Keeping what is common between a stereo track

The best app that I know for removing clicks and pops from records is Brian Davies’ excellent Click Repair’ See this sticky thread: https://forum.audacityteam.org/t/click-pop-removal-clickrepair-software/1933/1

It costs a little, but you do get a 14-day free-trial - so if you only have the one record you should easily get it done within the free-trial period.
