Harold “Dr. Andy” Hildebrand is credited for inventing auto-tune. Auto-tune is an audio plugin that is used to help correct the off-pitch vocals of a singer. Hildebrand used sound waves for locating oil reserves. Hildebrand discovered that these same sound waves can be used for music too.

One of the first users of vocal effects for auto-tune in entertainment was Cher’s producers. The song used was “Believe” by Cher. In 2005, T-Pain began using auto-tune for vocals in every single song he made. Soon many other artists started using auto-tune. Auto-tune became so overused that many parodies were made.

In the video above, there is an auto-tune parody added to a baby crying, a cat meowing, and Winston Churchill. Many unmusical things on the Internet had been given auto-tune. The report was put together by RocketBoom.

“Weird Al” Yankovic has created a new song called Craigslist. Yankovic imitates Jim Morrison of The Doors throughout the song and he dresses in leather pants and a white shirt in the video. Ray Manzarek of The Doors even helped putting the song together and is playing the keyboard in the background.

Yankovic plans to release this song out of a five song digital download package later this summer. The digital EP is called Internet Leaks. Lyrics are available after the jump just in case you want to sing along with the video.
