***** "As a former IEEE Technical Committee Chair for Signal Processing, I find this app amazingly flexible and useful. Works very well with its proper designed-in control selections." - Roblake Spectrum Analyzer for iOS is a powerful real-time audio analysis app. Designed with musicians and recording engineers in mind, it can also be used by anyone interested in the world of sound. Ideal for room tuning or speaker tuning, the app enables portable, precision audio measurement and visualization. Feature Highlights: ● Octave Band Real Time Analyzer ● FFT Plot (Fast Fourier Transform) ● Spectrograph module ● Test Tone and White/Pink Noise Generator ● Native iPhone X graphics >>> Check out the demo videos at SpectrumAnalyzerApp.com Audio input may be acquired via the built-in microphone or an external measurement microphone. For best results we recommend using a calibrated measurement microphone connected via USB audio interface or iPhone dock connector. This allows for high precision and flat frequency response, as well as for stereo input.

How to upload mic cal file?
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.
United StatesVisually beautiful, and exactly what I expected technically
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.
United StatesBest RTA on the App Store, PLEASE UPDATE!
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.
United StatesAbsolute perfection
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
United StatesCool App!
Love this app, and the customer service is top notch 👍
United StatesNew App
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
United StatesFast and Easy
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
