1 of 2: Ever wondered where Autotune came from?



2 of 2: auto... what?




How does one invent Auto-Tune?
By analyzing seismic data while looking for oil, of course! :o)

That's Hildebrand's previous job: "Oil companies would detonate charges in the ground or in the water, and then they have sensors analyze the reflections to spot the oil," he explains.

That technology was bought by American oil giant Halliburton in 1995 and it's helped internal production in the U.S. soar from 30 to 60 percent, netting the company about $1 billion a year.

"It uses the same science of digital signal processing," says Hildebrand, a long time musician who then applied that science to singing. 

It took him just a month to create it. "Before Auto-Tune, studios would do pitch correction by having the singer repeat a phrase over and over and over.

They would do 100 takes and then patch them together to make one piece of music that sounded in tune."  Auto-Tune does all that at the push of a button.
