I thought a few tips on REW V5 might be in order, I'll start with some people may not have come across. Feel free to add any tips of your own.

  • Measurement (.mdat) files can be opened by dragging them onto the REW window
  • Impulse response (.wav or .aiff) files can be imported by dragging them onto the REW window
  • Filter set (.req) files can be opened by dragging them onto the EQ window
  • Move between measurements with Alt+UP and Alt+DOWN, go directly to a specific measurement with ALT+1 or 2 or 3…9
  • Move between graphs with Ctrl+LEFT and Ctrl+RIGHT, go directly to a specific graph with Ctrl+1 or 2 or 3…9
  • Hover over the name of a measurement in the overlay panel to bring up a tool tip showing the measurement notes
  • Move the cursor over the name of a trace to highlight that trace in the graph
  • If a measurement has been modified its name is shown in blue on the measurements panel
  • Use Ctrl+Shift+3 to apply 1/3rd octave smoothing, repeat to remove the smoothing
  • Use the Restore Last Removed entry in the file menu to recover a measurement that was removed by mistake
  • Right click in the overlay window legend area to bring up a menu that allows clearing or setting all trace selections
  • Under Windows or OS X double-clicking on an mdat file opens REW and loads the file
  • There are keyboard shortcuts for most things

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.

Best to All, Uncle Tom (tomegun) :eek:lddude: :clap:

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...

Best to set it at the level you normally use when listening, saves any surprises when you go back to normal content and forget to reset it :)

John,

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.

Your REW is fantastic, by the way!!!
