Hi Rocky, can you add a measurement without cal file in there and one withe cal file from dirac aswell to see the difference?

Just went to use REW again tonight and my lappy just crashed. Win8.1 could not recover, so seeing what I can salvage.

So, I did some playing this evening and confirmed that the AGC (automatic gain control) will mess with the dirac results. Also, it appears that sometimes the AGC will turn its self on when the mic is connected... Before each measurement with REW or with Dirac, this will need to be checked. Tony So AGC needs to be unchecked? But if DIRAC software has exclusive control of the MIC, does the Windows AGC still work? Can it be seen on the DIRAC results if AGC was active or not? Yes.

I'm going to do some more testing today, can you share your adjusted mic file ansat? Here my latest cal. Attachments:1-4cal.txt (18.64 KB)

AGC on does affect the results and not in a good way. Mine was on by default and I have not seen it turn back on by itself but I do check it each time I start Dirac. While Dirac is running and you're setting levels just try activating and deactivating AGC and you'll be able to see the changes in the levels on the Dirac screen. I did get an improvement in bass levels after running with AGC off.

I found that to get the mic working after the initial install on Win 7, besides all the microphone setup, the PC would still NOT let the application use the microphone. Message that the mic could not be used due to another application having control.
Right click on the task bar, bring up the TASK MANAGER. Select the SERVICES tab at the top of the Task Manager window. Find the AudioSrv - PID 1012, right click on that service and "STOP SERVICE"
The EMOTIVA application and the mic will now work, with no interference or background noise.
Remember to turn the audio service back on after you run the Dirac app.
This change also helped with any clipping issues and outside noise.

John Just for giggles I tried that, but Windows could not stop the service, access was denied. However, I was not getting an error that another app had control of the mic.

Just sussing out ideas here but what about using a xlr to usb adapter to use the umik with the cmedia cable.

Could someone please post some pics of the bottom end of the EMM-1.

I received mine today. Pluged it into 3 computers and they all loaded the driver on their own and seemed to work. Two of the computers have Dirac, one with W7 and one with W8.1. I didn't run Dirac, but I was able to set the mic to the desired level and it looked like it was working fine. Levels meters seemed to move up with the slightest noise in the room.
Cheers Mark

Thanks Socketman, If you have a calibrated microphone already and you want to calibrate for the emm for rew. What I did was take a measurement of all 8 speakers with rew (with all speakers set to large) then repeat the measurements with the emm (with the emm as close as I can get to the exact same position and with the cal file removed). I used the export feature in rew and exported all measurements as text and imported into excel. I got the difference between the two mics and averaged the differences (tossing out the data above 150hz for the sub and below 20hz for the other speakers) Take the frequency column and the difference column and load the to a new spreadsheet. Save as csv. Tony

You need at least 2 (main and a sub). The measurements cannot be trusted when they are outside of the speakers frequency range. Also, no matter how much work you put into this, you will never get the two microphones to measure exact to each other. As long as everything is within a 2-3 db, it will be the best your going to get. Tony

I don't know if this question has been already asked, is the mic calibration or precision will be altered if I use an XLR cable extension of 15' or 20' between the mic and the XLR-usb Emo cable?

Not sure. I wouldn't think so. But the better solution might be to use a USB extension. You get 5m total length to maintain USB 2.0 speeds.
