When it comes to dealing with loud applause during a quiet concert, I've tried a number of these suggestions and have found there is really no "easy way" to get rid of them.
So I've been using an extremely labor intensive method in Audition - Auto Heal.
This requires that you select and process each individual hand clap. But I've found it to be extremely effective and virtually unobtrusive on shows I want to preserve for my own future listening pleasure.
As an example, I recently attended the Anders Osborne/Luther Dickinson acoustic show at the MACC here on Maui. There was a guy sitting two seats away who insisted on clapping louder and longer than anybody else. He was so loud that he hurt my ears even through my ear plugs!
Attached is a capture of what the applause looks like in spectral view. Following is a capture of how narrow the auto heal selection can be. For anyone whose DAW does not contain auto heal, what it does is replace the selection with a bit of audio from each side of the selection. I've found that even if the "clap" is occurring during the performer's comments after the song is over, there is still no discernible effect on the comment.
Once again, this is very labor intensive and in the case of that gentleman sitting two seats away - I counted between 40 and 80 claps after each song! However, once the claps are eliminated, it's possible to boost or normalize the remaining audio and not be blown away by applause when listening in headphones.
