AudioFrog announced a new USB microphone kit for calibrating car audio systems.
The UM-1 is an omni-directional microphone that works with a PC-based RTA program. You also get a mic stand and sound card at $199. It’s compatible with Macs and tablets as well as PCs. Shipping is expected in May.
The UMI-1 may be used with most acoustic measurement and analysis software including Room EQ Wizard (REW), True RTA, Holm Impulse, ARTA and others.
The adjustable microphone stand is designed to mount easily to the car’s headrest using a Velcro strap to place the microphone in the ideal location for real time frequency response measurement and analysis. The calibrated microphone provides response from 20 Hz to 20 kHz.
A separate calibration file for each serialized microphone is available from Audiofrog.
UMI-1 Kit Includes:
6 mm Omnidirectional Measurement Microphone with Calibration File
USB Sound Card with Mic Input and Stereo Line Output
Microphone Stand with Integrated Extension Cable
Velcro Headrest Strap
Extension Cable
3.5mm Stereo to RCA Adapter
3.5mm Male to Male Adapter
Test CD
Carrying Case
Cheap, I thought it was going to be $1900
Are you kidding me? We’ve been doing this for pennies for a several years now. You can buy a microphone exactly like that for 20 bucks, that’s a (poorly) 3D printed microphone stand, and software you can get for free from to iOS and Google Play Store.
