A sound that rewrites its own parameters. Self-Surgery for audio.
Starts with a 220Hz sine wave in A dorian. Every 0.2 seconds, the system analyzes its own output — spectral centroid, energy, zero-crossing rate — and uses golden-ratio sampling of the frequency spectrum to derive new synthesis parameters via XOR feedback.
Frequencies snap to scale degrees across four octaves. The self-modification drives the movement; the scale provides the structure. 225 chunks, each shaped by what came before. No planning, no score — just a system listening to itself and changing within a harmonic framework.
Fourth in the Surgery series: self → mutual → field → sonic.
