Spectrogram Pro does a real-time spectral analysis of the sounds around you. You can use it for discovering hidden images in music, analyzing birdsongs or capturing that annoying high frequency whistling of your electronic device.
You can choose between four FFT-resolutions, logarithmic or linear fequency and amplitude scale and four color-schemes and adjust the sensitivity. Also you can share and save the spectrogram-images. There are also bode plot-modes with averaging and maximum-calculation. The spectrogram is updated with 60Hz for a super-smooth and comfortable experience.
-compatible with most recent iOS versions and devices

No IAA / AudioBus support
One of the nicest looking spectrograms around, unfortunately it only supports mic input. Does not work with AudioBus or AUM.
Dangerous to leave open
This app isn’t bad. I use it every day. But it lacks some spit-n-polish that a “pro” app should have. For example you get one - ONE - guideline. You cannot demarcate a range, you can only target one single frequency.
The most glaring problem though, is if you leave it running in the background, even in paused mode, it will ravage your battery. An iPad Pro that normally lasts weeks on a charge is completely discharged within 3 hours even though the app was in the background and the iPad put to sleep. SO BE CAREFUL!
The last update was a year ago, so this is likely as good as it gets.
I don’t know Bode from booty, but this is the most perfect frequency app for anyone, musician or not, to explore the world around them. Buy now.
With Family Sharing set up, up to six family members can use this app.
