How do I calibrate my UMIK-1 file?
Unique Calibration File Download All UMIK-1 are calibrated with a unique calibration file. In addition, a unique auto-generated 90-degree calibration file for use with surround system applications. To download the calibration files, look for the 7 digit Serial Number found on the body of the microphone.
How do you use Rew and UMIK?

Is the UMIK 2 worth it?
“The UMIK-2 is a substantial 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 converter) built into the microphone shell.
What does a calibration microphone do?
Laboratory standard microphones calibrated using this method are used in-turn to calibrate other microphones using comparison calibration techniques (‘secondary calibration’), referencing the output of the ‘test’ microphone against that of the reference laboratory standard microphone.
How much does a smoothing Rew cost?
What I do, and what I believe is the accepted norm in the REW threads, is to use no smoothing on sub frequency graphs and anywhere from 1/24 to 1/6 smoothing on full range graphs.
Where should I calibrate my microphone?
The mic should always be placed at a seated listener’s ear height and facing the ceiling; it’s calibrated to work best that way. The ideal way to position the mic is to place it on a camera tripod. Start in the center position and then move 2 feet to the left of it and then 2 feet to the right.
What is Erb smoothing?
ERB smoothing uses a variable smoothing bandwidth that corresponds to the ear’s Equivalent Rectangular Bandwidth, which is (107.77f + 24.673) Hz, where f is in kHz.
What is EQ Wizard?
Room EQ Wizard (REW) is free room acoustics software for measuring and analyzing room and loudspeaker responses. The analysis helps you optimize your studio by finding the best spot for the speakers and listening position. Shooting the room gives you a thorough understanding of how frequencies behave in your space.
What does a good frequency response curve look like?
The frequency response curve (so-called because a speaker’s or headphone’s frequency response will curve, or roll off, in the low bass and high treble) is pretty flat (“flat” is good, because it means the device is accurate), with no serious peaks, dips or other up-and-down variations.
How do you EQ in Rew?
On the main REW screen, select the average measurement in the list of measurements at the left. Then click on the “EQ” button.
Can you use any calibration microphone?
You have to use a mic that is made for your receivers calibration system. It will work across models just fine, but the exact quality of each mic is pretty hit or miss as they are pretty cheap mics. You want to use the one that came with your receiver as that mic is calibrated for it.
What is ERB scale?
ERB-rate scale The ERB-rate scale, or ERB-number scale, can be defined as a function ERBS(f) which returns the number of equivalent rectangular bandwidths below the given frequency f. The units of the ERB-number scale are Cams.
Is the Umik calibrated for accuracy?
Each UMIK is individually calibrated for accuracy. In this application note, we’ll show you how to get up and running with the UMIK-1 or UMIK-2.
How do I calibrate my umik-1 preamp?
Connect the RCA plugs to your preamp. For connection to an A/V receiver or processor over HDMI, see the app notes on using a UMIK-1 or UMIK-2 and REW with HDMI output on Windows or Mac. 2. Get your calibration files [Top]
How do I make measurements with the umik-1?
To make measurements, you will need to: Get audio out from your computer into your stereo or home theater system. If your computer has a USB Type-A port, connect the UMIK-1 (original) to your computer using the supplied USB Type-A to Mini-B cable:
How do I change the sample rate on my Umik?
Open the Audio MIDI Setup application. Click on the output device and drop down the menu to set its sample rate. If you are using a UMIK-2, click on it and drop down the menu to set its sample rate. (The UMIK-1 can only operate at 48 kHz.)
