Acoustic Measurement Tools

MiniDSP is pleased to introduce the UMIK-2, its second-generation omni-directional acoustic measurement microphone. The UMIK-2 has everything that made the first-generation UMIK-1 one of our best selling products, including a convenient plug-and-play USB connection and a unique calibration file for each microphone to ensure accuracy.

However, the UMIK-2 is also a significant upgrade in performance and functionality. A larger 1/2-inch microphone capsule provides lower noise and lower distortion, which is preserved by the 32-bit ADC (analog-to-digital convertor) built into the microphone shell. Furthermore, sample rates are selectable from 44.1 to 192 kHz for compatibility with the widest possible range of measurement and recording software.

The UMIK-2 is of course fully compatible with REW (Room EQ Wizard) and Dirac Live (version 3 and later). Driverless operation with macOS, Linux, Android and iOS, and a supplied ASIO driver for Windows ensure simple integration into many other measurement and recording applications. With the UMIK-2, miniDSP once agains stretch the limits of affordable acoustic measurement gear.  Let the measurement fun begin!

Unique Calibration File Download

All UMIK-2 are calibrated with a unique calibration file. In addition, a unique auto-generated 90-degree calibration file. To download the calibration files, look for the 7 digit Serial Number found on the body of the microphone.

  1. Enter the serial number in the form below (three digits then four digits e.g. 810-XXXX).
  2. Your calibration files will automatically download in most browsers. If not, click on the links provided to manually download.

Which calibration file should I use and where to point the UMIK-2?

We provide two calibration files to be used depending on your application.

- For stereo system (e.g. 2ch dirac live, single speaker measurement), use the 0deg file and point the UMIK-2 at the speakers
- For multichannel system (E.g. 5.1/7.1) or a surround application where multiple speakers are spreadout around the room, use the 90deg file and point the UMIK-2 at the ceiling.

I stumbled across miniDSP as I looked for REW-compatible measurement microph and updated the firmware. Finally, I downloaded the newest beta version of REW, opened it and the UMIK-2 was immediately recognized. Over the course of a morning, I measured and tweaked all three systems using the UMIK - finding and addressing the audio issues that I just couldn't quite put my finger on. If you are an audio enthusiast, this is a great a great tool to have in your toolkit. Solid c. Current generation USB-C connector on base of microphone. Easy to download calibration file. Excellent integration with REW software. Most important, solid audio measurement results - exactly what I needed.
