I'm just beginning to look into using REW and I'm looking for the best way to get started on a beginner level. I came across the MiniDSP UMIK-1 and noticed that it "integrates seamlessly with REW". I'm curious as to what I will need besides the mic to use REW.
I'm intending to use REW primarily to graph the frequency response of my sub and mains in my room. From there, I plan to use the EQ in my processor (receiver) to take out the dips and peaks for each of those as best I can.
I'm passing audio to my processor (receiver) via HDMI, if that matters.
Basically, if I have a computer with REW 5.1 and the UMIK-1, what else do I need (if anything) to begin taking measurements of my speakers?
You will be using the laptops sound card so:
1. Basically a cable (RCA or HDMI) from your laptop to the receiver.
2. With the RCA you use the headphones or similar output to your receiver. With the HDMI i haven't used this connection.
I highly recommend getting the UMIK from Cross - Spectrum.
When you receive your mic and connected REW when opened will ask:
1. Do you want to use the UMIK as a mic
2. Then ask to load the UMIK calibration file.
You do not do the soundcard calibration, just above.
I have both a laptop and a desktop, both running Windows 7 64bit.
What is the benefit from ordering from Cross Spectrum? As far as I can tell, it just includes the calibration file on a thumb drive, which I can download for free from the MiniDSP site? It also has some other info/charts, but I don't feel like I need those?
Would a stereo 3.5mm to Red/White RCA cable do the trick?
I am new with this like you. I just ordered the UMIK from Cross-spectrum because the calibration is best, highly recommended by the A/V community. After thousands of dollars of gear, a few more bucks is worth it to me to make it all sound best. It's a little more money but it's supposed to be worth it, and mention HTS and you get a discount too.

I would use the laptop. If you use the desktop running on power that will generate noise.

Yep but it pays to have a splitter, REW sends mono test signals. I have one at the receiver end. E.g if you want to measure the left speaker just disconnect the right speaker wire.
I am new to REW as well..... The UMIK seems like the easiest option to get into using REW.... Is this easier than getting a Behringer EMC8000 etc? I have a pc with sound cards etc...
Again, Phillips, thank you. Looks like your the only one trying to help a person out, sadly.. Im beginning to wonder why im here, and not there.
Downloaded the ASOI drivers, but im still not getting enough sound to produce a usable cal file. I've turned the volume all the way up, subs and speakers. Like I said before, im sure it;s some setting in the laptop that im missing. Man I wish you had the same setup I have, lol.. :T
Hopefully this hasn't been answered somewhere else, but which UMIK-1 calibration file do you use, the "Narrow Band Response" or "One Third Octave Band Response"? Do the 0, 45 and 90 selections of these files refer to the position of the microphone?
Hi
I used the Narrow Band Response. I recall that was recommended by CSL in their PDF file came with the mic.
Yes the 0 45 90 refer to the mic position. I do room measurements using REW so I point the mic directly at the speakers from my listening position. So that is the 0 position.
I use REW to check acustics with my stereo system that works only in analog domain (no HDMI input).
I am using external soundcard Behringer UCA202 with my laptop.
I use only left chanel card output with mono signal, then Y spliter to feed both hanel of my preamplifier.
I thought that loop a right unused channel of the soundcard will yield to beter accuracy results.
When using the UMIK-1 the soundcard is only used for output, input comes from the UMIK-1. There is nowhere to connect a loopback to.
