It kind of does. All audio sent over FM is modulated to fit within the data band it can handle.
>The full audio spectrum ranges form 20 to 20,000 Hz, but FM radio limits the upper modulating frequency to 15 kHz (cf. AM radio which limits the upper frequency to 5 kHz). Although, some of the signal may be lost above 15 kHz, most people can’t hear it anyway, so there is little loss of fidelity.

But it’s not the radio waves that affect the sound, it’s their ability to carry information that affects it.
