After Colbert tonight I left the TV on for a bit of South Park, a show whose virtues are mostly ignored by me, thanks to its gratuitous profanity. But what hit me this time is how the voices of the kids are, in the tradition of David Seville and the Chipmunks, obviously sped up.
I grabbed 90+ seconds of audio, then slowed it down. A reduction of 25% sounded about right.
