Insta-Foam for Acoustic Treatment?

[rayc]

Stupid Question on my part but I'll try it anyway:
My ground floor, back of the house recording space has unsealed compo board bookcases lining 1 & 1/2 walls almost to ceiling with a wide range of book heights, lengths & cover types, and book types (hard down to paperback, filling the shelves. (ie: there's no standard space or density etc along the shelf contents)
The remaining 1/2 wall has a mix of hard & semi soft irregular stuff - small bookcases, piano, etc. covering much of it.
Where these aren't, amps, speaker cabs, cables on hooks etc are set out.
A third wall is 2/3rds in height & entire length window with VERY heavy curtaining floor to almost ceiling & a "15inch space" between it & the glass. There's a 2nd, lighter, curtain set, (old band backdrop) rolled up onto the pelmet for extra coverage.
The floor is dense carpet & underlay over a concrete slab.
Outside the big window is a small walkspace then a three step retaining wall with lots of foliage.
The final wall is the one behind the tape players & DAWs broken up with 2 sets of monitor speakers as well as the hard but irregular (inrelation to one another) shapes of power amp, rack, comp monitors, lamps etc.from table height up & stored gear, books & magazines below.
The ceiling is my only really exposed bit of flat reflective surface.
After recording, monitoring & mixing in this room the responses I get from stereos, etc. in various other rooms isn't significant in terms of excesses/deficits in high, mid or low response.
Am I, as I feel, just dead lucky or, as I'm afraid, just cloth eared?
Cheers

Do not move anything in that room!
It's hard to say if you are lucky or you just have a good sense of how to mix in that room. In other words, that is what you are used to.
I think you would be surprised what some good bass trapping will do for you.
Play something back and walk around your room especialy the corners and see how much the sound changes.

I've been using my control room for almost two years without any bass trapping and I've simply gotten used to how to make mixes sound good elsewhere. But yesterday I used the sonar file from the realtraps site and did the test just how they did in the video and it's disgusting how bad my room's response was. There were some huge peaks, and huge valleys. Then I threw up some insulation in the corners and tested again and it flattened everything out so much I couldn't believe it. Except for a huge peak in the 45 hz range, everything was really close to how I'd like it to be once I get real bass traps in.
