Autotune is a piece of digital software which modifies the pitch of a singer’s vocal. This can be used either during a live performance, or in post-production. In recent years, autotune has progressed from subtle changes in vocals to the main identity of musicians such as T-Pain, Daft Punk, Black Eyed Peas and Cher. Typically used in pop music, many will be able to identify an artist by the distinct autotuned sounds. Consequently, there are a variety of autotune and pitch tuning plugins available. However, many cost a lot of money and finding the right one to do the job for your needs can be overwhelming. To help you out, we’ve put together a list of our top free autotune plugins that are still functional. Check out the list of what to consider when looking for your perfect plugin!

Free Autotune Plugins

There are a few things to consider when looking for an autotune plugin, such as what sound you want to achieve. Are you looking for minor corrections for a natural sound? Then maybe a pitch correction plugin with a transparent audio engine would be best. Or would you rather a plugin which allows you to draw in the notes for a singer/instrument to hit? This is usually suitable for hip-hop or certain electronic genres. Alternatively, you may require effects to allow you to further customise the voice and may need MIDI input. Whatever you need, check out the list below:

The Best Free Autotune Plugins

Graillon 2 Free Edition

No list of autotune plugins would be complete without the free version of Auburn Sounds’ Graillon 2!

It is one of the best autotune VST free download plugins out there. Also, it is compatible with all the digital audio workstations able to load VST and AU plugins, on PC and Mac computers. Its pitch correction module is very efficient and simple to use. With its stand-out looking interface including large fonts and prominent colours, it is easy to navigate. It is also a well-programmed plugin, which enables both substantial autotune and fine pitch correction functions perfectly!

Auto Tuning vocals with Graillon 2 is incredibly easy, thanks to its intuitive and proficient control scheme. You can fine-tune your sound less or more artificial, depending on your musical requirements. The mix knob on the user interface can be used to reduce the impact of the pitch correction module. You can also create robotic sounds by using the ‘smooth’ knob. This controls how slow/fast your sound skips from one note to another. The ‘bitcrusher’ area can make a voice growl and reinforce a bass portion of monophonic pitched sounds. This is a unique function to Graillon 2! It can also act as a pitch-shifting plugin with the pitch wheel. Equally, you should be careful when using the functions that some notes don’t ‘stick’ for too long and alter the melody.

If you need impeccable, versatile functionality with extra features and are wondering how to get autotune for free, Graillon 2 is the one for you.

MAutoPitch

MeldaProduction is a well-known audio plugin business. Their products add a few bonus tools like stereo width adjustment, automatic gain control, and a limiter.

All MeldaProduction’s freeware plugins, including MAutoPitch, are crammed into a single installer file, which is quite cumbersome. The pitch correction algorithm is flexible, with adjustable speed, range, scale, and depth but the user interface is slightly less perceptive than Graillon.

MAutoPitch is still a great free autotune plugin that could quickly become your go-to pitch correction tool. The ‘speed’ knob controls how quick MAutoPitch will respond to out-of-tune notes, allowing smoother sounds. Shifting formants can make you sound deeper or higher but be careful altering the formant too much can alter its pitch.

The benefits to this plugin are the wealth of bonus features, and it is compatible with all VST and AU plugin hosts on PC and Mac. The visual detector displays which notes are being detected by the plugin. The scale function allows you to detect which scale of music you’re in. This means that MAutoPitch will only adapt the pitch to the perfect notes according to the key of the track.

With a variety of features available, high functionality and easy interface MAutoPitch is a great choice.

GSnap

Gsnap free autotune

One of the first free pitch correction plugins, GSnap, is among the best. It was the original freeware VST plugin that accomplished the classic autotune effect. To this day, GSnap is still a great in terms of features and design.

One main feature is its ability to tune the processed audio signal according to the MIDI notes on the input. If you aim to correct a singer’s notes, play their part on a piano and use the MIDI notes from the piano in the plugin, GSnap will take those notes as a guide to make it accurate. Many plugins can’t achieve this but it’s an extremely beneficial tool!

The original sound is in red, and the altered notes are emphasised in green. Twelve fully adaptable knobs give exact editing of the effect. Also, this plugin allows you to add vibrato and adjust the speed of it, essentially making the vocalist sound more organic.

Unlike Graillon 2 and MAutoPitch, GSnap only works on Windows-based systems. It does come with a very good manual, so it’s worth reading the instructions if you decide to use GSnap. GSnap is renowned amongst experienced producers for its versatility, MIDI feed options as well as easy interface, so give it a go!

KeroVee

Another original pitch correction tool, KeroVee was released in 2010 by Japan based g200kg. Although it looks less slick than its competition, the feature set is matched. Likewise, it has the MIDI input mode like GSnap.

KeroVee may lack in the extreme robotic effects, but it more than makes up for it with accurate pitch alteration capabilities. On the left side, there’s an easy scaled interface so you can see exactly what KeroVee is doing and react suitably. Just to the right of this, you can click which notes of the scale you want KeroVee to adjust to. Selected notes will have a green block next to them, while deselected notes will be black.

Just like GSnap, you are also able to route MIDI notes to KeroVee for the plugin to use as a guide. This is a vital element which lets you tell KeroVee exactly which notes the singer should be on, with a large set of knobs to customise further. Unique feature is the ‘nuance’ parameter. It enables you to keep or ignore subtle pitch changes, such as natural vibrato from the singer. Just like other autotune plugins, you get a ‘TuneSpeed’ knob to control how quickly the plugin will fix the incoming audio.

The ‘calib’ function checks the general pitch of the sound. Other important functions include pitch and formant shifting, fine tuning as well as panning and volume knobs. The main downfall of KeroVee is system compatibility. It only works as a VST plugin in Windows-based DAWs, meaning that macOS users won’t be able to use it.

If you are hoping for an autotune plugin which is tailored exactly for adequate modification of vocals instead of a severe and noticeable effect, KeroVee is a great option.

Autotune Free Online & Free Autotune Software

As an alternative to plugins, Melodyne is a great free autotune software. Melodyne is a tool which allows you to control pitch, timing and formant of an audio track. This is particularly good for vocals, but can also be used for when you are recording bass, guitar, piano.

Musical notes can be softened or heightened electronically for perfect recordings. Melodyne is fully compatible with older types of audio media including vinyl. Melodyne allows people who recorded their voice in older formats to retrieve it, and even adapt their vocals to create fresh new sounds. If you are good at using technology then Melodyne is great to get creative with. Although it can be difficult to master, there are a lot of great features and effects.
