Works well with REW.

Got my entire stereo system installed in the car, was super excited to Tune it with REW. The unit I received lights up Blue, but there is zero input picked up. I have tried multiple PC's, MAC etc. As someone else said, how did this thing get a calibration file if its already dead when it made it to me.

This is a pretty good microphone to use for home or vehicle. The only downfall is the size of the microphone and the calibration file from Dayton doesnt work on SMAART unless you alter their calibration file. I setup (FS -20 94db) and compared it to one of my ISemCon microphone with 85db, pink noise, and it came relatively close. Then I created a calibration file myself using my ISemCon as reference. It's definitely worth it, if you are using it for home or car. I wouldn't use this on the field to calibrate a large room, I'd probably use it only for SPLs and to keep RTA running at Front of House. 4/5 score mainly for the size of the microphone. Performance is great

Used to tune the audio in my car, I'm very happy with the results. Build quality and materials are also excellent. Seems to be solid aluminium.

Worked well with pink noise audio adjustment

The mic. works just as promised. The software is like a 3-credit course. Be prepared.

Great mic to tune your audio system

Detected by Windows an the blue LED lights up. But receives no sound whatsoever despite 100 input level. Tested on multiple devices.

Worked perfect to calibrate my Helix DSP.2

it fully met my expectation. the delivery timeline was also perfect.

Good cal file . Works very well
