... Anyway, I've measured an RT60 of something like 2 seconds in the
room, although it seems to be very flat with frequency, rather than the
normally sloping response. With the demo version I can't save a file, so
can't post one, and I'm reluctant to buy the software unless I actually
find it works. I'll make some more measurements and see if I can
understand what's happening.

Don't know the software, but ... you would only get that
sort of RT in a domestic sized room by having virtually all hard surfaces.
That might suit you, but it would be very unusual and most people would
say
it sounded too echoey. I would expect around 0.35 s - 0.5 s depending on
whether you have soft carpet curtains etc, or hard floor, rugs and blinds.
That's in the mid frequency range. At high frequencies it will probably
droop a bit, and at low frequencies it will probably go up to an extent
depending on the room structure.

Anyway if you're using the room to listen to music for enjoyment, the main
question is, does it sound nice. Not like a broadcasting or recording
organisation where rooms should be reasonably standardised. It would be
impossible to judge the balance of the material in a room with a very long
RT for its size but if the sound turns you on, what's the problem?

Yes, the room is hard, having a wooden floor covered in the central
listening area with a 3m dia. long-haired sheepskin rug. Furniture is
leather, and "minimalist". The room has always been difficult as it is
highly asymetrical, but since covering the walls behind the 'speakers with
rockwool, and building a bass-trap for the one difficult corner, it has
sounded very decent indeed. It is also part of a large open-plan layout, so
the room visually isn't huge, but acoustically, is over 12 metres long by 6
wide but only 2.4 high. Neverthless, I enjoy listening in it, but wonder
how it could be better.
