Sweet Room

[tategoi]

I had some time earlier this week and decided to have some fun with my newly acquired Umik-1. Downloaded the REW and watched a few video to learn ho to use it.

1. I normally had the SAM set at 25%. Anything higher the room nodes are more audible. A few measurement on REW confirmed my observation. There was a boost of approximately 5 dB at frequencies up to 50 Hz. Decided to set it at 0 as my reference measurement.
   
2. Calibrated the Umik-1 by uploading the calibration file to REW. 
   
3. Bought a long USB cable to connect the my iMac (just behind the listening position) to the O'dA.
   
4. Set the reference calibration level to 75 dB with pink noise. 
   
5. Start the measurement. Took a few with the Umik-1 set a few inches to the right, left, front and back from my usual ear position at the sweet spot. 
   
6. Average all the readings and apply VAR smoothing to the curves.
   
7. Uploaded Harman's house curve to REW.
   
8. When performing EQ I chose rePhase as recommended in this forum.
   
9. Only performed EQ on frequencies up to 200 Hz. 
   
10. Only taming the frequencies, no boosting as recommended in this forum.
    
11. Translated REW filter settings to Devialet EQ.txt template in the Alternate section while setting the Main as null (no room correction) for A/B testing 
      eq.txt (Size: 1.98 KB / Downloads: 14)
    
12. Copy to SD card with and reset the O'dA.
    

MAIN: no correction. ALTERNATE: Sweet room. 
   

The effect is the bass is softer but less muddy and better defined. And if I want more oomph at low end I will turn up SAM.

I read that the Q value should not be more than 10. My Q goes as high as 35. I have yet to figure out if there is a way to limit the Q value when performing the EQ in REW. If anyone knows please advise.
