What is the function of sound design in post-production?

Sound design in post-production plays a crucial role in enhancing the overall viewing experience by adding appropriate sounds that complement the visuals. This involves selecting and mixing sound effects, dialogue, and ambient sounds to create an immersive audio landscape that supports the narrative and emotional tone of the film or video.

In contrast, recording dialogues on set pertains to production rather than post-production, as that work is performed during the filming phase. Planning cinematography involves the visual aspects of filming, such as shot composition and camera movement, and does not directly relate to sound design. Creating marketing materials, while important in the overall scope of a film or video project, falls outside the realm of sound design, which specifically focuses on audio elements. Therefore, enhancing the visuals with appropriate sounds in post-production is a fundamental and defining function of sound design.
