So do you guys agree it is background noise?
Sounds like background noise to me also. It's probably your computer.
No allow meI'll quote myself..
..Also, if you're recording music, most, if not all, the background noise will be masked by the music. Unless you are doing extremely quiet music or spoken word, you shouldn't worry too much about it. I have a clunky air conditioner in my office that makes a lot of noise and sometimes I forget to turn it off. You can't hear it in the final mix.
