## What is Spectrogram Pro (with super?

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.

## Key features

- Real-time spectral analysis
- Adjustable FFT resolution
- Logarithmic/linear frequency and amplitude scales
- Multiple color schemes
- Adjustable sensitivity
- Save and share spectrogram images
- Bode plot modes with averaging

### 1/5 — No ability to load an audio file?

*2025-06-07*

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.

### 2/5 — No way to zoom in?

*2023-07-31*

Useless to me if i can’t zoom in or in other words restrict the frequency range that it covers

### 1/5 — Developers have removed key functionality

*2021-04-16*

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.

### 4/5 — 截屏功能不好用 但整体OK

*2021-04-05*

打开新世界 做的很棒 谢谢开发者！

### 2/5 — Meh

*2020-12-27*

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.

### 5/5 — Excellent rta

*2020-11-20*

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

### 5/5 — Versatile real-time spectrogram

*2020-10-17*

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

### 5/5 — Perfect.

*2020-10-13*

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!
:)

### 5/5 — Great for finding frequencies

*2019-08-29*

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.

### 3/5 — Works well but limited by lack of frequency scale

*2019-08-07*

The app works fine and the options are good, with one major exception. Not being able to set the limits of the frequency scale renders it unusable on a small screen for some tasks.
