Sound Design

Sound design is where physics, perception, and taste meet. These articles work through the actual mechanisms, how granular engines slice and reassemble time, why modal resonators can imitate a struck bell, what spectral processing really does to a signal, so you can build a sound deliberately instead of turning knobs until something works.
