miniDSP UMIK-1 Calibrated Measurement Microphone

I’ve been using the UMIK-1 for years now. After five years of consistent use the first one went bad. This was my replacement for the exact same model. There is no single perfect measurement microphone. I supplement with a second microphones to ease speaker development; however, for room acoustics and finalized speaker measurements in general, this microphone is all you’ll ever need to validate acoustics. I utilize a more complex microphone, DAC, and amplifier combination to find speaker-driver offsets only during any speaker design phase. These driver offsets “can” be calculated using the UMIK and some careful calculations, but cannot automatically be accounted for with a single microphone/DAC combo. I’m lazy and have my adapted process; however, I have, and still can do a complete design with the UMIK only. UMIK’s plug and play connection with related measurements software is simply impressive. Although there’s a large learning curve regarding software tools like REW to become proficient with usage, this microphone makes it as simple stupid as any microphone could. Software developers are always working hard in the background to improve the software to make the mic more useful yet. For the price of the UMIK -1 you can’t go wrong for what it does. Great mic!

If you need to make acoustical measurements but don't want to invest thousands of dollars in equipment this USB mike from miniDSP is well worth it. It comes with 2 calibration files: Once you receive the mic you go to the miniDSP website, enter the serial number of the mic and then download 2 calibration data files. One of the files will say "90-degree" in the filename; That is for using the mic pointed at the ceiling. The other calibration file is for pointing the mic at the sound source, such as a speaker or speakers. This mic works very well with the free software program called REW (Room EQ Wizard). Though REW is free, it's full of great tools to help with room acoustic measurement as well as speaker measurements if you're building your own speakers. NOTE: The UMIK-1 mic has a build in analog to digital converter (DAC) so you DO NOT need to calibrate your sound card; The only time you need to calibrate the sound card is if your mic is analog; the exact procedure depends on the analog mic and interface you're using. With the UMIK-1, you just plug it into a USB port on your PC, start REW and go into PREFERENCES to set the mic as the input source, then load one of the calibration files you previously downloaded. Once you do that you are ready to test the mic and run a room sweep. Of course, the output of your PC (headphone jack) needs to be plugged into the audio system in the room you run sweeps for. Some have complained about the USB connectivity with this mic. So far, I have not had any issues. I will report back here perhaps in the future with an update if any problems develop. Otherwise, if you need a hi-quality calibration mic and don't want to deal with a analog mic and soundcard calibration, the UMIK-1 is the way to go.

I use this with free software called room EQ, and I’m able to with a calibration file. Get an accurate measurement of the frequency response of my speakers and room. Back in the day when I was younger and the speaker builder I would’ve loved this but it would’ve cost tens of thousands of dollars back in the 1990s. I don’t actually listen to this for sound recording so I can’t come in on that application.

Love this little mic, great for tuning home and car speakers to sound flat. It's a bit on the expensive side, but it's a very nice tool to have in your arsenal, and what you pay for in price you get back in convenience. It's small, lightweight, and the files needed were easy to find and download. Compatible and works with REW like charm!

I wanted an audio control mic but they’re hard to get rn and kind of expensive, so I bought this one. I was a bit nervous purchasing this as I’ve never heard of this brand and it’s quite a bit cheaper than its audio control counterpart. But my worry was very quickly wiped away. It’s super easy to set up, as you literally just plug the microphone into whatever recording device you’re using (in my case it was a dell laptop) and go, no apps needed. I bought a downloadable spectrum analyzer from True RTA and I had no issues with compatibility. I used the included tripod to station the mic right in the most center listening point for my gf and I. After a couple hours of listening and tuning in my living room, my surround sound has absolutely come to life (and it already sounded good before)! My girlfriend said she feels like she’s at a concert or at the movies and she never notices the changes I make to any of my systems. Idk how much better the Audio Control one would’ve faired compared to this one, but I definitely got my moneys worth just using it in my living room.

Nice mic that I bought to use with the Dirac room correction software for my receiver. While the mic itself is nice, the USB cable is too short to use as a calibration mic. The USB cable is only 6ft long, and while that probably works well for general usage, it's directly marketed by Dirac as the mic to use with their software. To properly do a room calibration, you have to move the mic to several listening locations and the 6ft cable length prevents that. Had to buy a USB extender cable to do the calibration properly. Should be sold with a longer cable option. Included cable has a USB-C connection to the mic with a USB-A connection at the other end, at this price should include an A to C adapter since USB-C is now the world wide standard.

Easy to order and fast delivery. Mic works great no issues

It works and did it's job. Feels high quality

يعتبر من افضل مايكروفونات معايرة الصوت للمسارح المنزلية وسهل الاستخدام ، تحسن واضح في جودة الصوت

Ótima qualidade Vc precisa baixar arquivo de calibração individual para esse Mic para usar Compatível com Rew e Dirac live Audyssey prometeu compatibilidade e até agora nada!

Trés bien. fais le job !

Quick delivery, great product thanks

One of the most important tools for getting the sound right. This is more than enough to setup a proper room correction. One of the most known and best for starting to use it as it is USB and recommended by REW. It can be easily used with eversolo streamers as well. Biggest improvments starts here at room correction not 2k EUR speakers. Well done for such practical product.
