Having recently been asked about the restoration and re cutting (on “modern” vinyl) of a 40 year old recording on acetate disc … I replied …
“We’d have to try playing and “cleaning up” the acetate’s audio to asses how much we can rescue, and assuming that result was acceptable, making new vinyls for collectors is no problem at all.
With “really” old records, acetates and even earlier cylinders, the only way to see whether the audio can be recovered sufficiently is to try. It’s a “bit of a slap” potentially sending discs around the world I know, but there’s no other way !”
Here’s a tiny snippet of a 78rpm recording, the audio of which was buried under a million random scratches and surface noise. The “clean up” process can’t of course do everything !!, but it will result in a record, playable on modern equipment, without the need for a special stylus or cartridge and will have “more music than noise” rather than the other way round !!
