So, there's an irritating background noise, whenever I try to audition for some something and I don't know what it is. I've unplugged the fridge and turned off the air conditioner in my dorm room but it still won't go away. I've heard this sound in numerous auditions from other people as well. However, I don't know if any of those other people ever got roles in anything. I'm guessing that it's some sort of feed back. My technology isn't very good (I'm using a built in microphone, free ear buds that I got on a plane, and GarageBand) but, I've adjusted the mic to a low level and edited out as much as I can but it's still an issue.... Is there a way to solve this problem? And do people who have this problem still have a decent shot at most roles for most projects?
