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.
