If lighting tells the audience where to look, sound tells the audience what to feel. Sound design is the most consequential technical layer in any show — and the one most often left until last.
The Three Sound Layers
Score — the music itself, live or recorded. SFX — effects, transitions, environmental textures. Diegetic sound — sounds the characters can also hear (a door, a phone, a heartbeat). Each layer needs its own design.
The Spatial Layer for Immersive Shows
In immersive productions, audio must travel through the venue, not just from the stage. Distributed speaker arrays create the illusion of sound moving from room to room. Done well, the audience doesn’t notice the technology — they just experience the building as alive.
The Live vs Recorded Question
Live music wins emotionally every time. The cost differential is real but the audience response gap is bigger. For flagship galas, the answer is almost always live. For touring productions where consistency matters more than peaks, recorded with selective live overlay can work.
The Common Mistake
Sound mixed at the desk instead of in the room. Always mix from the audience’s seats. The room shape, the upholstery, the audience density — all change the mix in ways the desk position can’t predict.
The Pre-Show Test
Sound check with a full audience-density placeholder. Empty rooms sound different from full rooms by 6–8 dB of absorption.
The Producer’s Sign-Off
The producer should sit in three different seats during sound check — front, middle, back. If the mix doesn’t work in all three, the show won’t work in all three.
