modulation
Carrier wave alteration
Modulation is the act of adjusting or varying something—typically tone, pitch, or intensity.
A speaker modulates their voice to convey emotion or emphasis: She modulated her tone to sound more reassuring.
In music, modulation is a shift from one key to another.
In electronics and broadcasting, modulation is the process of encoding information onto a carrier wave—amplitude modulation (AM) and frequency modulation (FM) are the classic radio technologies.
