Auto-Tune Your Voice

Have you ever wanted to auto-tune your voice? If your a person who has listened to popular singers such as T-Pain, you’ve probably heard this effect in action. Surprisingly, this technology was originally created to make minor corrections to a singer’s pitch, which allowed them to sing perfectly tuned tracks. Most people don’t see it that way and assume Auto-Tuning is just “skewing” a person’s voice, making a robotic sounding effect. I have to admit, auto-tuning your voice in order to distort it is quite entertaining. Since I am not a good singer I have no reason to correct my horrible singing voice. That leaves my with entertaining myself by distorting my voice.
Applying an auto-tuning effect to one’s voice isn’t hard or necessarily expensive. Surprisingly, it can be done using absolutely free software. Of course, if you feel you would rather buy a professional software, go right ahead. The cost for professional software can reach higher than $200, so why not try some free alternatives. For starters, you are going to need a sound-editing application. Audacity is an example of a free sound-editing application. I would recommend using Audacity version 1.3 beta or higher. The second thing you need is a free plug-in called Gsnap. Gsnap is a VST plug-in which must be installed into Audacity’s plug-in folder in order for it to function. The address path should be something like, “C:/Program Files/Audacity/Plug-Ins/”. Unfortunately, Audacity doesn’t natively support VST effects so it will require a VST Bridge Plug-in to be installed. After the bridge is installed Audacity should handle any VST effect installed into the plug-ins folder. Finally, the last thing required is a microphone. It doesn’t have to be expensive, a cheap microphone will work just fine.
Here are the steps to begin auto-tuning:
  1. Have Audacity, the VST Bridge Plug-in, and Gsnap installed.
  2. Start Audacity, and make a recording or open up a sound.
  3. Go to the effects menu and select the GVST: Gsnap effect. From there you need to set all the settings to the following values:

    •    Min Frequency: 80 Hz
    •    Max Frequency: 2000 Hz
    •    Gate: –80 dB
    •    Speed: 1
    •    Threshold: 100 cents
    •    Amount: 100%
    •    Attack: 1 or 2 ms
    •    Release: 4 ms
    •    Pitch Blend: 0 cents
    •    Vibrato: 0 cents
    •    Vib Speed: 0 cents
    •    Calibrate: 440 Hz
  4. Press the OK button and allow Audacity to render the effect. (Tip: For a better sounding effect, go to the effects menu and repeat the effect.)

Hey i've got problem with ur tutorial, i do everything like it has to be, but i dont have GSnap in audacity :/ cant find it in effects

Did you install Audacity version 1.3 Beta, the VST Bridge Enabler, and the Gsnap plugin? Did you extract the Gsnap plugin from its .zip folder to the plugins folder in C:/Program Files/Audacity/Plug-Ins ??? If you did all of this, it should work.

Hey there. I did the same thing, and couldn't get it to work.

model:Dell Mini 10
processor: Atom: 1.6 Ghz\
Windows XP Home Premium

Hey, I was wondering if I could edit setting in Wave Pad to sound like Auto Tune??? Is it possible without downloading other programs???

i've downloaded everything,and it doesnt show the GSnap effect :/ help?

For those of you who are having problems getting the Gsnap plugin to show up in the effects menu, try this. Go to Edit->Preferences (or just click ctrl-p) then go to effects and make sure everything is checked then restart Audacity. If that doesn't work, make sure you have the latest version of Audacity installed. I forgot to mention in the post that the Gsnap plugin needs to be extracted from its zip folder (as does the vst bridge enabler if you downloaded the .zip version). Move the .dll files to the program's plugins folder. If you are using a beta the folder directory should be something like C:/Program Files/Audacity 1.3 Beta (Unicode)/Plug-Ins/

Hey Nick! Can you get the Auto Tune Effect on Wave Pad Sound Editor???

Some Guy, yes you can use the auto-tune effect on WavePad Sound Editor as it also supports VST plugins. WavePad actually supports VST plugins by default (so you don't need the VST bridge enabler). When I originally did this post, WavePad wasn't able to correctly display and use the Gsnap plugin. I just installed the latest version of WavePad and the plugin seems to work now. All you have to do is download the Gsnap plugin and extract it somewhere; it doesn't really matter where. Then, open WavePad and go to effects->VST Plugins. A window will come up asking for the location of the VST plugin. Click browse, and go to the folder where you extracted the Gsnap plugin. Click OK, and then make sure that Gsnap is the plugin that is selected in the drop-down list. Press OK, and your free to auto-tune anything.

Thanks! Good to know!

You extract the .zip folder with Windows by right-clicking on the folder and selecting "extract all...". You can also use 7-Zip, WinZip, or WinRAR to extract the .zip folder if your computer doesn't have the option built in. 7-zip is free.

Please note that since Audacity 1.3.8, the VST Bridge Enabler is not required.

The current version of Audacity is 1.3.13 and this includes an open source VST header so the VST Bridge should not be used.

i got everything, but im trying to open the folder for g snap, i dont have win zip anymore, is there another program i can use to open it?

Try downloading 7zip, its free and opens a whole host of other compressed files.
