Room Measurement Tutorial for Dummies Part 2

[dorirod]

Hey, thanks! Your opinions really helped me a lot.
Today, I didn't dwell on whether the two curves were aligned. I tried REW's EQ, but unfortunately, the effect wasn't very noticeable.I think I may have been too conservative when setting the EQ in REW, which is why there wasn't much difference(the pinkish one is after EQ, and the reddish one is the original).
Thanks again for your advice.

Are you sure the EQ took effect? Maybe stating the obvious, but REW just gives you the filters, you have to apply them somewhere (not sure what you're using for that in your chain). Try making a really noticeable change, say -10dB at 1kHz, or a low pass filter that kills everything past 1kHz and see if you notice it.

Oh, sorry, I just realized today that there was a problem with the output settings on my REW, which allowed me to bypass the EQ output settings in Equalizer APO.These are the results I measured after resetting the EQ and adding a smile curve (my friend strongly recommended this to me).

REW is an excellent measurement tool! It can also offer good correction results but the learning curve for FR modification is very steep and not something that can be mastered in a few days.
I would highly suggest finding a way to introduce Audyssey or Dirac room correction into the playback chain to smooth the below 250hz curve.
The most basic approach is to use one of these semi-automated programs for the curve correction and then follow using REW to measure the
results.

I checked, and currently I can't afford the Audyssey or Dirac hardware or software. In fact, their prices exceed the price of my audio system, ha ha ha ha. But thank you very much for your advice. I will consider it when my wallet is a little fuller in the future.

@amirm how can we pursuade you for Part 3.
That document (IMO) will be more valuable that yet another dac.

i want to get a microphone and measure my room properly. i currently own the RME Fireface UC soundcard so I am wondering, should I get the UMIK-1 for the sake of ease and then just in REW configure output 1+2 to RME (speakers) and input the UMIK-1? Or what's other option (besides the Behringer) in the 100$ price range.

UMIK 1 is a great option. I have heard of folk using a similar mic from Parts Express with good results as well but I don't recall the model number.

Just get the Behringer. I don't know why you would buy a UMIK-1 if you have an interface.

Would my setup work though?

a lot of people saying and providing data with the inaccuracy between the behringers, will make me always think if what im measuring is correct or not

People seem pretty happy the these calibrated MIC's, they sell several different models which they supply the calibration file for https://www.cross-spectrum.com/measurement/calibrated_dayton.html If you like overkill good tools that will last a lifetime and give great performance and satisfaction every time you use them take a look at Earthwoks M20 or M23.

I've been using an Eversolo EM-01 with REW. The EM-01 is roughly half the price as a UMIK-1 (at least it is for here) and you can buy it right off amazon and have it delivered right to your door: https://www.amazon.ca/dp/B0DP9VK96R?ref=ppx_yo2ov_dt_b_fed_asin_title

Downloadable calibration files (keyed to the serial number) for horizontal and vertical orientations.

I'm just using an inexpensive amazon mic stand, which is surprisingly heavy and sturdy: https://www.amazon.ca/dp/B0DB5NVC2V?ref=ppx_yo2ov_dt_b_fed_asin_title

The mic "clip" from the Eversolo screws right into the end of the boom.

I'm all analog though (stereo 2.1) so for me, it's solely used for measuring and that's it. the Eversolo seems to be working well so far. I've already made significant improvements in the room's SQ with it.
