Buzzing with voice peaks - even after noise reduction.
I am working with a 3 minute video and about halfway through the mic started buzzing. No problem I thought, I went through my audio editing progression and used the noise reduction process to get rid of the buzzing. And it worked. But, the buzzing still persists when the voice peaks. I can't seem to get rid of it even by isolating frequencies, and I can't find any information on how to do it online.
Here is the .wav file, you'll start to hear the buzzing around 15 seconds in.
