What is NAT sound primarily used for in video production?

NAT sound, short for natural sound, plays a crucial role in video production as it captures the authentic audio environment of a scene. This includes ambient sounds like the rustling of leaves, distant conversations, or the sounds of a bustling city. By incorporating NAT sound, filmmakers create a sense of realism and immersion, allowing viewers to feel as if they are present in the setting. This type of sound enhances the overall atmosphere, enriching the storytelling experience by providing context and depth to the visual elements.

While improving dialogue clarity, amplifying background noises, or eliminating unwanted sounds are important aspects of audio production, they do not define the primary purpose of NAT sound. Its focus is on embedding the natural sounds of the environment to enhance ambience, making option B the most accurate choice.
