I believe that you will have very good results with cork. Too much absorption will make your room sound "dead" and "lifeless". Cork should give just enough absorption to get rid of nasty high frequency reflections. I have found that natural materials work very well and produce a "natural" sound. I am currently using some woven rattan (dried grasses) mats on the walls with very good results. I have wanted to try cork but haven't done so yet.

There are two kinds of cork available in the US. One is a very dark brown and has a coarser texture. It is usually sold in sheets about 1/2" thick. The other kind is light tan and much smoother. It comes in rolls and is about 1/8" thick. Both kinds would probably be useful, but I would probably start with the darker, rougher kind.

I would try to avoid painting the cork. I think it would it would fill up the pores and negate the sonic properties.
