Many thanks for your thoughtful reply. Yes I'm using variable smoothing. Here's the MDAT files.

Hi all, I'm using the auto-EQ function on my main (full range) speakers. I'm navigating the process OK, and I'm generating good results. However I'd like to get tighter results at the low end of the band, approx. 300Hz and down. I've attached photos. The sweep image shows (top pair) raw...

I have a Flex 8 (no Dirac) that works fine with REW export files. I'm set to 96KHz. HTH.

I'm hoping for 40 measurements at one time but I hit a limit at 30. I've seen this is adjustable but - where? Can't find it... thank you.

UMIK-2 is rated to 125dB, as soon as I plug it in REW reports max input SPL of 114dB. I'm in the extreme nearfield so I'll fix my issue just by backing the mic away. But for the record, can I do anything about that 114dB limit and nudge it up to the limit of my particular mic? Thanks.

Hi all, I'm taking sub measurements very near the cone so SPL levels into REW are hitting & exceeding 114dB. I'm not sure if I need to adjust REW's input range or adjust my USB mic's gain? It's a UMIK-2. (trying to measure THD while very loud - I'm hunting down one misbehaving sub) Thanks!

I've already washed my mic grabs thru MSO and loaded the results into my shiny new Flex Eight. All went smooth and it's sounding great. OK, so I've got calibrated bass. I'll get used to this for a couple days, eyeball (uhhh... "earball"?) a main/sub level balance & then layer Dirac Live on...

I got it fixed. All this gear is lashed up with a slightly ugly USB network. I went thru the whole thing with D5 & a swab and immediately was able to take the 24 samples I actually need with a consistent error of only ten. So... flaky USB seems to have been the culprit. I'm good to go. Thanks...

Still getting variation. Attached file is just me grabbing samples quickly with no changes at all. Took all of 90 seconds? Errors popped up with quite different values to complain about. I've wiped & re-installed REW and turned HW acceleration off, I read that might help. No change. You...

Please ignore my earlier mdat file, invalid channel routing had bass sweep + pilot tone blended together. This one has correct audio routing and behaved better. I think I'm OK now but would appreciate your nod. I still need whatever magic timing tightness is needed to make MSO happy in a...

The mdat was the exact same measurement repeated 3 times, BTW. Might increasing the loudness of the fullrange timing ref speaker reduce my variability further? I can add a few dB to it. To verify, I can proceed & ignore warnings of this type knowing the files are going to MSO? ... and thank you.

Hi, is there anything in the attached files that can clarify what I'm doing wrong? I can not escape this error message no matter what I try. Thanks.

I don't think sommeliers develop their skill set by drinking beer.

Hi, is there an automated test in REW that maps out the upper headroom limitations of a speaker across the spectrum? I'm thinking of a repetitive sweep of slowly increasing amplitude and intelligence to stop the test once the speaker falls behind the signal by, let's say, 1 or 2dB. I know I...

Hi- Can the RTA function analyze a pre-recorded sound file? Like a WAV or similar. Thank you.
