"WebDTMF (Dual tone multi frequency) as the name suggests uses a combination of two sine wave tones to represent a key. These tones are called row and column frequencies as they correspond to the layout of a telephone keypad. A DTMF keypad (generator or encoder) generates a sinusoidal tone which is mixture of the row and column frequencies. " - Dtmf arduino project
