    I have always used REW with a calibrated ECM8000 mic and a Steinberg UR22MkII sending the output from the UR22 to the analog input on my AVR for the speaker being measured. That setup used Input 1 and Output 1 as loopback. Input 2 connected to the mic and output 2 connected to the analog AVR...

    FWIW, I have been using the V5.20 betas and noticed a lot of nice new features added to the measurement window which includes auto-documentation replications and incremented numeric measurement names. Another useful feature would be to prepend or append an indicator of which channel is being...

    Hello, This is my first post here and first stab at REW after lots of reading and video watching. I wanted to share what I did as a workflow and the graph I got so that someone can help me further as the results do not make sense to me. 1. Installed REW 5.19 with java 2. Connected my miniDSP...

    Although I had successfully measured amplifer distortion at the loundspeaker terminals, when I did this a second time I managed to damage my inbuilt PC sound card. I was not using a voltage divider probe since I knew the AC levels were no more than 250mV. I don't fully understand what went...

    I'm trying to measure a pair of new Goldwood drivers I received for Christmas that I plan to use for outdoor speakers. I'm following the instructions provided online. The calibration worked just fine. I'm using a USB Soundblaster XFi soundcard switched to headphone out. I have a 100 ohm...

    I ran some sweeps with my subwoofer at 10 positions and then did an Average for those which I then use to create EQ filters. The Average looks pretty much as the middle most position of my sweeps so is there more "information" to work with for creating the EQ filters with the single...

    My Basic question is how to measure the correct [phase property] of a speaker system. I obtained TSP signal thru the DUT speaker and the mic. Then, t=o set at IR peak. This means that the sound fly time is removed. So, The Phase must be displayed correctly, I think. It looks working well. My...

    I’m in the early stages of incorporating acoustical treatment into my theater. I downloaded the REW software with the intention of using it to identify a relevant baseline to compare post treatment results. I’m running windows 7, am using a Radioshack 30-2055 SPL meter and a BehringerUCA202 as...

    OK so just wondering not sure I am actually doing this correctly. What is the process for house curves. I do a measurement no Sub just the front three. I played with small /large settings and got the best reading. eventually and settled on small L/R and Large for centre. I have Bookshelfs and a...

    Hi all Hopefully you can suggest some help for me please. I'm new to REW and wish to use it for impedance measurements. I have a set up problem that I can't find any advice on how to solve this. I have a Soundblaster SBX ProStudio and Windows 10. I have set up the Soundblaster in the...

    Hi All Just wondering, if for the Measurement mic in REW, if I can use the Anthem mic I had with the Anthem ARC program. I no longer have the receiver, however I can buy the Mic and stand and Calibration files for about half the cost of a UMIK-1

    I can't seem to enlarge the notes window for calibration measurement. I guess its kept intentionally small, to allow multiple measurements to be tabbed. When doing a loopback cal then there are a lot more details than the notes window size can show, especially for the soundcard setup. Yes I...

    I'm new to time-domain measurements and have a question, because most of the time I take things literally. But first, some background: It's no secret REW is able to use timing references in measurements to calculate system delays so that separate measurements have the same absolute timing...

    I'm new on this forum, so sorry if this has been discussed earlier. We've made tons of measurements during 2008 to 2016 and all stuff were saved as .mdat and exported to .txt and finally to complex excel sheet, as sort of database. Now, for reason I can't tell, we updated v5.0 to latest...

    I've exported a set of measurements as text so that I can analyze them using Matlab. I'm running into trouble extracting an impulse response from the magnitude and phase data that are exported. To be sure I had my ducks in a row I first simulated an impulse in Matlab and added a bit of noise. I...

    I have a notebook with a Umik-1 microphone. I have some questions on measuring car audio as it seems you would do it differently from rooms. 1. It seems that you would use mic pointed to the windscreen with averaging of 4-6 positions around the head area with sine waves to get the true FR of...

    So I successfully attached a UMIK-1 mic, downloaded the calibration file and the latest beta of REW 5.17 beta 14. I set the mic to unity gain in the audio midi devices and to 48khz input. Since I am a stereo listener I just have two speakers - about 10 feet apart toed in to point to the...

    I have a 5 meter rca pair connection from a desktop to a pair of rca inputs of av receiver,the rcense is at default settings 100.0 is it o.k.?

    Hi, i make SPL (dBZ) measuremet with mi UMIK-1 and Rew in RTA in third octave, then export the measurement as a text, but the text file give me a lot a frecuency beawteen the third ctave band, i want to know if i have to do the energetic sum of SPL in each frecuency Third octave band, or just...

    I noticed something very odd. When I do a measurement of both my speakers at once, I noticed the measurements from 6khz and up is wildly inconsistent. Sometimes the measurement for both speakers will be lower than the measurement for the individual speakers! Other times it will look the way I...
