Hi Ofer, yes, I have been running AL under W11 for a couple of years with no issues. Same with HLC.

@vego99 from the Radian website: "The 950 driver delivers clean high frequency sound with ultra-low distortion. This reduction in 2nd and 3rd harmonic distortion is only possible with our large format 4" diaphragm, 5 slit phase plug and Mylar suspension." Key phrase: 5 slit phase plug. These...

Yes, these are constant directivity waveguides and as such requires constant directivity eq: https://sound-au.com/project173.htm My JBL waveguides (with the large format 4" compression driver) requires the same type of eq along with JBL M2's and other constant directivity waveguides. A good...

@Cornelis Huizinga and Arch's article on Multichannel Digital Room Correction with Audiolense XO.

@whoareyou it is hard to tell from your screen shot in the first post what the dB vertical division is? Also, probably more constructive to see the correction filters response... complete with vertical (1dB per div) and horizontal scales. Yes, AL will make up the gain difference. But if there...

@dima1stg there still appears to be some confusion... There is nothing wrong with REW. There is no timing instability. Period. And nothing to do with sample rate. The issue is 2 clocks (derived or otherwise) between the USB mic and audio interface. And as I said in the post above, it is not...

Perhaps there is a bit of confusion with the OP. First, I am not the author of Acourate, that would be Dr. Ulrich Brüggemann @UliBru here on the REW forum. 2nd there is no issue with UMIK-1 or 2 using the "Measuring with file playback" method as described in John's REW Making Measurements help...

Same issue here. Reported to Bernt.

@NMixes Jeffrey has you covered and congrats! It is a nice mic and one of the very few that publishes it's distortion profile. @yoav yes, this is the same answer and calibration file I also received a while back. Sorry I did not post it time when you asked your question.

As mentioned to you before, HLC does not automatically load different channel format .cfg's which is in my backlog to be completed. I don't know anyone else manually editing Audiolense.cfg files, as HLC will handle both absolute and relative paths. No-one else has reported this issue. As far as...

@whoareyou Problem solved, user error. I measured Bernt's convolver some time ago as a Beta tester, but I can't find the measurements as that was 2 computers ago. But I do remember with a Dirac pulse loaded it was flat frequency and phase response, as it should be. I have also compared HLC to...

@2234rew work has me too busy. One word: experiment. :cool: Give it a try and see how it integrates in AL sim and how the correction sounds. Try a correction with the chair in the way and one without. Try pointing the mic straight up and use the Earthworks 90 degree generalized mic cal file...

Sorry, I missed that, but as you have found out from @2234rew it is a high quality MCH converter. And now you are getting consistent and repeatable measurements with the timing intact. It does make an audible difference. (PS. I own an mk5 as well).

It is always good to inspect the actual correction filters themselves (i.e. chart view details: correction) to see if: a) you are getting any narrow band artefacts in the frequency response, and if yes, then reduce the amount FDW cycles in the TTD sub window unitl it goes away. b) with the...
