MAutoPitch for PC: How to Download & Install on Windows

Introduction

MAutoPitch is the free automatic pitch correction plug-in from MeldaProduction, and it is one of the best entry points into vocal tuning on Windows. It is a simple, great-sounding automatic tuner for vocals and other monophonic instruments, with extra creative tools such as formant shifting and stereo expansion built in, and it costs nothing. It is also part of the MFreeFXBundle, MeldaProduction’s large free plug-in collection, so installing it gives you access to many other free tools as well.

This guide explains what MAutoPitch is, how its pitch correction, formant shift and stereo controls work, what your PC needs to run it, and how to download and install it from the official MeldaProduction website only. You will also get a first-use walkthrough that tunes a vocal naturally and then tries the formant shifter for creative effects, so you can hear what the plug-in does. By the end, you should be able to load MAutoPitch in your DAW and tune vocals with confidence.

MAutoPitch is best for singers and producers who want a free, simple autotune-style tool, for beginners learning how pitch correction works, and for anyone who wants formant shifting without buying a paid tuner. Because it is a free MeldaProduction effect, you do not need a cracked copy or an unknown download site. The official website provides it through the MFreeFXBundle installer, and the free plug-in is a real, permanent tool, not a short trial.

What Is MAutoPitch?

MAutoPitch is a free automatic pitch correction plug-in for Windows and Mac, made by MeldaProduction, a Czech developer known for its large range of audio plug-ins. In simple terms, it is a tool that runs inside your DAW as an effect plug-in, and it listens to a vocal or a monophonic instrument in real time, detects the pitch of each note, and gently pulls off-key notes towards the nearest correct note in the key and scale you choose. That is the classic autotune effect, done simply and well.

Besides its main job of making audio more in tune, MAutoPitch provides creative features that many free tuners do not. Formant shift changes the character of a voice without changing its pitch, so you can make a vocal sound deeper, brighter, younger or more robotic, or keep it sounding natural when you shift the pitch a long way. Stereo expansion widens the tuned sound, and a built-in safety limiter keeps the output below 0 dB, protecting your ears and your speakers. It also includes automatic gain compensation, so the output stays as loud as the input even as the correction changes the sound.

MAutoPitch is installed as part of the MFreeFXBundle, which is MeldaProduction’s free bundle of effects, delivered through the MPluginManager installer. The installer lets you choose which plug-ins to install, so you can install only MAutoPitch if you want, or take the whole free bundle. The plug-in is available in VST, VST3, AU and AAX formats, in 64-bit only, and it works in most major DAWs.

Key Features

Free automatic pitch correction: a free effect that tunes vocals and monophonic instruments in real time, with no trial period and no payment.
Formant shifting: change the character of a voice without changing its pitch, for natural-sounding large shifts or for creative vocal effects.
Stereo expansion: widen the tuned sound for a bigger, more spacious vocal in the mix.
Speed and depth controls: set how fast the correction pulls notes into place and how strongly it corrects, from gentle, natural tuning to hard, robotic autotune.
Automatic gain compensation: the output stays as loud as the input, so correction never makes your vocal suddenly quieter or louder.
Built-in safety limiter: a brickwall limiter keeps the output below 0 dB, protecting your equipment and your ears automatically.
MIDI control: send MIDI notes to control the pitch correction in real time, for harmonies and creative tuning effects.
Part of MFreeFXBundle: install it through MeldaProduction’s free bundle installer, alongside many other free effects from the same developer.

System Requirements

Operating System: Windows 10 or Windows 11, 64-bit
Processor: Any modern multi-core processor; MAutoPitch is highly optimised, using modern processor features, so it runs efficiently on a normal CPU
Memory: 4 GB of RAM minimum, 8 GB or more recommended for larger projects with many tracks and plug-ins
Storage: Around 500 MB of free disk space for the MFreeFXBundle installer and the plug-ins you choose
DAW: Any DAW that supports VST, VST3 or AAX plug-ins on Windows, such as Reaper, FL Studio, Ableton Live, Cubase, Studio One or Pro Tools
Other: A stable internet connection for the download and authorisation, a microphone or a recorded vocal to tune, and speakers or headphones to hear the correction working

These are practical, modern Windows guidelines, not a word-for-word copy of an official specification table. MAutoPitch is optimised for modern processors and runs efficiently, so it will work comfortably on a normal modern Windows PC. Your DAW and your project size matter far more than this plug-in ever will.

How to Download MAutoPitch (Official Method)

The only safe place to download MAutoPitch is the official MeldaProduction website. Do not download it from random file mirrors or “free download” portals, because those copies may be outdated or bundled with unwanted software. The official product page is the source of truth for the current version and for how the free bundle installer works.

Official download link: https://www.meldaproduction.com/MAutoPitch

On the official product page you will see that MAutoPitch is listed as a free effect. You download it through the MFreeFXBundle installer, called MPluginManager, from the MeldaProduction website. The installer contains the whole free bundle, and you choose MAutoPitch during installation. You will also need a free MeldaProduction account to authorise the plug-in, which is done with a licence file inside your DAW, with no dongle and no internet connection required after activation. If a site asks you to pay for MAutoPitch, or offers a “cracked” or “premium” version of it, leave that site and return to the official MeldaProduction page.

Step-by-Step Installation

Open the official MeldaProduction MAutoPitch page linked above in your browser and confirm that MAutoPitch is listed as a free effect. Find the download for the MFreeFXBundle installer, called MPluginManager.
Create a free MeldaProduction account on the official website if you do not already have one. You will need it to authorise the free plug-in later.
Download the MPluginManager installer and save it to your Downloads folder. The installer is the delivery tool for the whole free bundle, so it is larger than a single plug-in installer.
Run the installer by double-clicking the downloaded file. If Windows SmartScreen asks about the program, check that you downloaded it from meldaproduction.com, then allow it to run.
Choose MAutoPitch during installation. The installer lets you pick which plug-ins to install, so tick MAutoPitch, and only add other free plug-ins if you want them. Install the VST3 version for modern DAWs.
Open your DAW and load MAutoPitch on a vocal track. The plug-in will ask you to authorise it: sign in with your free MeldaProduction account, or use the licence file as directed, to unlock the free plug-in.
Rescan your plug-ins if needed and check that MAutoPitch opens and its pitch display moves when the vocal plays, which confirms the installation and authorisation worked.

Tip: Install only MAutoPitch on your first run, even though the installer offers the whole free bundle. A short plug-in list is easier to learn than a long one. Once MAutoPitch is working, you can run the installer again later and add other free MeldaProduction plug-ins one at a time.

First-Use Walkthrough: Natural Tuning, Then Formant Shifting

The fastest way to learn MAutoPitch is to hear its two most useful jobs on the same vocal. Start with natural tuning. Load MAutoPitch on a vocal track, open the plug-in, and set the key and scale to match your song. Set the correction speed to a moderate value and the depth to full, then play the track and listen. The vocal should sound slightly more in tune, but still human, with its natural vibrato intact. Watch the pitch display to see which notes are being pulled and by how much. If a note sounds wrong, check your key and scale first, because a wrong scale makes correction sound worse than no correction at all.

Next, try the hard-tuned sound. Turn the correction speed up to its fastest setting and listen again. Notes should now snap instantly to the scale, giving the stepped, robotic character of modern pop tuning. The same plug-in, the same vocal, a different speed: slow correction sounds natural, fast correction sounds robotic, and the speed control is what moves between them.

Then try the formant shifter, which is MAutoPitch’s most interesting extra. With the tuning set back to a natural speed, slowly move the formant control up and down while the vocal plays. The pitch stays the same, but the character of the voice changes: one way it sounds deeper and darker, the other way brighter and thinner. Formant shifting is also what keeps large pitch shifts sounding natural, because it preserves the vocal’s character when the pitch moves a long way. Try shifting a vocal down by a few semitones with the formant adjusted to match, and compare it with the same shift and no formant correction. The difference is the reason formant shifting is usually found only in paid tuners, and MAutoPitch gives it to you free.

Is MAutoPitch Free?

Yes. MAutoPitch is a free effect from MeldaProduction, free to download and use, for personal and commercial projects, with no trial period, no watermark and no payment for the core plug-in. It is part of the MFreeFXBundle, which is MeldaProduction’s free bundle, and it stays usable after installation and authorisation.

That does not mean everything MeldaProduction makes is free. The company also sells paid bundles and individual plug-ins, and buying the larger bundles unlocks additional features in some products. MAutoPitch itself, however, is free, and you should never pay for it. The only thing it asks for is a free MeldaProduction account to authorise it, with a licence file and no dongle, and no internet connection needed after activation. If a site tries to sell you MAutoPitch, or offers a “cracked” version, it is not the official product, and you should return to the MeldaProduction website.

Frequently Asked Questions

Is MAutoPitch safe to download?
Yes, as long as you download it from the official MeldaProduction website linked in this guide and install it through the official MPluginManager installer. Avoid third-party download sites that bundle installers or offer the plug-in without authorisation, because those are not the official distribution.

Why do I need a MeldaProduction account?
Because MeldaProduction authorises its plug-ins, including the free ones, with a licence file tied to a free account. You create the account once, authorise inside your DAW, and no dongle or internet connection is required afterwards.

Do I have to install the whole MFreeFXBundle?
No. The installer lets you choose which plug-ins to install, so you can install only MAutoPitch. You can run the installer again later to add other free plug-ins if you want them.

What is formant shifting?
Formant shifting changes the character of a voice without changing its pitch. It makes a voice sound deeper or brighter, and it keeps large pitch shifts sounding natural by preserving the vocal’s character.

Does MAutoPitch work in my DAW?
In most cases, yes. MAutoPitch is available as VST, VST3, AU and AAX, in 64-bit only, and it loads in major DAWs such as Reaper, FL Studio, Ableton Live, Cubase, Studio One and Pro Tools. After installing, rescan your plug-ins if it does not appear at once.

Do I need a powerful PC to run MAutoPitch?
No. MAutoPitch is highly optimised for modern processors, and it will run comfortably on a normal modern Windows PC, even with several instances open at once.

Conclusion

MAutoPitch is one of the best free vocal tools on Windows, because it does the main job, automatic pitch correction, simply and well, and then adds formant shifting, stereo expansion and a safety limiter that you would normally pay for. Its free price, honest authorisation and place inside the MFreeFXBundle make it an easy recommendation for any singer or producer.

Download it only from the official MeldaProduction website, install it through the MPluginManager installer, authorise it with your free account, and start with natural tuning. Once you hear how cleanly it corrects a vocal, and what the formant shifter does to its character, MAutoPitch is likely to become the first vocal plug-in you reach for in every session.
