This app in only available in the Google Play Store. If you are reading this on another site, do not download the app, it may be an old version, and is not authorized by me. Go to the Google Play please.
- In-app purchases: this permission allows users that want to support the future development and maintenance of this app to upgrade to PRO VERSION, paying a small fee, and without installing a new separate version. This process is the new trend in phone apps. This is a one time purchase only.
- Internet access: This is used only by Google Analytics module, so i can better understand what features are being used.
24 KHz is only possible in phones with a 48KHz sample rate DAC. Some very expensive phones do not have such a DAC. This is a hardware limitation.

The app plots the fundamental frequency versus time.
The application can be used to tune musicals instruments.
The app can be used to measure sound Doppler Effect: J.A Gómez-Tejedor, J.C Castro-Palacio y J. A. Monsoriu.

Display of triggered event count and frequency or time period.
Graph of input signal, 2.5 ms/div up to 640 ms/div.
Gate time of 0.1s, 1s, 10s or 100s.
Gain from x1 to x1000.
Trigger on rise or fall.
AC or DC coupling.
Set a noise level so new event is not triggered until the signal has first passed this level.
More details can be found on the website.
This real-time spectrum analyzer / audio visualizer features:
- 128 high-quality frequency bands [20Hz to 22kHz]
- Logarithmic frequency scale to match human perception
- Low latency for high responsiveness
- High framerate to see smooth frequency and amplitude movements
- High performance native code using OpenGL ES 2.0
- FFT window size 2048 @ 43/58(Armv7+) frames per second
The internet permissions are used for ads.
Any feedback is welcome.
Since v.1.0.7, you can choose FFT window size either 1024 or 2048. A higher window size gives more accurate frequencies but using a small window size is faster and recommended on low spec phone. You can choose two histogram plotting styles (area plot or bar graph) and see dominant frequency from the graph.
Hope you enjoy !
