For anyone interested, there are free
trials of the software that I use:
izotope rx11 elements.
You need a 'host' to run them as these are plugins - AU, VST3, AAX etc.
RX11 Declicker starting point:
Broadband mode, random. Sensitivity, 2.7. This works for almost all of my recordings.
After declicking, I don't feel I need any more processing at all, and these are all pretty worn LPs from the 60, 70, and 80ies.
It's so nice to rediscover my album collection after all these years and listen to them without the clicks.
(Btw, I did a test with one 'before' file, and one 'after' declicking process, flipped the phase on one, and the result was total isolation of what had changed; the clicks without the music - it's like magic.)
