Description

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.

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.

Developers have removed key functionality

I purchased this years ago because it would display the electronic resonance carrier waves emitted by powerful RF emissions, like cell phone towers. Now, over the past year or so, the developers have deliberately removed these background resonance waves from being displayed; I can only guess why.

I have emailed them twice with no response. I’m pretty sure they know what they did, and why.
