Adobe semaphore code cracked by Tennessee high school teacher

Sal Pizzaro:

Waters discovered the project, San Jose Semaphore, last summer while he was looking up something about Thomas Pynchon’s 1966 novel, “The Crying of Lot 49.” The text of that work was the code originally programmed by New York-based artist Ben Rubin in 2006. Seeing there was a new message, Waters began trying to decipher it while watching and writing down the sequences online from Tennessee.

He discovered a pattern that led him to believe it could represent a space — or a silence — in an audio file, and when he graphed the results it looked like an audio wave. He dismissed that as being too difficult but came back to it and eventually ran his results into a program that would convert his numbers to audio. The first results came back sounding like chipmunks squeaking.
