Re: arsclist Optical Reading System for Wax Cylinders

[David Ackerman <dackerm@xxxxxxxxxxxxxxx>]

Back in January David Julian Gray posted a url [on the audio preservation
list] for a process that uses a laser to map the grove information in the
digital domain as topographical data, and then convert that into sound
minus the noise.  That was in the context of a thread about the ELPrecord
player but I think the site showed the application in use on cylinders.

the url he gave was http://home5.swipnet.se/~w-56154/phono/petrov.html
which seems to have moved to the following:
