I had to think on this one for a few minutes, but I think I got one. So I've been doing my podcast thing for 110 episodes so far and I just figured out last week that the static wasn't from me having to amplify my microphone so that people could hear me, but from the combination of that and having a fan run behind me. So now I just have to not run the fan and the recording sounds much cleaner. Live and learn.

I record in my kitchen and I have to wait for the refrigerator/dishwasher/heat is all not running to get a clear sound. I hear you there!!

Great answer and so happy you found what was causing your noise
