SpectrumAnalyzer has a very simple interface consisting primarily of an onscreen ON/OFF switch. The normal output is a display of the Fourier spectrum of the audio picked up by the microphone. No advertisements.
There are a few options available via the Android Menu key. The user may toggle to switch between a white or black background. The user may also view the actual sound waves directly (as opposed to viewing their frequency spectrum).
The duration of the sound snippet is 0.1 second.
I have noticed that there are two lines at 7,200 and 14,400 Hertz while developing Spectrum Analyzer. I suspect these sounds are emitted from the hard disk that runs at 7200 RPM. Outside, I noticed crickets chirping around 5,600 Hertz.

The program uses the new Google licensing standard. In theory this means the program can be copied to an SD card, freeing up internal memory in the Android, although I haven’t tried it.
If you have purchased the software and need help or would like to discuss your application, I will be happy to spend a few minutes with you on the phone (321.252.8205).
