My usb blue yeti (not pro) sounds great, but I was wondering if there was a dac or something I could use to clear up the mud from the audio (it picks up a fan from out the hallway at a low enough gain to hear me as clear as possible. It's just a small amount above the lovest setting.) and clear up the static from the aux pass through. I'm not looking for noise cancellation, because I will turn up the gain to max when not recording so I can hear my parants yell for me to do chores and other things) Thanks in advance.
