You've done a great job with it John! It's great that you've thought of and added all those little touches. It's a very well thought out user friendly program.
I'm not sure what is the correct place for this, but one feature I'd like to see is waterfall normalisation ie how would the waterfall look if EQ were used to get it perfectly flat.
EQ affects the rates of decay as well as the level, the predicted waterfall on the EQ panel shows how the current measurement would look with EQ applied - there is an example of before and after in the screenshots on the REW page.
Let me put it this way. Let's suppose you want to compare some bass traps with REW and see the impact on waterfall plots. (That is one thing I've been doing). It can be hard to compare when the response is different. If the waterfalls and decay plots could be normalised, then comparison is easier.
not to mention the mouse-wheel scrolling option to zoom in on out-of scene measurement areas.
I do anlaysis from 20Hz to 16KHz, and the normal window gives me to 200Hz. BUT if you scroll into the end you find you can open the entire spectrum.... THIS IS AWESOME AND MUST BE TOLD !
(I just discovered by fiddling).
Incredible Design, John, thanx....
MAN! That is so cool. Sure glad you posted this. I have two ECM8000 and two EMM6. I use a Blue Icicle or MXL Mic Mate to connect to USB.
When I read this, I had to experiment a little. Neither model have had the "HTS Official Calibration Curve" run. I used a pair of Koss R80 Headphones to play with. Placing the mic's between the cushions and gently holding them in place, I ran a number of 30-20,000 curves. The response between all 4 mic's was almost identical from 30 to 3,000hz. After that there were variations , but averaging the high end showed they were not too far off. Minor variations can show up just by how you hold the cushions and the exact placement of mic each time a curve is run. I'm going to do some free field speaker test's when time permits, but it was sooo neat I can't get over it. All my thanks to everyone who had anything to do with developing the REW.
I'm 70 yrs old and it makes me feel like a youngster when I was a Lab Tech at American Microphone Co.
How can I link your program to my Blog, bro ?? Or is there a Facebook link ? There must be thousands out there who would appreciate this work of art...
hey, oldster, I'm only 57 but feel the same. I actually studied at Altec Lansing in Anaheim in the 30s, and never DREAMED about being able to do all this in Java when I got my hands on my first IVIE RTA unit in the 70s. Enjoy, and keep in touch. http://jimkovacs.blogspot.com/
Guys, I am just getting ready to start using the REW..One thing I can't understand, at what level do you set the Volume Master on your preamp/ processor when you run the REW. I did quite a bit of reading but it seems I can't find the answer to this question...
Thanks...
I just bought a Berhringer FBQ2496 and am investigating it's many features with my 10 yr old laptop and my vintage RS 33-2050. I have also downloaded you REW. While my budget recovers from my afore mentioned purchase, I am looking at purchasing a USB sound card and USB/midi iinterface. Recently the Tascam
US-122MKII came into view. It has midi out & in and I wondered if this would replace the USB/midi adapter required for REW? With it's phantom powered XLR mic inputs, it would supply the entire suite of componnets
when I buy a calibrated mic.
I recently purchased a Berhringer FBQ2496 after downloading REW. I have been using a ten yr old laptop and a
vintage RS 33-2050 to explore my system. When my budget recovers, I will buy a USB sound card and a USB/midi adapter. Recently, I have noticed a Tascam US-122MKII. It is an elaborate device with USB sound card capabilities plus, midi in & out and XLR mic inputs with phantom power. Would this device replace the USB/midi interface? It would surely replace a seperate mic/phantom power device when I can buy a calibrated mic.
Also, try as I may I cannot create the test tone CD mentionned else where in this site.
Thank you for REW!!! It promises to solve most sub woofer problems.

My system (all home designed & built) :
a pair of three-ways, 2-5 1/2 woofers, 2 dome mids & dome tweeter arranged symetricaly around tweeters.
a pair of RS 18s in 5 cu ft boxes.
an ONKYO 555
a SoundTech A-300 amp driven by an ESP project 71, a Linkwitz Transform Circuit.
I am one of those guys that hate doing the same manual work many times and right now I am annoyed that my long post was lost because when I posted my long post it contained a link which incidentally is illegal for the first five posts here!?
Anyway, enough ranting.
Because of the same reason that I hate doing boring things many times over, I created a little utility that basically takes REW EQ Filter files and converts them into a usable preset file for some VST EQ Plugins.
The reason is that for my little music production studio I needed to correct the room acoustics for mixing purposes.
So I needed to do something like this chap:
[Room Correction with Plugin and Measurement by DozerBeatz]
The current support is ReaEQ which is a free VST Plugin and FabFilter Pro-Q which is a commercial one.
Thanks for the tip. The reason we have a 5 post minimum is that is helps to deter spammers from our site. If you would like, you can use the post padding thread to get to 5 posts - it is located here.
Tried using your Room EQ filter converter. Followed your txt file for setup etc. Drop the filter .txt on the converter ... But nothing happens!
