Hey PICers, This is rather off-topic but ... I just was asked the question pasted below. Does anybody know how those old 'on wire' audio recordings were done and what sort of pick-up head you'd need to extract the signal? (We're talking circa 1920's.) I guess, you could use a 16c73 or sim to digitise them. BUT magnetic tapes have to be frequency compensated before palyback, I seem to recall from long ago. If wire recordings need to be processed similarly you'd probably do that before the digitising stage to keep the processing simple, I guess? Need to think about a drive unit of some sort for the wire spools as well - wonder what sort of speed you'd be looking at? Any tips appreciated - PJH > I have just received an interesting note indicating: > > > are 'hundreds' of recordings of bird > > songs/calls that her husband made back in the early days of field > > recording. > > The recordings are on wire.
