Audio Spectrum Analyzer App Reviews

This is a great app for showing the basics of FFT to physics students. It would be a nice touch to add the ability to manually place markers, but with care the auto-peaking markers work well enough. Not bad for a few measles bucks!

Very east to use. It allows stretching/shrinking the frequency axis (for the linear scale only). It would be nice to have a way to freeze the spectrum to make some quantitative comparisons. Then a screen snapshot could preserve the results. Would also like to know just what kind of filtering is being used.

This works really well for audio analysis

Happy with this app. Frequency markers on peaks very handy. Checked against 500 and 600 Hz tones on WWV and both were within 0.1 Hz. Recommended.

I bought this app because I wanted to identify a mysterious high-pitched tone that was audible in my house. It worked great. The tone was clearly visible as a peak around 6400 Hz, and then I was able to confirm using a tone generator. Im just a casual user, but the app presents a feature set that would appear to satisfy more serious users too. It also has a very no-nonsense interface, which is what I look for in an app.

Last one youll have to buy. Make an apple watch port please!!

Exactly what I was looking for. Just right.

Nice analyzer and responds well. However some features would be nice.i would like to see the ability to freeze a spectrum and possibly save it or have it emailed so it could be studied. Also, it would be nice to isolate portions of the spectrum to analyze it.

When I want to the frequency of a background tone on the radio, this works great. My wife bought some Tibet bowls. I wanted to know the resonant frequency for each bowl. This app worked great. Lots of applications. Now, only if it could fix the ringing in my ears!

I monitor a bluegrass band with this app. Nice to know room characteristics for PA low & high freq. settings.

This app offers nothing that you could not get from a free spectrum analyzer app. In fact, you will find it more convenient to work with many of the free apps. This app has absolutely no features that could justify paying for it. All it does is doing a simple FFT. I want my money back, however it is too late - unfortunately!
