Since it seems to be fashionable to resurrect dead threads, thought I might as well put up a current link to the Harman spreadsheet being used -
https://www.harman.com/room-mode-calculator (too simple, right?!?!)
BTW, this is more of a "quick and dirty" approach that can help SOME of the problems in a room; NOT to be confused with the herculean efforts by Stuart (AKA Soundman2020) to show us all the REAL way to do a MUCH MORE ACCURATE job, using REW and an inexpensive (but special, and necessary) mic -

I'm getting close to taking advantage of Stuart's generosity myself; about a month ago my "production" computer took a massive dump, so far I've not been able to resurrect ANY of my info on its boot drive, even with external interface adapters to turn it into a USB drive. The OTHER drive, a 10krpm WD, responds OK and I can get at any and all files on it - the boot drive spins up but nothing else - it's now a project for a crappy day LATER
And yes, I WAS a bad boy; did NOT keep up with backups, couldn't happen to ME, right??
Anyway, that little "glitch" pushed me to decide to replace that ONE computer with two - one already here, a Win7(64bit) laptop, to be used for networking/portable sound, including REW and a newer measurement mic - opted for the Dayton emm-6; good reviews (incl' Stuart's list) and reasonable price ($68 usd @ amazon) - it'll get used with a Focusrite 6i6, just now ordered, and that interface will likely spend MOST of its time with my eldest grandson (the one EVERYBODY wishes they had :=) - he's 19, already makes me look like I shoulda sold at least a dozen of my guitars and at least a few of my keyboards...
My new main system is a Dell, originally bought from Costco - not a complete screamer, but core i7/3.6 gHz, Win 10 Pro; now with 32 gb ram, added firewire card, the original 1 tb drive will get relegated to storage and a pair of 1 tb SSD's added for recording/rendering. It has a separate nvidia graphics card with 4 gigs ram, both DP and HDMI ports (both going to their respective 28" Samsung UHD monitors, and the MB mounted HDMI is going to a third, 22" monitor for a "3 piece desktop" - all 3 monitors will get mounted to a 4 monitor VESA rack that clamps to rear center of the desk, sitting high enough for a hardware mixer NOT to block them, and rearward enough from a pair of my original K-Rok passive monitors - those worked really well with a Yamaha dual 8" powered sub in this room several years ago...
In addition to the Focusrite for me and "super kid", I also ordered 2 new MOTU interfaces, the 24Ai and the 8pre-es - these will give a total of 24 balanced line ins, 8 mic/line pre's and 10 analog outs, ignoring any ADAT stuff.(all on the BACK panel where they belong) - Motu's newer line have the "AVB" bus, basically gigabit Ethernet for musicians - latency around a couple milliseconds, bunch more whistles and bells, check it out on motu's site so you don't hafta skim thru a dozen MORE pages here :=)
Now, the NOT quite so cool part - for the next couple YEARS, all this cool stuff (and more) needs to get crammed into a spare bedroom, while I figure out how I'm gonna do (and pay for) adding a 12'x48' addition onto my shop, tearing out a couple walls, building an outer frame(s) so my (finally, after 3 decades) old studio can go from a total of 432 square feet, to 1152 square feet, with room for ALL my toys (some of which were bought over 10 years ago, and are still in their boxes - and no, I have NOT yet slashed my wrists, sometimes anticipation just hasta be enough
)
The "sorta" good news - that spare bedroom, altho small, isn't a TOTAL disaster (or won't be, when I move 1 desk and 3 HUGE bookshelves out of it) - I've attached a basic axial mode shot (my 20 yr old roomtune still works, for what it is)

- also, there's a 4.5'wide closet in the CENTER of what will be the back wall (behind mix position) that will likely get a pair of sliding rockwool "doors", open to get at stuff and closed to make noise :=)
This project is also turning into the kick in the ass I've needed to get around to tossing a bunch of antiquated crap (no, not me I hope) that I've hung onto for 'way too long - hoarders and small houses are Dante's version of Hell (Abandon all hope, ye who enter here - )
Gotta go, more crap to ditch; I hope everyone's well... Steve
