Most Frequency Modulation(FM) radios submit subcarriers on the carrier, like the audio signal but they are in a frequency range too high to be heard by humans. These kind of subcarries are are used to carry useful information and musicbeing transmitted onto the main carrier. FM radios depend heavily on the subcarrier to make a steriophonic effect. Frequency modulation is the frequency aspect modulated not the amplitude. The main audio is monophonic. Monophonic stops at a frequency of 18 Hertz.
