stolen link from my friends website:
A guy from an Israeli university figured out a way to scan records (vinyl) with a flatbed scanner and convert the image data into audio. He explains the process with images & sketched diagrams, and includes a number of sample conversions to listen to.

i did a search and i couldn't find if it was a repost.

Neat!

Based on that premise, if you had a high enough resolution scanner, you could do that with CD's too...

For that to work with CD, the resolution would have to be REALLY high. But that's so awesome. Thanks Eaks.

Despite what you may think....this would not work with CD's as they are digital 0's and 1's or data that are read by a laser, while records were analog and the shapes, depths and grooves are what made the different sounds, notice he said he made a digital needle, basically he made a program that would read the same things as record needle does when placed on a record.

it would work if you had a good enough scanner. those 0's and 1's are pits on the cd, you know. i don't think anyone has a scanner that good just lying around though. ;)

edit: oh yeah, this was on /. a few months ago. he's done some updates since then, though. he improved the soundquality a fair amount.

Data is encoded to a CD in varying size pits, pressed or burned into the substrate. Basically dots and dashes.

You sir, are incorrect. :)

I'm sure Edison's first light bulbs sucked too.

dude, he did this with a crappy consumer scanner (not even big enough to scan the whole record at a time, let alone scan in fine detail), in his spare time, with no prior knowledge of even how records work. the fact that it works at all is incredible. he's also made big improvments over his first attempts. this could be very useful in the future for making more accurate digital masters from old recordings. it just needs some work and better hardware.
