Amen to that. Stereo (or multichannel) is essentially made in (and therefore for) very dry (and even near-anechoic) environments. While it's true that spaciousness and envelopment is caused by reflections, these reflections should come from the recording, not the room. This is where the 'wide dispersion loudspeaker' and 'room reflections are good' theory falls flat on its face.

I added the 8" OC 703 side panels and fixed the impulse peaks too.

For some reason when I added the side panels it messed up the waterfall. Could be because the side panels are just setting on top of the bass traps and must be wobbling at certain low frequencies.

This is very interesting, I've never had my waterfall plot look worse after adding absorption! I even rerun Dirac, and same results. Going to eliminate air gap behind panel tonight as that should stiffen it up.

Might just be LF noise. Alway good to run each measurement a couple of times and verify that the results are constant over time. I always do at least two consecutive measurements.

It could be, but I did 10 measurements (was trying to fix impulse plot at the same time). I will make sure all ventilation is off and retry before moving panels against wall.

EDIT: I think I remember tucking the mic's USB cord into the chair. Now that could really be messing up my measurements! Thanks a bunch for jogging my memory. Tucking the cord in between the chair back and arm was really stupid!

I received my microphone order on 12/28, started setting up everything in earnest on 12/29. When I went to the site to download the configuration file for the microphone, I could not enter the number from the label. The label had been smudged at some point, and the first number in the sequence had been rubbed off. Tried a UPC code reader but the curvature of the mic could not be read by my phone.

I emailed their support, gave them my order number and explained the issue I was having. Less than a day later I had a response that solved the problem.

Very helpful, very responsive.

Now if only I could get the HDMI connection from laptop to receiver to be 5.1 as it used to be, prior to Win10 instead of 2.0 stereo....

I'll figure that one out though, lots of info on that via google.

Interesting, was this directly from miniDSP ? I have the exact same problem with the number being smudged off. And I have also tried a code reader before even reading this post, but the curvature was in the way.

Difference is I emailed them on Saturday this past weekend (with my order number), but I am still waiting to hear from them. I got an email from support@minidsp.desk-mail.com as confirmation there is a case opened, but no follow up / resolution yet.

I guess if I don't hear by Saturday, I'll send them another email.

I used the link from the Web site - Support / Contact US, did you maybe use another email address ?

How did you solve the problem, were they able to give you the correct serial / calibration files, or in some other way ?

I have not read yet through all the 590 pages (I will by end of this week, I promise ! ), so not sure if this yet been posted.

Many have problems with ASIO detecting their UMIK-1 device (as in Idle / Not active) in the ASIO control panel.

When I tried to use REW / ASIO for the first time, I tried to use HDMI from PC to my AVR , and UMIK-1.

My Playback devices were configured to use all 7 speakers (L,C,R, 2xSR, 2xSB).

I got the same problem with my UMIK not being detected as active by ASIO. I tried the workarounds in the "Getting started with REW guide" but interestingly as soon as my UMIK would become active, my HDMI output would go idle, if I was able to get my HDMI audio output active, my UMIK would go idle, no matter what I did.

I was able to finally resolve this when I tried going to Windows Playback devices, clicking on Configure, going to Speaker Setup, and starting to remove speakers to be used (starting from the surround back, and trying again, then removed surround rear and tried again, at some point .. maybe when I was left with L/R only, all of a sudden it worked .. I then went back and started re-enabling speakers in the reverse order and it still worked.

So now I have all speakers enabled, and restarted my PC / REW several times, but have no issues at all. Full HDMI output and UMIK active and working.

Anyway, just wanted to post this as maybe another type of a workaround people can try if having problems. I have no idea whether it will work for everyone though
