I've been using another brand of calibrated microphone for quite some when tuning my SQ car audio system with my DSP. It's been frustrating to say the least. With this microphone and the free REW (Room EQ Wizard) software available online, I've been able to make some major changes to my tune that I wasn't able to previously. This is hands-down the best money I've spent in a while in terms advancing the sound quality in my system. My system's sound has improved noticeably since I purchased this. If you're in a similar position, I cannot recommend this microphone enough. Excellent purchase!!!!I learned about this microphone while trying to optimize the frequency response of my stereo system.Then I asked my self which bothered me more: the frequency response, or all the frequencies I couldn't hear because they were masked by household noise?Between HVAC systems, range hoods, bathrooms fans, refridgerators, computer fans, and other appliances, homes are awash in noise. Sadly, it is difficult to get any kind of reliable comparisons on expected noise, even with long web searches.For example, I found a web site with noise ratings on dehumidifiers. They even described their methodology for testing. I tried a couple of the systems they had rated. To my ears, the "noisier" of the two was QUIETER in my home.Clearly, I needed some way to come to grips with all this noise.Turns out this microphone is an ideal tool to do just that.I'll use the dehumidifier example again. I measured both units with this microphone and REW (Room Equalization Wizard) software. I was able to replicate the numbers from the review website by following their placement notes. Then I was able to move the microphone closer to where I would be hearing the units.Sure enough, the overall RMS loudness matched the review site. BUT this microphone with REW showed thath the QUALITY of the noise of the unit that was louder to me had much more sound in the frequencies where most of my music and best hearing is!So, this tool is great for getting a grip on noises around the house. I will continue to use this to measure things like heating and ventilation fan and compressor noise, or appliances. It will be great to hook this up to a laptop, go to a appliance store, ask to have their quietest refridgerator turned on, then MEASURE the volume AND quality of the resulting noise!Maybe when I'm done with that I can use this to take a look at frequency response...I bought an Emotiva XMC-1 Processor about 7 months ago. Amongst that I have an svs ultra tower 7.1 surround system and an svspb4000 sub. Nice setup or so I thought. The mic that came with the from emotiva would give too many varying results and too many disappointing playback results especially way too light in the sub area almost every time. I decided to try the ECM8000 from Behringer becuz it was cheaper @ $55 instead of UMIK-1@ $100. The ECM800 $55, driver $45, phantom power $25 and last but not least hdmi $8 total of $133 dollars. The ecm8000 did a flat response, but again the sub was too lean until I went into Dirac and changed the sub settings which didn't sound the best. Not bad though. I was not happy with dirac so far. I could send all the extra sh#$t for the ecm8000 back except the mic. If anyone has an emotiva $2500 processor or higher price. Get the umik-1. The emotiva mic was way too sensitive so when it runs dirac it wants to turn the sub way lean. Tweaking it every calibration gets old but , I could get it humpin. Now the UMIK-1 was a whole new ball game. First calibration made adjustments to dirac. Im just used to do n that. Played some movies and music sounded good but, I wanted to play more. Went to dirac omg my file didn't save. 2 nights later I ran dirac again with the umik-1....same results again. I decided not to touch the sub section this time and just give a whirl Wow..what a world of a whirl it turned out to be. This mic is less sensitive so there for it needs the subs to be present and it is very much present. It picks up down to 8hz or so. It sounds like a real movie theater now. I missed all of this thunder and over all detail for what!!! Minidsp offers other sound correction programs and how to set up guides. I think it's a very nice touch for " just buying" their mic.Great product and worked like a charm. Tons of youtube videos online on how to utilize this with the REW free online program.Using it with free REW software via pc in my car ,Type C connection is much better then Umik1 v1's micro B interface ( only type C version is available today )Does the measuring job and compatible with car DSP ( Helix / Brax ) to have the min adjustment automatically from REW to DSP.Calibration file is representing the batch produced,if you are really in to very deep analysis , they also produced 2x priced umik 2 having 24/192 KHz instead of 24/48 of Umik 1 ( umik 2 ; said to have individual calibration file )If you really want to dial in your subwoofers and speakers this is a must. This along with REW is a real winner.Great results measuring with UMIK-1/RoomEQWizard (REW), mixing gain/phase and creating convolution files in rePhase, then finally playing them in HQPlayer/Roon. Many other uses, and much more to the story. Please see roomeqwizard.com and rephase.org. Well worth the money and effort.I used this in conjunction with the free software Room EQ Wizard. I have two subs on my stereo setup and needed to correct for sound issues. This mic is very well made and once I got the software running it was really helpful to get sound readings on my room. It showed me a better crossover point and helped me to correct a room null at 55 hz. Super pleased. I was asked to rate this product by Amazon on "sheerness" which is defined as "thin, fine or translucent". It is thin and fine. So 4/5 stars for sheerness.I would buy this again in a heartbeat.I needed a measurement microphone in order to use Room EQ Wizard software. This worked perfectly connected to my Mac. To set up properly, all one has to do is download a configuration file specific to the serial number of your microphone (all the details come within the packed documents). I was up and running within minutes.The combinaton of this microphne and Room EQ Wizard has massively improved the sound from my hifi set-up.E' un microfono per rilevazioni (quindi non pensato per registrare la voce) che ha il vantaggio di non richiedere un pre col phantom power. Questo si traduce in rilevazioni più "omogenee", non essendoci un altro elemento (pre) che potrebbe falsare le rilevazioni introducendo del rumore. Il microfono ha anche un spl integrato che lo rende equivalente a un fonometro. Viene rilevato automaticamente in Windows senza l'utilizzo di alcun driver e dal sito miniDSP è necessario scaricare (usando il seriale) i file di calibrazione (una versione a 0° per puntare direttamente lo speaker (configurazione stereo) e uno da 90° per puntare il soffitto (configurazione surround)). Funziona a 24bit/48KHz, il che lo rende sulla carta incompatibile con alcuni software automatici di calibrazione speaker (es. Sonarworks).Basta inserirlo in una presa usb del pc, aspettare qualche secondo, il tempo che venga riconosciuto, e potete cominciare ad usarlo.Io lo uso con REW, ma va bene anche con altri software.Dispone di un file di calibrazione individuale che si scarica dal sito inserendo il numero di serie del microfono, cosa veramente ottima.Prima usavo il Behringer ECM8000, cha ha fatto onestamente il suo lavoro, ma è più scomodo perché necessita di un pre microfonico con alimentazione phantom, la cui linearità può inficiare le misurazioni ed inoltre l'ECM non dispone di file di calibrazione individuale.Chiunque acquisti questo microfono di calibrazione sa quel che sta facendo. A differenza di microfoni come il monacor ECM-40, l'UMIK-1 è prodotto da un'azienda seria che fornisce i file per la calibrazione del microfono.Qualsiasi persona che lavora nel mondo dell'audio dovrebbe usarne uno per calibrare i propri altoparlanti.Sfortunatamente non è compatibile con sonarworks se non mediante l'utilizzo di asio4all poichè l'unica frequenza di campionamento settabile è 48khz mentre sonarworks supporta solamente la 44.1khz,Works. Well. As expected
