The autotuning industry (does an industry like that exist?) is booming. If you turn on the radio, you can hear autotune on almost every track.

Strangely, the options in the free autotune VST plugin market are still few...

But the ones available are sufficient for your autotuning needs. Whether your goal is making your vocals sound like T-Pain or if you want natural results – these free autotune plugins will work fantastic.

Let’s dive into the list.

Graillon 2 (by Auburn Sounds)

Do you want to ensure that your vocals are singing perfectly in tune? The Graillon 2 autotune is as powerful as it is beautiful.

With many different settings, including different pitch tracking modulations, corrections, pitch shifting, and bit crushing, you have everything you need to mix perfect vocals.

Let’s say you have a vocal sample that sings a bit off-tune.

Throw the Graillon 2 on your vocal and set your scale. Now, the autotune forces all the notes outside the scale to be perfectly on point.

You also get additional features like vocal doubling for extra harmonics, which creates a cool chorus-like effect for greater fullness.

Great free autotune VST plugin and a must-have for vocal mixing producers.

MAutoPitch Autotune (by Melda)

MAutoPitch Autotune is a great effect for those who want the classic T-Pain autotune effect. But also, if you want a natural pitch correction result.

Select your scale and key from the simple interface. Then, play around with the depth and speed knobs.

If you max out both, you get the crazy autotune effect commonly heard in top hits. Dial the settings down, and you get a more natural result – and a vocal perfectly in tune.

A cool thing about this free autotune plugin is that you get additional effects to control your sound. Add some formant shift, increase the width or double your autotune with your original vocal.

If you want an autotune that is simple to use with great results and interesting effects – the MAutoPitch is definitely for you.

KeroVee (by g200kg)

If you don't care about a completely natural result using autotune but want a distorted pitch effect – the KeroVee is a great alternative.

Select your tuning mode by scale or MIDI and choose your tune speed, nuance, and amount. Now, the pitch correction is starting to work its magic. Especially the tuning speed setting determines how robotic and digital your result is.

Try putting it on singing vocals or snippets to get the classic powerful autotuning effect. You can also try using it on other instruments, like guitars or drums.

Producers dig it for its ease of use and ability to take dull sounds and transforming them into something more. With the ability to play your autotuned sound and the original, you can also get the cool ‘backing vocal’ effect.

The KeroVee autotune is a great plugin that definitely deserves a spot on the list.

GSnap (by GVST)

GSnap is a simple-to-use, and highly effective free autotune effect that transforms off-key vocals to flawlessness.

Depending on the settings you use, you can use it as a natural autotune with little to no artifacts. Or you can go extreme – creating an autotune effect so heavy that it will surprise Mr. T-Pain himself.

Start by choosing your scale. Then, you have two very important features of GSnap – the Min and Max Freq knobs and the Gate. T

he frequency parameters tell GSnap where it should focus its autotune, giving you much more accurate results if you focus it on the foundational vocal frequencies.

The Gate sets the threshold for the audio it should affect. That means you don't get any weird autotuning going on in silent pauses or background noises – only your vocals.

This free autotune VST plugin is truly one to own with a clean interface and powerful autotuning engine.

Summary

Almost every famous singer uses autotune on their mixed vocals, to different degrees.

Autotuning vocals is a love or hate thing for most people. But often, it comes down to singers using excessive autotune to hide their real voice.

Most people don’t have a problem with autotune if they don’t notice it’s there...

If you use it as a cool effect or very mildly to ensure that your vocals hit the right notes, it’s a fantastic musical tool that makes your mixes better.

With these free autotune VST plugins, you have four great effects you can try out.

Remember, don’t be afraid to experiment in music.
