Written by Jack Lloyd

Last Updated: October 25, 2022 Tested

This wikiHow teaches you how to apply an auto-tune effect to vocals in Audacity. You'll use a free plug-in called "GSnap" to do so. Contrary to popular belief, GSnap is available for both Windows and Mac computers, though installing it can be a tricky process.

Things You Should Know

Install GSnap on your computer and Enable it in Audacity.
Import or record your vocals in Audacity. Highlight the vocals, click Effect, and choose the GSnap option.
Select your key and play around with the different options by turning the knobs. Preview your settings to ensure you like them, and then hit Apply to save them.

Installing GSnap on Windows

1
Download the GSnap plugin. Go to https://www.gvst.co.uk/gsnap.htm in a web browser, then click the Download GSnap (for 32-bit VST hosts) link near the bottom of the page. The GSnap plugin will download in a ZIP folder.
- The 64-bit version has a bug which prevents GSnap from showing up in the Effects menu.
2
Extract the GSnap folder. Go to the downloaded ZIP folder, then do the following:
- Double-click the ZIP folder to open it.
- Click the Extract tab at the top of the window.
- Click Extract all

Navigate to the Audacity "Plug-Ins" folder. To do so:
- Double-click the "Program Files (x86)" folder.

- Double-click the "Plug-Ins" folder.
7
Paste in the GSnap files. Click anywhere in the "Plug-Ins" folder, then press Ctrl+V. You should see both of the GSnap files that you copied appear in the "Plug-Ins" folder. Now that you've added the GSnap plug-in to Audacity, you'll need to enable GSnap.

Click the Go menu item. You'll find it at the top of the screen. A drop-down menu will appear.
- If you don't see Go at the top of your Mac's screen, click the desktop or open a new Finder window.

Enabling GSnap in Audacity

1
Open Audacity. Its app icon resembles an orange soundwave surrounded by blue headphones. Audacity's track editor view will open in a new window.
2
Click Effect. This tab is at the top of the Audacity window. Clicking it prompts a drop-down menu.
- On a Mac, Effect is a menu item at the top of the screen.
3
Click "Add / Remove Plug-ins…". You'll find this option at the top of the Effect drop-down menu. Clicking it opens a new window.
- You may have to scroll up to find this option.
4
Scroll down and click "GSnap". It's in the "G" section of the window.
5
Click Enable. This button is below the list of available plug-ins. Doing so will switch GSnap's status from "New" to "Enabled".
6
Click OK. It's at the bottom of the window. Clicking it will confirm your changes and close the window.
7
Make sure that GSnap was installed. Click the Effect tab, then scroll down until you see GSnap near the bottom of the menu. If you see GSnap, you're all set to proceed with auto-tuning your vocals in Audacity.
- If you don't see GSnap here, you most likely installed the 64-bit version of GSnap on a Windows computer. You'll have to delete the GSnap file from the Audacity "Plug-Ins" folder and re-download the 32-bit version of GSnap.

Auto-Tuning Your Vocals

1
Import your vocals. Click File, select Import, click Audio..., and double-click the audio file that you want to auto-tune.
- If you haven't yet recorded your vocals, you'll need to record them before proceeding. This may include attaching a USB microphone to your computer.
2
Select your vocals. Click and drag your mouse across the section of the vocals that you want to auto-tune.
- You can select everything in Audacity by pressing Ctrl+A.
3
Click Effect. The drop-down menu will appear.
4
Click "GSnap…". It's near the bottom of the Effect drop-down menu. The GSnap window will open.
- You may have to scroll down at the bottom of the drop-down menu in order to find the GSnap... option.
5
Select a key. Click the SELECT A SCALE... button at the top of the window, select your song's key (e.g., A), select Major or Minor, and click OK
6
Set the knobs to to auto-tune levels. Though you can play with these knobs as much as you want to get a unique sound, use the following settings to get the "classic" autotune sound:
- MIN FREQ: 80 hz
- MAX FREQ: 2000 hz
- GATE: -40 db
- SPEED: Between 1 (choppy vocals) and 10 (smoother vocals)
- THRESHOLD: 100 cents
- AMOUNT: 100%
- ATTACK: 1 ms
- RELEASE: 61 ms
7
Preview your settings. Click the green "Play"
button in the lower-left side of the window, then listen to the vocals.
8
Make any necessary adjustments. The two main things to monitor are the "AMOUNT" value and the "SPEED" value:
- AMOUNT - 100 percent results in the largest amount of auto-tuning, so lower this value if there's too much autotune.
- SPEED - A low speed results in choppier, T-Pain-esque vocals, whereas a higher number will result in smoother vocals.
- You can also remove the sharps and flats by clicking the green circles on the black keys that are on the left side of the window.
9
Click Apply. It's in the bottom-right corner of the window. Doing so will apply the selected settings to your track.
10
Customize your auto-tune. Keep playing with the settings to find the sound you want, but keep in mind the following:
- Larger "ATTACK" and "RELEASE" times make your voice sound more natural.
- Adding vibrato can make you sound more natural.
- The lower the "THRESHOLD" value, the more robotic you'll sound.
- The farther off-key you are on the recording, the more "auto-tuned" your voice will sound when you're done.
11
Save your project as a music file. You can export the track as its own song by clicking File, clicking Export Audio..., entering a name and save location, and clicking Save.
- If prompted to add tags (e.g., the artist name), you can add them or skip the process entirely.

Community Q&A

Question

"Export Files" doesn't come up. What should I do?

Community Answer

Find "Export All". If this doesn't work, try to open the zip file by double clicking it, selecting the files and copying them. If you cannot open it, try installing a zip extractor program like 7-zip.
Question

I did all the steps in part 1 but no window asking me to register appeared, and I can't seem to access Gsnap. Any ideas?

Community Answer

You may need to go to Effect | Add / Remove Plug-ins first. When you're in there you can find it (to enable it) by checking "New" or "Disabled" with the filter on the top right.
Question

What should I do if Norton 360 says that the 64-bit version of Audacity is infected?

Community Answer

This is usually a false positive. The 64-bit version of Audacity is completely safe. You can try other antivirus software to be sure.

Warnings

Given that GSnap is a free plug-in for a free program, it's neither perfect nor anywhere close to professional-grade auto-tuning software.
