Making Old Sound Recordings Audible Again
orgelspieler writes "NPR is running a story on a safe way to reproduce sound from ancient phonographs that would otherwise be unplayable. The system, called IRENE, was installed in the Library of Congress last year. It can be used to replay records that are scratched, worn, broken, or just too fragile to play with a needle. It scans the groves optically and processes them into a sound file at speeds approaching real time. IRENE is great at removing pops and skips, but can add some hiss. Researchers are also working on a 3D model that is better at removing hiss."
Can add some hiss to what? To the perfect Hi-Fi quality you are expected to get out of a century old phonograph?
Nuffsaid

Don't know about his cat, but Schroedinger is definitely dead.
No offense to some of the bright high school students and undergrads who comment here...you're appreciated, sometimes for you're youthful naivety, but appreciated nonetheless.
and some guy also tried it years ago with just commercial scanners (http://www.cs.huji.ac.il/~springer/), although the results weren't that great, but at least it's a proof of the concept.
