I've had success in lifting a few milliseconds from somewhere else in the recording - usually from another chorus, or verse or bar in the piece - and inserting it where the zit was excised. This is only a sometimes solution, though, although it's invisible when it succeeds. Works for both analog and digital splicing, but best done digitally, because with analog you'd be working from a copy. Realistically it should be at 15 or 30 ips, too, to have enough tape to splice!

<snip> When the needle jumps the groove like with a gouge or a big vinyl zit, all bets are off because there is no underlying music to mimick. I try to avoid records in that bad shape but sometimes you get 'em. After years of doing this, I've come to the conclusion that the most natural-sounding solution is just reduce the pop waveform to the level of the accompanying music. <snip>

Hi Tom,
I assume the reference to "Jack" is a reference to Jack Towers.
He will tell you he got the oxide scraping technique from discussions
with the late John RT Davies. I have worked with some of John's tapes,
and I can report his scraping was VERY carefully done. I have also worked
with some of Jack's tapes, and I have to say Jack usually took off too much
oxide, producing an obvious dropout; I had to fix lots of these, using
crossfades, or by careful deletion of part of the audible silence.

Hi Parker:
I'm sorry, I misunderstood what you were describing. Now I understand. That would absolutely work, but what an art form! Wow, I wonder what Jack experimented on to learn the art.

But if you do Jack's method, you're left with the same problem as Terry -- a
microsecond of blank space, which is just as noticeable and annoying as the
click.
By scraping off only the precise moment of the click, you're in effect
creating a high speed fadeout and fade-in. It's audible, but less annoying
than the click itself.
There's an overview of analog and digital de-clicking at http://www.cedaraudio.com/intro/declick_intro.html - but without a description of manually scraping off the oxide.
