Hi guys, wish I would've seen this thread earlier, cause I would've posted. I turned a studio apartment with a bathroom into my studio. I knocked everything out, removed the toilet and sink, and turned the stand up shower into the vocal booth/reamp booth?.
But, I deadened everywhere in the room with duct board w/canvas over it. In the shower though, I made the duct board panels removable, and I occasionally use this on electric guitars. It kinda makes it have that 70's Brian May type of small room verb. But this is application specific.
My advice...save the money on auralex, cause it's not going to help in a tiled room. You will end up spending 500 damn dollars just for absorption material. Instead go to your local air conditioning supply store and buy duct board (sheets of 4x10 cost about 20-25 bucks), cover with canvas, screw into the walls.
The main thing to remember is that although a tiled room may work in some (and I do mean some) instances, for vocals you want the room to be as dead as possible.
Hope this helps..
