I am looking to buy cheap measurement usb microphone in Europe. I found 3 potential candidates, UMIK-1 by miniDSP, UMM-6 by Dayton Audio and MM-2 by Omnitronic. I have never heard about this Omnitronic company before, they appear to be from Germany. Their microphone is by far cheapest, it cost just 54,90€ compared to 99,00€ for UMIK-1 & UMM-6.
Just like the Crosslabs in USA who sell UMIK-1 with individual calibration file, akulap.de sells calibrated UMIK-1 for 122€ and MM2 for 94€. Not only is the MM2 cheaper, its also has much higher maximum spl 133db compared to 105db of UMIK-1. Ofcourse, this makes it much noisier but I am not going to record real life band, I just want to measure frequency response and distortion.
The closer the sound pressure is to the SPL limit of microphone, the more will the microphone distort, that means MM2 is far superior to UMIK for THD measurements, the high noise floor is easily reduced possibly to infinite low value by using sufficiently long averaging. The Dayton UMM-6 max SPL is 127db, a midway between sensitive UMIK-1 and high SPL tolerant MM2.
I have zero experience with any of these measurement microphones, which one is best?
1. Do I need Crosslabs or Akulap calibrated mic or are the factory calibration files accurate enough?
2. Which of these 3 microphones is highest quality/reliablity?
3. Who are these Omnitronics? Is this MM-2 their unique microphone or is this just rebranded mic?
4. What are all significant differences between there 3 microphones?
