Looks like a bug in the particular version of REW I've been using. When I load the mdat file, it proves you're 100% right. However when I was working on a fresh set being created, never saved and never reloaded, the curves were different. Once saved and reloaded, the differences are gone!

Hi, You mentioned your document isn't maintained anymore, which is quite normal. I took several measurements in a one month period and I perfected your method (no offense intended) for my patricular needs. I'm happy to yield the credit to you. I still use REW 5.40 B 56. If you notice...

I'd be happy to believe you, but I took an IR measurement and an RTA measurement, and the curves are slightly different at the two ends of the spectrum. As soon as you add the RTA curve to the microphone calibration curve, the result is identical to the initial IR measurement. They then overlap...

Granted, but my point is, there is no cal by default when you measure pink noise with RTA, is there?

How can it be ?

Hi, Correct me if I'm wrong, but your method don't to seem to take the mic calibration into the equation. If you want to have a faithful representation of the frequency response, you should use arithmetic operations and add A+B the mic compensation curve to the measurement. I played a lot...

Oops. Anyway. Traces 1-3 are sampling taken with the last conv filters (created last november) at the MLP, after I changed several things in the room and also changed the woofers. They're there to reveal the imperfections of that filter which was tailored for a different room settings and...

Thanks for your reply. I had a test run. I placed the mic on its stand, went upstairs to press the record button, managed to go downstairs and move the mic carefully, put the mic back on its stand, then went back upstairs to stop recording and save. Not bad so far. Like DIRAC I'd say. I...

Hi, 1 year since this message. There has been a speaker change, a lot of changes in the furnitures, correction to the room, 2 doors added, 1 alcove hidden so I guess I'm ready for a new set of measurements. System is stereo (2.0). I'd like to use the method you described. However the...

I experienced inconsistencies with the delay to the acoustic timing reference in the past and that's the reason I make 3 measurements and discard those out of range. Mic is UMIK-1. However I was in a hurry here for a quick test regarding polarity. Now I'm interested in determining what is...

Is there a changelog somewhere?

Oh! That's so much simpler. Thanks a lot!

Hi, Let's suppose I took measurements with the UMIK pointing towards the ceiling but used the flat mic cal file. To remove the cal file influence on the L measurement, is it correct to import the flat cal file as F then generate |L|/|F| as L1 ? Then to correct the measurement with the 90deg...

This happens to me on windows every time I want to use the EXCL:Speaker which is already used by CamillaDSP as playback device in exclusive mode. Killing CDSP gives REW access to it.

Oh! Thanks a lot, I'll set that up. I'm not sure myself. Learning how to use that new toy and from time to time as I read and learn more about it, I have the feeling what I already did could have been done a better way, so I test again and compare. I was used to the stable version, so I'm a...
