Sound design is the art and practice of creating soundtracks for a variety of needs, including film, television, theater, and video games. It involves the manipulation of audio elements to enhance the storytelling experience, using techniques such as Foley and sound effects to create an immersive environment. In sound design, professionals work with both recorded sounds and synthesized audio to craft a unique auditory experience. This can include everything from the subtle rustle of leaves to the dramatic roar of an explosion, all aimed at evoking emotions and enhancing the narrative of the visual medium.
