Spectrum Analyzer RTA

Full features and very responsive Octave RTA, which accepts both uncalibrated and calibrated microphones like iDSP ones. Has a full FFT plot as well. Spectrograph is really useful to identify sources of that annoying pitch you can hear among all the noise. Perfectly fluent user interface, simple yet fully functional. No delays, no glitches, the spectrum just comes alive on the screen. I can not describe how fluid the user interface feels - you just have to try. This is truly impressive! Check out their web site for a neat tutorial on how to EQ a room!

Great app, also accepts calibrated microphones and their cal files.

Simple but effective RTA app.

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

Simple instructions, easy to use on my iPhone 6. Just make sure the mic port is not obstructed...or better yet, buy a Dayton Audio iMM-6 ref. mic from Amazon $15 becaus it has better low end response
