I'm making automated microphone polar plot measurements with REW, Autoit and single axel robot. 5 degree measurement angle is mostly needed for hires plots and measurements are exported for polar plot construction as REW can't do this. That makes 72 measurements for full 360 degree rotation. I...

I posted the response below at Emotiva's website, but I thought I'd post here as I'm looking for more technical experience for my learning benefit (I'm an EE although audio isn't my concentration). I am interested in improving my system even more, but I suspect I crossed the diminishing returns...

In the REW Help file, chapter 14, "Minimum Phase", there is an "Excess Group Delay" graph. Is what is shown in the "GD" button of my sweep actually the excess group delay, or is there something else I have to do to show this? I'm trying to see if there is a delay between my subs and my main...

It would be useful if REW had the ability to generate various types of polar response views from a set of measurements, for example something like ARTA's directivity sonogram (example can be found in...

I seem to be having an issue with the waterfall plot. The first time that I generate it most of the decay is done by 180 ms but if I change the x axis from 300 Hz to 200 Hz, the decay goes beyond 300 ms. and I can never seem to generate the original plot again. The same thing happens when I move...

I'm quite familiar with REW. I just finished using it to tweak a pair of Bose 901 (series II) using a Behringer DEQ2496 for the "Active EQ" and all other EQ as well :) While I can't swear I hear a difference, I have learned to use (I think) the resonance finding tools in REW. In particular, to...

Dear friends: I've made some amazing progress using Acourate Convolver to linearize the response of my speakers/room. Sonically it's the most transparent room correction I've ever heard. Actually, it's the most transparent and musically accurate system I've ever heard. I decided to do some...

Are there any how-to guides describing measurement methodology for directivity plots? thank you

After finally installing the latest beta (9), I'm super-impressed. As a long-time ARTA user for loudspeaker testing and measurement there has always been a couple things missing from REW that kept me from completely switching over. I still use REW for all my room measurements, but speakers I...

I'm pretty sure REW will sum response plots or do other arithmetic operations (although I haven't tried it yet). Will it sum and retain phase info (I.e. sum complex number ) such that out of phase response will cancel? This would be a nice capability.

Hi, I'm using REW (both version 4&5 have this problem) with Win7 64bit, latest Java installed. I have MOTU 2408mk3 (with 424 PCI controller) and have huge problem. I do the calibration without problems - I see signals on meters, I hear the sweeps and everything sounds ok but I get absolutely no...

What are the pros/cons of simply using the default plot WinISD gives for a particular driver in a particular alignment. Please, for now, ignore room gain as well as room peaks and nodes

First, Great site, great software, really good stuff. After trying four different sub positions, I settled on the "best" location for sound and WAF reasons. One sub only and it is on the front wall between the TV and the right main; not in the corner but in about the 1/3 position along the...

Hey Forum, this is may be not a thread for discussion, it´s more like a question for the support team: The program runs very smoothly besides this one flaw I noticed: When zooming and/or scrolling the waterfall plots, the scaling and number read outs of the cursor change. For example: a peak...

so I guess I should go sealed 6.03 cubes is .707 for a Maelstrom-X I have up to 19 cubes available, all will take the same footprint a vented enclosure with the same airspace as a sealed enclosure will have the same or less excursion, and the same or more output... so if an LLT is useless...

There doesn't seem to be any of the decay information as i've seen on other plots here- even if i move the mic it still has this look - all help appreciated
