Looks like I’m not very good at this then, like everything else, you’ve got to like doing it to make a good job of it, and a I hate editing.
I don't know Reaper, but it seems like you're possibly using the wrong 'edit' command. In my editor when I 'delete' it just removes it and automatically realigns the audio. Of course, if you get it wrong you simply 'undo' and try again.
In this case I'd highlight the offending peak - often just a few milliseconds - then reduce the level on the highlighted portion, 'commit' (or whatever 'do it term you prefer) and then go on my way.
Just guessing so apologies, but are you possibly using a 'copy and paste' technique?
As for editing, I get enormous satisfaction from taking rough, fluff-ridden, snuffle-heavy audio and making it into something where 'you can't hear the join'. But then I have been doing it for over 45 years and the relief not to be rocking tape and cutting the stuff is huge! :lol:
