Greetings Fellow Golden Ears,
I have just setup with the help of our illustrious moderator's help
a anon archive of pc programs for audio. There are currently four programs
available. Snell.zip contains a speaker placement program developed by
Snell. It takes room measurements and calculates resonant modes in the room
and give you back a listing of best, good, and better locations for your
speakers. Placement.zip is a similar idea only from Allison and spreadsheet
based. It is a lotus spreadsheet and I personally haven't been too succesful
with it though I haven't tried it with Lotus itself, just quattro and excel.
Boxdesin.zip is another spreadsheet (I have been able to get results on
several spreadsheets with) that does enclosure/frequency response calcs.
It does 2 and 4th order enclosures and is quite nice. Loudsp.zip is also
a design program. It is standalone and does a bit more like crossover
design (2nd order passive). It requires a color monitor. All of these
programs were obtained from Compuserve and are public-domain. You can
get them by anon ftp from csd4.csd.uwm.edu in the high-audio/Software
directory. I hope you find them useful and that we can build a nice
little library.

The Allison speaker placement program works very well and easily on 123 and gives truly useful and audible results. The only glitch I noticed (although I am using a more recent version than what may be available here) is that the intro talks about figuring the distances to the 3 nearest boundaries (front wall, side wall, floor) in feet whereas you actualy enter the data in inches. FYI, I believe the Snell version (like the Sitting Duck version) only believes rooms resonate along L, W and H; it ignores LW, LH, and HW and LWH. I may be mistaken in this but if it is the case then the program is useless. I know the Sitting Duck program only does the 3 dimensional modes for its computation and it is therefore useless. Users more savvy than about spreadsheets have said the Allison program works readily on Excel and Quattro but I cannot speak from experience...
