Someone explain AUTOTUNE to me?!?!?!?!?

autotune is a device that fixes the pitch in your voice. If you have an iphone ipad or any thing like that there is an app called la di da free that will autotune your voice. It only sounds computerized when the device is constantly trying to fix the voice hence videos you see on youtube. Anyone can get famous because autotune will just fix your voice if ur off pitch. Hope I helped!
