Procedural Audio

Procedural audio is sound generated at runtime from algorithms and models rather than from the playback of pre recorded files.^[1] A procedural model of a sound, such as an engine, wind, or impact, can respond continuously to parameters like speed or force, producing output that matches the situation exactly.

This offers variation and tight interactivity that fixed samples cannot, and it can reduce memory use because sounds are computed instead of stored. The trade off is computational cost and the design effort required to build models that sound convincing across the full range of inputs.^[2]
