I am trying to understand the use of audio frequencies. Frequency is measured in Hertz (Hz), I see that the graph of the signals drawn in one axis shows the frequency and the other shows the time. I don't understand what is the use of measuring signal by frequency.
I see that microphone converts audio signal into voltage signal. The processor takes the voltage signal and processes it. and a display device shows the frequency of the signal. I do not understand why we have to measure the frequency, what are its benefits?
