In audio, sound design is production design

In film and tv, production design is its own discipline. The credited head of department who builds the visual world of the story. Sets, locations, props, color, light, the lived-in feel of every frame. It’s the world the camera looks at.

In audio-only productions, the camera doesn’t exist. There is no frame. There is no visual world for a department to build. The world IS the sound.

Which means in radio, podcasts, and immersive audio-only productions, sound design isn’t just a post-production department. It IS the production design. The entire built world the listener inhabits, from the room a character is standing in to the weather outside the window to the distance between two people in a scene, exists only because someone designed it sonically. Capture choices and editorial choices and mix choices are all the same choice: what does the world feel like to be inside.

That reframes the role.

A sound designer who only knows post is an audio finisher on an audio-only project. A sound designer who only knows pre is a recordist. The work the medium actually demands is held by the practitioners who carry both ends in one head: how to plan a capture so the world is already half-built before edit begins, and how to shape the captured material so the other half lands. Pre-production and post-production aren’t a handoff in this medium. They’re one continuous design pass.

So the question for anyone commissioning an audio-only production isn’t “who’s editing or mixing this.” It’s “who’s designing the world.” Those are different questions, and on a visual production they have different answers. On an audio production they have the same one.

The people who can answer it are the people who’ve spent careers on both sides of the microphone, thinking about what the listener is going to inhabit before a single word is recorded and shaping it after every word is in.

That’s production design. It just happens to be made of sound.
