Sound effects generated by code on the fly instead of playing back recorded files.
Instead of storing thousands of audio samples, procedural audio uses algorithms and physical models to synthesize sounds in real time. Wind, fire, rain, engine hums, and footsteps can all be generated mathematically based on game parameters. A car engine sound might be modeled from RPM, throttle position, and gear -- producing infinite natural variation. This approach saves memory, eliminates repetitive patterns, and allows sounds to respond to gameplay with zero latency. It's technically demanding but incredibly powerful when done right.
Example
No Man's Sky uses procedural audio for its vast universe -- planet atmospheres, creature calls, and ambient soundscapes are all algorithmically generated to match each world's unique properties. Gran Turismo 7 models its engine sounds from real physical data rather than simple recordings.
Why it matters
As games get larger and more dynamic, storing individual audio files for every possible scenario becomes impossible. Procedural audio is how games will scale sound design for infinite worlds and emergent situations.
