Check out the recording studio part of this forum - you may find some answers there.
I was sick of stuffing my wife (who is my singer) into the closet and had to find alternate methods. I'm not poor and could afford many auralex booths if I wanted but - as we are industrial musicians, the need to create and have a mood changed our minds.
Here is what we did:
1. Bought some foam that you put on top of mattresses at walmart for about $20 or $30 dollars. We covered it in fake blood stains and stuff and covered the bath tub.
2. found an old wooden stool and put that on top of the foam.
3. Bought a 4 x 8 piece of plywood about 1" thick (about $20), cut it to be the same size as the walls around the bath tub, attached a dim interrogators light, and covered it with foam and fake blood stains.
4. Found some old 2 x 4's at a scrap pile and cut them down to size (to hold up the plywood. Nailed some fake ears and hands and stuff to the 2 x 4's.
5. We put some old comforters (that we got from a hotel doing renovations - nice and thick!!) and nailed them to the top of the ply wood so they would hang down all four sides and dampen sound.
6. Success!!
We now have a vocal booth that helps create a mood for our music, I no longer have to feed my wife under the door and we can take it down in a hurry (though leaving it up when unwanted neighbors come by can be priceless!!!)
Just an idea. I'v seen people who would record vocals in the back of their van, in sheds with blankes up everywhere (also served as a practice studio), and storage crates that they ship motorcycles in (with blankets everywhere) that they put in their garage.
If your looking for something more professional looking, think modular. You can buy panels of wood, plastic, etc. - throw on some hinges (so you can fold and unfold the panels, and really doctor them up to look nice. You could include cable runs, lights, a stand for lyrics - hell, just have fun. I think this will help you for better recordings too!! Knowing that you created what is being sold for hundreds of dollars comercially and knowing that yours is probably better will make you comfortable when it counts the most.
Anyway- my .02 rubles worth
