StarMaker Interactive, the developer behind Auto-Tune Birthday, writes that “Jay-Z may have pronounced Auto-Tune dead”…but hey, Auto-Tune The News has 240 million views, so clearly plenty of people find Auto-Tune’s distinct sound hilarious. That’s the idea, anyway, and it’s the reason why we have this…monstrosity?…on our hands. In this app, Auto-Tune meets perhaps the most unremarkable, aged song in popular culture: “Happy Birthday.” I think that the app’s description sums it up best: “You singing “Happy Birthday” + Auto-Tune + Facebook = The best birthday wall post your friend will get!”

Auto-Tune Birthday is an iPhone app that lets you sing and record yourself singing Happy Birthday, and then auto-tune the resulting song. From there, you can post the recording to Facebook or send it via email. When posting a song to Facebook, the app allows you to add photos, graphics, and a personal message as well as the recording.

The app includes ten “versions” of the Happy Birthday song, including Hip-Hop, Rock, Samba, Synth Pop, and more. Auto-Tune Birthday also ties into Facebook so that it can send you birthday reminders. Check out the results in the video below.

“Facebook users have become accustomed to receiving the somewhat impersonal ‘Happy Birthday’ wall posts on their birthdays,” says Nathan Sedlander, President and Co-Founder of StarMaker Interactive, “Auto-Tune Birthday’s studio-quality Auto-Tune and easy integration with Facebook lets users create fun wall posts that stand out, have a personal touch, and are generally more awesome.”

The app’s developers have experience with harnessing Auto-Tune to hilarious effect: their Auto-Tune Christmas app produced funny versions of Silent Night.

Auto-Birthday is available in the App Store for $0.99.
