Physical modeling

Physical modeling is a sound synthesis method that simulates the real-world physical behavior of an instrument(strings, wood, metal, air, etc.) using mathematical equations. Instead of relying on samples or traditional waveforms, it recreates sound by modeling physical interactions—like string vibration, tube resonance, or air pressure. This technique allows for highly expressive, dynamic, and realistic sounds, while being lightweight in terms of memory. It’s used in advanced synths like SWAM, AAS Chromaphone, or the Arturia Physical Modeling Suite.
