hi
not sure if link is ok (abc)http://www.abc.net.au/science/articles/2008/03/28/2202033.htm?site=science&topic=latest
...or if peeps know about this already..sorry..
but they..? resurfaced sound on black carbornate music score sheets into audio??? ....amazing ..can anybody explain this to me......us..

Im not pretending to be an expert on this at all, but is actually quite simple.
The engravings are no different than normal record grooves - they are simply the trace of motion though air. No magic here:-)
Thus they can be scanned using a normal scanner, and converted into sound.
ofcourse you need software to do the math regarding angle, motion and so forth...
The technique are used to restore old cylinders that are to brittle to be played.
It is also possible to remove crackle and clicks using imagesoftware...
all quite interesting....especially if you could get hold of some of the software to do it....

That's fantastic. Everyone's been telling me about this.

As a matter of fact I emailed someone I know who was at Stanford for the presentation and he agreed with me they could have done this over 50 years ago if they would have had the original photoautograph pieces of paper.
Beside the thing your computer generates when editing audio, what else is an optical/visual form of a sound wave? - Right! an optical motion picture film sound track. They could have fairly easilly photographed this phonoautograh paper and turned it into a continuous line of audio squiggles, printed it on some sort of film stock and run it through an optical sountrack pickup head (adjusting for speed etc.) Audio (of some kind) probably inteligible would have been the result.

ofcourse!
I think that it could have been done even earlier.
Optical soundtracks where in use already in the 1920'ties - and was surely developed some time before. I vaguely rememeber that Thomas Edison fiddled around with it.....
strange to think about the fact that the Telefax, Television and computers were all invented before 1900 - just took some time to develop and spread....
