What about Acoustical Room Dimensions?
I would like to tell about one (to my opinion) interesting thing, concerning to room acoustics. Being an acoustician, when I have heard somebody (an architect or interior designer), who did presentation about his wonderful stereo, home cinema or recording studio acoustics, I have asked him, why did you take these dimensions of your room? There were many different answers and a simple thought came to my mind, that among all possible stereo positions (for example) for the room there will be a number of such, which have a given value of FR deviations for low frequencies range. Let's call this number as Spread Number. As we have initial room dimensions set, which could be reduced by a little bit (this is always limited by some conditions), than there are many options, where each set will correspond his SN. And it means, that there is set with minimum and maximum SN for these initial room dimensions, deviation limit, kind of LF sources (stereo, for instance), don't you? Evidently, set for maximum correctly to call Acoustical Room Dimensions. What do you think about it?

sure, a recursion process to get to a set of "best" options would be nice. there are several room sizing programs, and some include proper speaker / location specifications as parameters, and iteratively work to identify the best size and locations. and some can work with existing rooms (more common for homes) and propose best locations. what would be really useful (for existing) is an application which can scan the room for response, resonances, etc to feed the processing (like REW for example ).
for new (green field) rooms, then being able to compute the best sizing would be excellent, and perhaps some real world data on proposed structure would add more reliable results. adding in the ability to include baffle / speaker / absorption parameters would also save a lot of time...
my current process of using several spreadsheets, BEM/FEM analysis, etc takes a significant amount of time to get to a good result.
some happy reading on some current thinking on this topic.
