Film sound design is the art and practice of creating the auditory elements of a film. This includes dialogue, sound effects, and background noise, all of which enhance the storytelling and emotional impact of the movie. Sound designers work closely with directors and editors to ensure that the audio complements the visuals and helps convey the intended mood. In addition to creating new sounds, sound designers also use foley techniques, which involve recording everyday sounds to match the actions on screen. They may also manipulate existing audio through editing and mixing to achieve the desired effect, making sound design a crucial aspect of the filmmaking process.
