Me too.
It's hard to know exactly what you're achieving at the start, because you may be improving things at one frequency at the expense of another. Bass seems to be notoriously difficult to tame and get balanced right, because those low frequencies can cut through so many materials. So, for instance, you could easily try too hard (and with not quite the right materials) to get the bass under control and end up deadening a bunch of the upper ranges.
I don't really know much (if anything) more than you do, but I do know that my room (an untreated home attic ) has some obvious pitfalls and I'm interested to learn enough to do a reasonable job with it. I have a friend who has a working studio, which has been done but not perfectly, and which is about to be redone. So we're hoping to combine resources and buy some of the materials together and make up batches of panels, or whatever it takes. It will be interesting to see what happens. Our rooms are different, and he's probably aiming for a higher standard than me. I'd also like to have some of my solutions moveable rather than permanently fixed, as the room gets used for other things too.
Here's some files that you can try out (and others) for anybody else interested
Grab the LFSineTones file to test Low Frequencies . Mike Senior's book is a good read too. Worth listening to the file on headphones first, just to convince yourself that it really is level and even, because it probably won't sound that way once the sound gets to bounce round the room a bit.
Good luck with your research, and keep us posted with how it goes, and if you find any interesting information too!
