I recently recorded a concert about 20 rows from the left stage monitor, not between the monitors (stage right / stage left). Anyway a womwen one row in front of me about 5 seats down to the left clapped just about all the songs never ending. If I put earbuds in I can distictly hear the clapping in my left bud but if I remove and only use the right side it all but is eliminated.
My question is since there is not much true stereo separation due to my location is there a way I can run the recording through something like "Audacity" and make the left side run with the left channel?
Before making a mono file out of the right side channel without the clapping I'd try one of the methods mentioned above like de-click, de-pop or one of the noise reduction schemes that targets cleaning up a vinyl recording.
If that doesn't work and you want to pursue the dual mono approach all you have to do is import the stereo file into your editor, split the file into 2 mono files, delete the left one (the one with the clapper), duplicate the right one and hard pan each mono file right and left.
I had to do this recently at a bluegrass show where I only had a fixed 90 degree mount but had to run up close and way off to the side. My left mic was pointed at the crowd and they were really boisterous so I just used the right mic that was pointed right at the stack using the method I described above.
