Description
This is just a little demonstration on how to do frequency detection on digital audio signals.
You can generate a signal from a DTMF sign (numbers, chars), which consists of 2 frequencies,
and the program will detect it by using a Görtzel algorithm.
Frequencies + Detection musn't always mean FFT.
Sometimes there are faster ways.
