the ceiling is flat and the tiles are marble i think not 100% sure.
what would you look for in a good recording room? the room ive been recording in is a bit dead so im trying to find a good place to record.
what do you think of car garages? we have a 3 car garage with concrete floor and rafters not ceiling. obviously the dimensions are about 3 cars wide and 1 car long. pretty much rectangular and the garage doors are made of wood.
The combination of a really hard, flat floor and a flat ceiling combined with a bunch of parallel walls with no low or high frequency absorption is less than ideal (in fact it could be an acoustic nightmare), but it could still turn out pretty well.
Is there any furniture in the room?
If there is a couch or couch's or anything like that you can use, put them against the wall(s) at the far end(s) of the room. That will help both with tightening up the low end a little bit and also absorb some high end.
you're going to want to put a rug under the drums. You'll obviously need that so that the drums don't slide around, but it will also help absorb some early reflections.
If you can find a thickish blanket (a moving blanket would be perfect)and figure out a way to get that above the drums it will help with the early reflections also. I don't know how you would do it, but you might try suspending it over 2 shelves or using a large amount of tacks and tack it to the ceiling.
Try putting the drums close to the middle of the room.
your garage would probably be about as good the room with the marble floor. The problem with garage's is there is almost always tools and other stuff that can cause irritating rattles and crap. You also probably won't have things like furniture that you can use as a little bit of room treatment. The rafters would probably have a diffusion type affect which would be good though.
Both rooms have their issues, so try them both and see which one you like more.
