RTA Pro Analyzer

1. Why doesn't this app have weighting options in the measurement settings? All Pro RTAs have it. It would have been nice to have a A weighted and C weighted measuring profiles. 2. Also how to calibrate it is not clearly mentioned. I have excellent pink noise in my studio. Would like to calibrate it on my phone as closely to a standard RTA as possible. Any help would be greatly appreciated. Thanks.

To those who get crashing when calibrating here's the fix. Before clicking on continue to start calibration, make sure u are in a dead quiet environment. Then give it at least 15 seconds for bars to lower. Then turn up your pink noise. It should work fine then.

Works well. Has the basic FFT functions, but doesn't include signal generation. My only beefs are that the peak hold line is so thin that it's nearly invisible; there's only a bar display mode, no line mode; and no way to load a mic cal on top of the internal circuitry cal.
