I'm getting a really weird buzzing sound from my recording device. It's constant throughout the video. I thought at first it may be the A/C running in the background, but after cutting it off, the annoying noise was still there. I'm not sure if it is the mic doing it, or if it is feedback from the game it's self.

Anyone else ever had this problem? Suggestions to make it go away or just tune it out in the editing process?
