Jim, I don't know if you can watch Youtube, but here's a short clip on
the manual repair process.
So far I've not bothered with YouTube TBH.
However the problem I'm interested in is any algorithm for *finding* (and
listing the positions of) clicks and ticks. The repair is the easy part,
although I'd always do that manually so I can the waveform before and
after. Sometimes a careless repair is worse that the original. :-)
FWIW I've spent many happy hours recently doing just this. Like you I
suspect I trust only my ear as the final arbiter of a click and auto
click removers not at all.
Initially I tried overwriting, actually with EZpatch rather than Repair,
but about half the time that just turned a click into a thud. So I just
redrew the damaged bits manually.
I found you get to recognise the shapes that need repair and on a couple
of really noisy records I didn't bother listening, just scrolled through
looking for the shapes - fortunately just a couple of records. I found a
feature of Audacity is that if you scroll forward at too much zoom it
keeps on scrolling for an indeterminate distance, you need to be 3 zooms
out from seeing the individual points (or sometimes 4, depending).
But it sure is a labour of love, I haven't spent quite so long in
proportion as you but then my standards may be lower.
Still I've resurrected stuff I haven't played for decades, recordings of
Menuhin, David Munrow and my ancient trad jazz (mono, some 10" - yes 33
1/3 vinyl). Brilliant.
