Have you heard about this Digital Needle Project? Eggheads have
figured out how to program computers to "read" scans of vinyl
records to play the music, in essence, creating a digital copy of
the records. The program can discern the music from the bumps in
the grooves.
From the project: "Once the image was ready, writing the decoder
was very simple. All it did was rotate a "needle" around a given
center at some predefined angular velocity, attempting to keep
track of the groove the needle was initially positioned on. The
offsets (dr) between this track and the basic radial were bunched
into a sequence of samples. These were later converted into wav
files (see the project at Digital Needle - A Virtual
Gramophone).
I have scanned a record of The Police's single, "Wrapped Around
Your Finger." To solve this puzzle, you must be the needle. Let's
see if you can read the grooves and make the music play.
