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.)

Thanks for such an interesting tutorial. Adobe Audition is another great audio editing tool, although its cost is pricey, whilst the Audacity software is free. I suppose in the studio they use even more advanced equipment to cut gold records these days. Yet its good to know some of us can still tell the difference, hmm? :D

Great tutorial, Microsoft Man! I knew Audacity could add a lot of effects, but not auto-tune. I'll now be using this to annoy some of my friends :D

Nah, jokes. It's interesting to know that a free program can do so much!

As also, did not know you could auto-tune with Audacity, cheers!

Microsoft Man, this blog entry alone has over 23,000 viewers since you posted it. Whatever happened to you? :)

I'm still around, Mike. Life has gotten busy for me over the past year. I haven't had a lot of time to write anything new.
