It's the strangest thing and I have no idea what's causing it.. It happens with my headset and with my laptop mic. I have upped the mic boost and mic levels to amplify it but it is always there, albeit quieter when the levels are normal.
I've tried turning off skype and any other program that could be tapping into my mic and causing some kind of interference but it's still there.
You can hear it here: http://youtu.be/Po0wjDcwkZE and this is without me saying anything or any actual background noise in the environment around me. I swear my leading theory right now is that Aliens are trying to contact me
Thanks!
