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.}

Buyer beware. Unless I’m missing something, there is no ability to load an audio file into this app, as quality of the demo seems to imply. This should be a basic function at this price.

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.

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.

Excellent program, up until ios14.2. Unfortunately the app crashes apron loading on my iPhone XS Max. It’s useless now. Don’t update to 14.2 if you want to use this app

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

Exactly what I've been looking for. You would not believe the number of apps I've scrolled through and looked at before I found this. I wanted a simple, clear, waterfall display type of spectograph that would give a visible record of the frequency and duration of certain transient sounds. There are apps out there that have this, but the ones I found were expensive, most requiring a monthly subscription or very high one off payment. This is just what I need & at a great price. I love the frequency measurement you can access by touching the sound trace, it helps enormously if I want to tune a notch or band pass filter in order to isolate a sound. many thanks, great app! :)
