8 Best Autotune Plugins for FL Studio for Free

Pitch correction features that were previously exclusive to the Antares Auto-Tune Pro plugin are now available to everyone, thanks to free autotune alternatives. Here is a nice collection of the best free FL Studio autotune plugins for you to use in your compositions. In addition to FL Studio, these autotune plugins can be used in other DAWs such as Ableton Live, Logic Pro, and VST-compatible software.

Autotune is an indispensable music production tool. You can hear auto-tuned vocals in all genres of music, from the latest chart-topping singles to demos from indie artists.

If your collection of music production software lacks a pitch correction tool, our list of free autotune VST plugins will help you keep your vocals pitch perfect. All you need is a DAW or digital audio workstation that can host VSTs (in this case FL Studio).

Autotune for FL Studio free [Windows and Mac]

In this section, we collect the best autotune plugins for FL Studio that work on Windows and Mac. 

Graillon 2 Autotune VST

Grail 2 is a Vocal Live Changer that brings thoughtfully designed features and a world of possibilities right into your DAW. With Pitch-Tracking Modulation, which is exclusive to Graillon 2, this autotune plugin for FL Studio can change the type of speakers, generate throat sounds, create choruses, make octave sounds, and enrich a voice to make it more masculine.

Grail 2 is the best free autotune for FL Studio on the market. Its pitch correction module is skillful and simple to use. It is compatible with all DAWs capable of loading VST and AU plugins, both on Windows and Mac.

MAutoPitch Autotune

MAutoPitch is an easy but great-sounding automatic pitch correction plugin designed for vocals and other monophonic instruments. In addition to making the audio more in tune, MAutoPitch also offers innovative formatting and stereo expansion features.

The autotune effect is flexible and easy to handle, with adjustable speed, range, scale, and depth. The added Stereo Widening feature can be useful in a vocal processing chain, but be sure to check your mix in mono when using it. Like Graillon 2, it is compatible with all PC and Mac VST and AU plugins.


GSnap is an old free autotune VST plugin. It was the first free autotune on the market. At that time, pitch correction software was still a rarity. Despite the years, GSnap is still a fantastic free autotune plugin. At first glance, it looks a lot like Graillon 2 and MAutoPitch. A great feature that sets it apart is the ability to tune the processed audio signal according to the MIDI notes in the input.

In other words, you don’t have to rely on the plugin’s automatic pitch detection algorithm. Instead, the user can input the correct MIDI notes into the plugin and let the plugin take care of the rest. GSnap is only available for Windows.

These are its main characteristics:

  • Use subtle adjustments to bring out-of-tune vocals back into alignment.
  • Extreme settings can create sounds like the famous T-Pain or Cher effect.
  • MIDI input control mode allows you to set a recording to a new tune.
  • Simple user interface


Oli Larkin’s Autotalent is an excellent real-time pitch correction VST plugin. The Autotalent plugin ensures that only specified notes are played. Also, use this autotune plugin to create Cher-like vocal effects or use it as a simple pitch shift/pitch-correct audio effect. You may need to disable multiprocessor support on your VST host for it to work.

Son of a Pitch

Son of a Pitch is an audio pitch-bend effect. The pitch of the incoming signal can be controlled by the pitch knob or by synchronization with the host LFO. Its pitch knob ranges from +3 octaves to -3 octaves of the original pitch.

The effect also features an LFO-controlled filter section. There are three filters to choose from, 2 SV filters and a Butterworth filter. Filters can be bypassed by sending the dry signal directly to the pitch bender.


KeroVee is another autotune tool that came out several years ago, way back in 2010. Just like GSnap, KeroVee has a MIDI input mode. Although MIDI input is not required for the classic “T-Pain autotune” effect, the function is convenient if you want absolute control over your vocal pitch.

But aside from that, KeroVee can also work in free autotune mode, just like Graillon 2 and MAutoPitch.

However, one area where KeroVee doesn’t shine is system compatibility. It will only work as a VST plugin in Windows-based DAWs, so macOS users are out of luck here.

KeroVee might be the best option for a free autotune plugin if you are using an older DAW on Windows. It uses almost zero CPU resources and works great on older 32-bit systems.

DSP 2 Voice

The Vocal DSP 2 is a high-precision insert effect for vocal processing and also includes an intelligent dynamics processor, a saturator, a four-band EQ fixed at key vocal frequencies, and a Schroeder reverb-based room emulator.

It has been designed to be an easy-to-understand solution for all your vocal processing needs.

  • Intelligent Dynamic Processor (IDP).
  • 4 different automatic operating modes.
  • Selectable compression ratio.
  • Saturator with three different operating modes.
  • Fixed equalization on the key frequencies of the voice.
  • Room emulator based on the Schroeder reverb model.
  • Transparent increase in perceived volume level.
  • High precision input/output VU-meter.
  • Low CPU usage.

Voloco from Resonant Cavity

Voloco is a free autotune plugin for FL Studio that was designed to be used exclusively as a creative tool. This is an intentionally robotic sound autotune plugin for use in electronic and urban music.

Although Voloco is available as a VST3 and AU plugin on desktop operating systems, it is mainly used on iOS and Android. Voloco’s app version is easily the best free autotune for mobile devices.

It’s a good free autotune alternative for beginners who don’t want a plugin with advanced controls. Voloco offers six vocal autotune presets and allows the user to adjust the key of the song and the scale.
