Frequency Response
Frequency Response is a curve that shows how strongly an audio system reproduces different parts of the frequency range. A frequency response is related to its "impulse response" (the pressure signal that a speaker or sound system would make if it were fed by an extremely short pulse).
Impulse Response
The purpose of a Impulse Response is to reveal how the frequency response of a loudspeaker is affected by the room at the location of the microphone.
Harmonic Distortion
Harmonic distortion is the unwanted addition of new tones to the original audio signal. These distortion products occur at multiples of the original frequency and are centered on the harmonics of the original. For example, a 1kHz fundamental that has been subjected to harmonic distortion will produce energy at 2kHz (2nd harmonic), 3kHz (3rd harmonic), 4kHz (4th harmonic), and so on.
Cumulative Spectral Decay
A waterfall (or CSD) illustrates, on a 3-D graph, how a speakers' energy decays or is radiated over a range of frequencies. Waterfall plots are used by driver and loudspeaker designers for driver selection, to identify resonances or reflections, and to view driver and waveguide behavior.
Automatic EQ
The EQ window allows you to customize and visualize the effects of filters based on the measurements taken with the UMM-6
SPL Meter / Spectrum Analyzer
The SPL (sound pressure level) meter allows you to measure how loud your source is while the spectrum analyzer shows you the relative SPL of frequency bands.

I've used this for room correction on multiple systems. Love the hard case and included mic stand clip. I'm a big fan of DIRAC and desktop room correction. The improvement is undeniable. Everyone with a desktop 2.1 speaker setup should own one. REW and EQ APO are a must.

I bought this mic about year ago when I bought a new SUV and upgraded the stereo. I used free software on my laptop to make measurements and adjustments to the EQ and amp. I now have the best sounding car stereo I have ever owned. Because I'm just using the 13 band EQ built in my stereo, I couldn't get it perfectly flat, but it's fairly close. I could really see where the frequency dips were and compensated for them.To get the calibration compensation data, all you have to do is go to their website and type in the serial number. I kept a copy on my computer in case the company ever goes out of business (unlikely, but better safe than sorry). They say you should get it re-tested every 5 years, but I doubt it would change significantly enough to be worth getting re-tested unless you are a professional.

The mic. works just as promised. The software is like a 3-credit course. Be prepared.

Habe dieses Mikrofon zum Einmessen meines AVR mit Dirac verwendet und funktionierte einwandfrei. Das gleiche mit REW eingesetzt und bin mit den Ergebnissen sehr zufrieden

Used to tune the audio in my car, I'm very happy with the results. Build quality and materials are also excellent. Seems to be solid aluminium.

This is a pretty good microphone to use for home or vehicle. The only downfall is the size of the microphone and the calibration file from Dayton doesnt work on SMAART unless you alter their calibration file. I setup (FS -20 @ 94db) and compared it to one of my ISemCon microphone with 85db, pink noise, and it came relatively close. Then I created a calibration file myself using my ISemCon as reference. It's definitely worth it, if you are using it for home or car. I wouldn't use this on the field to calibrate a large room, I'd probably use it only for SPLs and to keep RTA running at Front of House. 4/5 score mainly for the size of the microphone. Performance is great

Tenia mis dudas para comprarlo pero al final me decidi y funciona excelente. Lo utilizo con el DSP Helix la computadora lo detecto sin problemas y las mediciones que hace son bastante precisas. No es un microfono profesional pero si eres un aficionado te puede funcionar muy bien y te ahorras una lana.

This was cheaper than the competitor Umik-1 so I went with this instead. No complaints, easy to get the calibration file and worked seamlessly with REW for doing measurements on my home theatre system.

After Calibration this mic performed nearly exactly the same as our B&K 1/4" mics in an anechoic chamber. Measurement made with Fuzz measure. I'd give it 5 but the foil cal fell off easily suggesting cheap manufacturing.
