Simulating how sound bounces off walls, floors, and ceilings to make every room feel real to your ears.
In the real world, sound doesn't just travel from source to ear -- it bounces off every surface in between, creating reflections, echoes, and reverb tails that tell your brain the size and material of the space you're in. Game audio engineers simulate this using reverb algorithms and impulse responses. A cathedral sounds massive and echoey, a closet sounds tight and muffled, an open field has almost no reverb at all. Modern systems like ray-traced audio actually cast sound rays into the environment geometry to calculate acoustics in real time, rather than relying on hand-placed reverb zones.
Example
In Battlefield 1, firing a rifle inside a stone building produces a sharp, ringing reverb that vanishes the moment you step outside. Rainbow Six Siege calculates sound propagation through rooms and corridors, so you can tell from the reverb alone whether a gunshot came from the floor above or the room next door.
Why it matters
Reverb is the subconscious cue that tells your brain whether a virtual space is real or fake. Get it right and players feel physically present. Get it wrong and the entire soundscape feels like a flat recording pasted on top of a 3D world.
