while i in no way disagree, i would like to say that "free" low end treatments have thus far eluded my finding them, save for an occasional used mattress or other nasties. and i do fully agree with doing a given task the "right" way, but sometimes, like in my HOME studio, i find compromise (especially of the financial type) to be a pretty much common theme.
to further my argument, i would like to briefly describe acoustic treatments in my modest studio. it is far from pro level, and cost exponentially less to "build". my control "room" (which is adjacent to my instrument room and neither fully separated or isolated) is controlled by only six pieces of 2x4'x2" 703 glass, six pieces of 2x4'x2" wedge aurelex, remnant carpet (on the floor, lol), and a few heavy comforters. ghetto? of course. is it perfect? far from it. but it is a HUGE improvement over PAINTED DRYWALL. the 'glass alone was nearly $100, and as a hand-to-mouther, i had to cut bux elsewhere to afford it.
in the spirit of "free" in the original post, the foam might be perfectly usable, but with obvious limitations, which are well documented on the interwebs. i suppose that i implied that the free foam would "fix" his room by posting "it will work". it wont do that, and for the same reason a thin summer sleeping bag isnt enough to sleep comfortably in a tent in 30 degree weather. but over NOTHING, it is a marked improvement.
so, question444, you should throw it back in the trash. and build a "real" studio. anything less is a waste of time, and completely unusable for audio recording, even within the confines of your home. maybe you could lease a nice room?
isnt there a forum for poor non-professional home recording enthusiasts like myself?
