Try this... it worked for me.
Hello Mary.
I have a small room for recording and my computer sits
on a foldup table. In desperation I covered the computer
with a box slightly larger than the tower itself during
a vocal recording. It worked! But there was the risk of
the unit overheating, so I had a friend of mine design
a box with a plexiglas window and a venting system that
works nicely. Another possibility is to use a cabinet or
armoire to locate the unit, or if your room has a closet;
even better- just locate the unit inside the closet with
extended cables for your peripherals, ie keyboard, monitor, etc. It really doesn't take much. Good luck with it.
