I use ClickRepair extensively - weel worth the $40 IMHO -see this thread: https://forum.audacityteam.org/t/click-pop-removal-clickrepair-software/1933/1
I experimented with Brian’s NoiseRemoval tool for an older LP that I had of even older blues recordings - they were obviously trnascriptions from various 78s and the LP was engineeered before the advent of digital processing. I found NoiseRemoval a little harder to set up than ClickRepair - and I needed different settings for each track - but it did work well.
BTW thanks to everyone for the contributions to this thread. I shall shortly be adding a section in the Manual Tutorial on Transferring Tapes, LPs etc on recording and processing 78’s so the input has been most useful. Any further contributions gratefully received.
