Graillon 2 for PC: How to Download & Install on Windows

Introduction

Auto-Tune style pitch correction used to be expensive, locked behind professional software that cost hundreds of dollars. Graillon 2 changed that. It is a real-time pitch shifter and pitch correction plug-in from Auburn Sounds, and its Free Edition gives you the two most important modules, pitch shifting and pitch correction, for nothing. The result is a free autotune-style tool that sounds professional enough for real vocal productions, and it has become one of the most recommended free vocal plug-ins on Windows.

This guide explains what Graillon 2 is, how its pitch correction and pitch shifting work, what your PC needs to run it, and how to download and install it from the official Auburn Sounds website only. You will also get a first-use walkthrough that tunes a vocal naturally and then pushes it into the hard-tuned robotic sound, so you can hear both ends of what the plug-in does. By the end, you should be able to load Graillon 2 in your DAW and tune vocals with confidence.

Graillon 2 is best for singers and producers who want free, real-time pitch correction, for beginners learning how autotune works, and for anyone who wants creative pitch-shifting effects without buying a paid tuner. Because the Free Edition is legitimate, you do not need a cracked copy or an unknown download site. The official website provides it, and the free edition is a real, permanent tool, not a short trial.

What Is Graillon 2?

Graillon 2 is a real-time voice changer, pitch shifter and pitch correction plug-in for Windows, Mac and Linux, made by Auburn Sounds. In simple terms, it is a tool that runs inside your DAW as an effect plug-in, and it changes the pitch of a voice or an instrument while it plays. Its two main modules are Pitch Shifting, which transposes a sound up or down by a set amount, and Pitch Correction, which gently pulls off-key notes towards the nearest note in a chosen scale, the classic autotune effect.

Graillon 2 comes in two editions. The Free Edition includes the pitch shifting and pitch correction modules, which are the two most important parts of the plug-in, and it is free to download and use. The Full Edition, which costs around 29 euros or dollars, adds two more modules: a bitcrusher and a pitch-tracking modulation section, which creates unusual vocal effects by modulating the sound with its own pitch. For most vocal tuning work, the Free Edition is already enough, and that is why this guide focuses on it.

The plug-in works in real time, which means it processes the voice as it is sung or played, with no need to render audio first. That makes it useful both for recording, where a singer can hear the tuned sound in their headphones, and for mixing, where you can adjust the correction while the track plays. It is available in VST, AU, AAX and LV2 formats, so it fits into almost any DAW setup.

Key Features

Free pitch correction: the Free Edition includes the full pitch correction module, so you can tune vocals to a scale in real time without paying anything.
Free pitch shifting: transpose a voice or instrument up or down, for harmonies, octave effects and creative sound design.
Real-time processing: hear the tuned result live, while recording or while the track plays, with no rendering step needed.
Scale and key controls: choose the key and scale of your song, and Graillon 2 corrects notes towards that scale, with a display that shows which notes are being corrected.
Correction speed control: set how fast the tuning pulls notes into place, from gentle, natural correction to the hard, instant snap of the robotic autotune sound.
Full Edition extras available: the paid Full Edition adds a bitcrusher and a pitch-tracking modulation module for more extreme vocal effects.
VST, AU, AAX and LV2 formats: Graillon 2 runs in most major DAWs on Windows, Mac and Linux.
Free Edition, no time limit: the free version is a permanent tool, not a trial, and it stays usable after installation.

System Requirements

Operating System: Windows 10 or Windows 11, 64-bit (32-bit versions are also available for older systems)
Processor: Any modern multi-core processor; real-time pitch processing is moderate work, so a normal CPU handles it easily
Memory: 4 GB of RAM minimum, 8 GB or more recommended for larger projects with many tracks and plug-ins
Storage: Around 50 MB of free disk space for the plug-in
DAW: Any DAW that supports VST 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, 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. Real-time pitch correction needs a little more CPU than a simple effect, but Graillon 2 is efficient, and it will run comfortably on a normal modern Windows PC. If your project already runs smoothly, adding Graillon 2 to a vocal track will not change that.

How to Download Graillon 2 (Official Method)

The only safe place to download Graillon 2 is the official Auburn Sounds 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 site is the source of truth for the current version and for the Free Edition download.

Official download link: https://www.auburnsounds.com

Please note this plainly: the link above is the official Auburn Sounds homepage, because the exact Graillon 2 product page address could not be verified at the time of writing. From the homepage, open the Products section and choose Graillon 2, where you will find the Free Edition download for Windows. Do not use any other site for the download, and do not trust a page that offers a “full free version” of Graillon 2, because the Full Edition is a paid product and only the Free Edition is free.

Step-by-Step Installation

Open the official Auburn Sounds website using the link above, then go to the Products section and open the Graillon 2 page. Look for the Free Edition download.
Download the Windows installer for the Free Edition and save it to your Downloads folder. Choose the 64-bit version for a modern PC and DAW.
Run the installer by double-clicking the downloaded file. If Windows SmartScreen asks about the program, check that you downloaded it from auburnsounds.com, then allow it to run.
Follow the installer prompts to choose the installation folder and the plug-in formats you want. Install the VST3 version for modern DAWs, and add the VST2 version as well if you use an older DAW that needs it.
Note the VST plug-in folder the installer uses, or choose your usual VST folder during setup. Keeping all your plug-ins in one known folder saves trouble later.
Open your DAW and rescan your plug-ins if Graillon 2 does not appear at once, then look for it in your effects list under Auburn Sounds.
Load Graillon 2 on a vocal track and check that the interface opens and the pitch display moves when the vocal plays, which confirms the installation worked.

Tip: Before you tune anything, set the key and scale of your song in Graillon 2 first. Pitch correction only works well when it knows which notes are correct. If you skip this step, the plug-in will guess, and it will pull notes towards the wrong scale, which sounds worse than no correction at all.

First-Use Walkthrough: Natural Tuning, Then the Robotic Sound

The fastest way to learn Graillon 2 is to hear its two extremes on the same vocal. Start with natural tuning. Load Graillon 2 on a vocal track, open the plug-in, and set the key and scale to match your song. Turn on the Correction module and set the correction speed to a slow, gentle value. Play the track and listen: the vocal should sound slightly more in tune, but still human, with its natural vibrato and small pitch movements intact. Watch the display to see which notes are being pulled and by how much. If a note sounds wrong, check that your key and scale are correct before you change anything else.

Next, try the hard-tuned robotic sound that made autotune famous. Turn the correction speed up to its fastest setting, so notes snap instantly to the scale, and listen again. The vocal should now have the stepped, robotic character of modern pop tuning, where every note lands exactly on pitch with no slide between notes. This is the same effect at a different speed: slow correction sounds natural, fast correction sounds robotic, and the speed control is what moves between them.

Finally, try the pitch shifter on its own. Turn off the Correction module, turn on the Pitch Shifting module, and transpose the vocal up by a few semitones, or down by an octave for a deep, dramatic effect. You can use this for harmonies, for doubling a vocal at a different pitch, or for creative sound design on instruments as well as voices. When you find a setting you like, save it as a preset in your DAW so you can recall it on the next song.

Is Graillon 2 Free?

Graillon 2 has a Free Edition, and that is what this guide covers. The Free Edition includes the pitch shifting and pitch correction modules, which are the two most important parts of the plug-in, and it is free to download and use, for personal and commercial projects, with no trial period and no time limit. It stays fully usable after installation.

The Full Edition is a paid product, priced at around 29 euros or dollars, and it adds a bitcrusher and a pitch-tracking modulation module. Those extras are creative tools, not corrections to the free modules: the pitch correction and pitch shifting in the Free Edition are the same as in the Full Edition. You do not need the Full Edition to tune vocals properly, and you should never pay for the Free Edition itself. If a site tries to sell you the Free Edition, or offers the Full Edition for free, it is not the official product, and you should return to the Auburn Sounds website.

One honest note is that Auburn Sounds has also released a newer Graillon 3, so check the official site for the current product line when you visit. Graillon 2 Free Edition remains available, and this guide covers that version as verified. Always read the edition comparison on the official page before you download, so you know exactly which modules your edition includes.

Frequently Asked Questions

Is Graillon 2 safe to download?

How do I get the natural autotune sound?
Set the key and scale of your song, turn on Correction, and use a slow correction speed. The tuning will gently pull notes into place while keeping the vocal’s natural vibrato and expression.

How do I get the robotic autotune sound?
Use the same setup, but set the correction speed to its fastest value. Notes will snap instantly to the scale, giving the stepped, robotic character of modern pop tuning.
