterBoy by Soundtoys. For complete control over the pitch correction process, try using Waves Tune.
