frequency detection (DTMF)

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.
