Matches our calibrated microphones.

I work in a Modal lab. I downloaded this app just for quick measurements on the fly, to verify my test setups. Works great. The FFT matches our $90,000 analyzes and calibrated microphones. I am impressed to say the least. Please update allowing for triggers.

This app works awesome. Only one upgrade I would suggest would be the ability to take screen shots and a record feature for data. I would still highly recommend.

Needs better programming. Needs averaging and slow response
