I am currently in the process of setting up a home studio. My computer setup is in my bedroom, which is almost where I am limited to recording, one problem with that is that the fan on my computer tower is not loud, but it isn't silent. I am afraid it would definately come through with vocals on a condenser mic, or with guitar through a sm57. I have two options, moving the computer desk/setup in this long closet, or making that closet the iso room/room where the mic'ing goes on. I think putting the miked stuff in there would be better, as I could line the walls with absorbtion of some kind, and close the door, and the mic wouldn't pick up the sound of the computer fan etc. ( i'll be recording with headphones to avoid monitor noise in the mic). Is this a decent idea since i'm pretty limited to one room? What could I start using to cheaply insulate the closet a bit, or abosrb a little sound. It will just be for recording vocals, and guitar cabs. Thanks for any help.
