I just ran across this today, thanks Slashdot. It’s a tribute to Carl Sagan of Cosmos fame and was put together by auto-tuning Sagan’s own dialogue. Auto-tuning is a method by which you can change the pitch of an existing sound. It is often used to “fix” mistakes musicians make when recording. More recently, it has been used to create entire new works of art by modifying the pitch of recordings to the point of distortion and “tuning” them to follow a given musical flow. In the end, you end up with something like the following video:
You can download this video, or an MP3 of this from the artists site. I also recommend checking out The Gregory Brothers and all of their auto-tuning goodness.
