Re: sound proofing a room
You'd need to put insulation in your interior walls. Exterior walls have it, interior don't. Then buy some really thick rubberfoam for your door. That won't completely sound proof it, but it will make a huge difference. They have some kind of foam now, don't know what it's called, they drill out a hole in your wall and fill it up and it hardens into some wierd styrofoam.
Actually, I just realized your on the second floor. I really don't know what you could do there... unless you want to stand on insulation. What kind of floor do you have in your room? You may want to consider some heavy carpet. I have really thick shag carpet in my room, it makes a huge difference when you record.
