About this app

This program turns your device into a simple oscilloscope function of the spectrum analyzer, signal source is the microphone input of your device. With this program you will be able to compare the level of noise (sound) in different areas or from different sources, as well as to determine the spectrum of audio signals. You can take a picture signal by moving the program mode pause and examine in greater detail the form and spectrum of individual sections of the signal.
The spectrum of the signal is determined using FFT.

Ratings and reviews

Wow, I've tried almost 10 similar alternatives but this was the only usable app. Simple interface, few but very usable features. Exactly what's needed. And, it has a small installation footprint and no dodgy requests for unnecessary permissions. Top marks for the developer! 😀

Good app but could do with some improvements. Adding a audio wave detector would be very nice along with a proper funtion generator going to 5ghz. I have another app which does this but it is not so feature rich and I would like it to be added.

Perfect. Allows you to measure the periodicity of a sound signal like an electronics oscilloscope. Most other apps are just toys for a nice UI. This is useful.
