Screenshots

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.

    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. Show more

    Meh
    It’s pretty good. It has a fast output, it reads sounds almost immediately. But there’s no playback and isolation option. I feel like that should be a basic feature in a pro version. Show more

    Versatile real-time spectrogram
    It is fast, with easy-to-read and adjustable scales, colors and gain. I also like the frequency cursors!

    Great for finding frequencies
    If you want to know if a high pitch squeal is coming from a device, this app is great for sniffing it out. Really fast update rate and UI response. Log vs linear is great for really dialing in higher or lower frequencies. Show more

    RPO
    Programmers took away the 16-20kHz frequencies. Can no longer see the Easter eggs in movies.

    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. Show more

    KILLER APP
    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.

    Best app
    Pinpointed exactly what I was I looking for in seconds

    No IAA / AudioBus support
    One of the nicest looking spectrograms around, unfortunately it only supports mic input. Does not work with AudioBus or AUM.
