What is the difference between production sound and post-production audio?

• A. Production sound is captured on set; post-production audio is edited, enhanced, and sometimes created in the studio.
• B. A single bus with both dialogue and music sharing processing.
• C. Production is for music, post for dialogue.
• D. Production refers to video; post refers to color grading.

Answer: (A)

The concept here is separating what happens with sound during the shoot from what happens after the shoot. Production sound is captured on set during filming by the production sound team. It covers dialogue and on-site ambience and is influenced by the environment, mic placement, and practical noise. The aim is to get usable, clean dialogue and natural room tones that fit the scene as it was captured.

Post-production audio refers to everything done after filming. It involves editing what was captured, cleaning up imperfections, and enhancing it in a studio. It also includes additional elements like ADR (re-recorded dialogue), Foley (everyday sound effects), sound design for effects, and the final mix with music. In short, production sound is what you record on set; post-production audio is how you refine, replace, and add to that sound in the studio to create the final soundtrack.

Why the other options don’t fit: describing a single bus that shares processing oversimplifies how professional audio is organized, with dialogue, music, and effects often kept as separate tracks. Saying production is for music and post for dialogue reverses their typical roles, and confusing production with video tasks like color grading mixes audio with video roles in a way that isn’t accurate.
