UMIK-2 USB Reference Measurement Microphone - Calibrated Accuracy

In this review of the UMIK-2 USB Reference Measurement Microphone, the bottom line is simple: this is a measurement tool aimed at audio engineers, home theater enthusiasts, and DIY room correction users who need a calibrated, reliable microphone for objective measurements. The standout reason to buy is its unique per-mic calibration file that delivers repeatable frequency response readings across applications like Room EQ Wizard and Dirac Live, while driverless operation on macOS, Linux, iOS and Android makes it easy to deploy in mixed environments.

Key Features

• Unique calibration file: Each microphone ships with a specific calibration file so measurements reflect the actual microphone characteristics rather than a generic curve.
• Wide sample rate support: The UMIK-2 records from 44.1 to 192 kHz, allowing high-resolution capture for detailed acoustic analysis and advanced measurement routines.
• Low noise preamps and ADC: The combination of low-noise capsule and A/D convertor yields a clean signal floor, improving the accuracy of room and speaker measurements.
• Cross-platform plug and play: Native operation on macOS, Linux, iOS and Android plus an ASIO driver for Windows simplifies setup across systems without extra hardware.
• Compatibility with measurement software: Works directly with Room EQ Wizard and Dirac Live (v3+) as well as many other measurement and DSP platforms for immediate integration into a tuning workflow.
• Included accessories: The package includes a mini tripod, mic clamp, wind screen and USB cable so it is ready for most measurement setups out of the box.

Who It's For

The UMIK-2 suits audio technicians, speaker designers, and serious home audio hobbyists who perform objective measurements and value repeatable data. Its calibration file and low-noise front end make it useful for room correction, speaker response plots, and multi-channel/surround measurements where accuracy matters.

This microphone is not aimed at casual content creators looking for a colorful vocal mic or those who need on-stage performance gear; it is a precision measurement tool rather than a production condenser mic for artistic recording. Users who require extreme portability without a calibration workflow may prefer simpler USB mics, but anyone needing trustworthy measurement data will appreciate the UMIK-2.

Pros & Cons

Pros

• Per-unit calibration file provides reliable, repeatable frequency measurements for room and speaker tuning.
• Driverless operation on macOS, Linux, iOS and Android reduces setup friction for many systems.
• Low-noise capsule and quality A/D give a clean measurement signal and wide usable dynamic range.
• Includes tripod, clamp, wind screen and cable so the mic is ready for measurement work immediately.

Cons

• Not designed as a tonal microphone for music production; some users note subjective differences in sound quality when used outside measurement contexts.
• Windows users need to install the supplied ASIO driver for full compatibility, adding a small setup step.
