Spectrum Analyzer RTA

No longer works with latest IOS 14

It has come in very handy for debugging switched mode power supply designs to track down audible buzzing etc. Only suggestions are: 1) screenshot button 2) ability to save to csv data file for use in MATLAB etc. 3) is there a way to use some kind of broad spectrum USB microphone?

Since an ios update the screen of my ipad strobes when i run this app. Shame because the app is the best of its kind otherwise.

It's a useful app, but would be so much better if it could analyze the tunes in your music library (i.e open & playback a song)

I can’t upload anything in the mic section. How do you upload a file when it doesn’t let you? I click on it and it just exits out of the mic screen. Please fix.

Bought this to measure a high-frequency hum which disappeared when I bought the app. So thanks for that. Seriously, though, a very nice UI wrapper around the FFT.

i’m very pleased by this Spectrum Analyzer; it is the only one that I’ve found that can run at full speed on an iPad Air 2! A+ To the devs; if you’re still updating this app, i’d appreciate a way to select other inputs on audio interfaces; I’d love the ability to monitor what’s coming into inputs 3+4.

I have used this app for many many years and made lots of money fixing sound issues. Also, the Spectrograph at max sensitivity can find any power whine to help regain your sanity. 10/10

Love this app, and the customer service is top notch 👍

Faber tried to rip me off by bricking my app with IOS 13 I refused to buy into their greed and purchased this app glad IO did it works really well Good App
