Ratings and reviews

Out of all the RTA (well not really but) apps available this is the only one that can come close to displaying what is being played but the levels needed to calibrate speakers is far beyond any phone mic's capabilities. It's just recording distortion + limited frequency response at high and low extremes make these apps worthless for any real use in the audio world. Others can't plot points even close to a real RTA at any level. None can be used for the intended purpose your results will be awful

Somehow I became a beta tester. I don't mind, but? Well I bought the original RTA, now it's the beta RTA. I don't understand. When I click on your website it's gone. Even the pro beta version suggests I get your noise generator, which only works with Android9 and under. If only there was a way to use an external mic for calibration and use! Hey guess what, 13 almost here. So there's your beta testing for you lose the suggestion to download your NG ! Option two make NG compatible with 9 and up !

This apps ok great for RTA analyzer..the only thing that i think is this apps will better if we can load the calibration file for the calibrated microphone.
