Modulation sound effects follow signals that keep changing as they play. Radio interference and static, oscillations from subtle to complex, beeps and transmissions from an old sci-fi computer, and a toy drone with its motor modulating as it flies. Very little holds still. Dark drones and electronic noise sit alongside, for a bed that moves under a scene rather than sitting flat.

Modulation means a sound changing over time, its level or frequency pushed around by something else. In radio it's also how a voice rides a carrier wave, which is why so many of these recordings come off the airwaves: Interference and Morse Code, next to sonar pings. The rest is designed. Oscillations and dark drones give a sci-fi corridor or a control room a moving bed, and the toy drone adds real motor modulation with servo textures on top. They suit sci-fi games and anything set in a radio room.
