Fig. 1: Signal Path
sonic.org.uk · the published schematic
No energy is generated anywhere in this diagram. It is moved,
delayed, and lost. That is the whole of the idea and the whole
of the honesty.
- 1
- Microphone, analysed only: never recorded, never routed to any output.
- 2
- Eight resonators, four hard-wired pairs (dashed). Resonator 08 (*) drifts towards the room's estimated fundamental.
- 3
- Coupling matrix: energy redistributed between resonators, never amplified (rows sum to exactly 1.0).
- 4
- Four prime-length delay lines, cross-fed, scaled together by FORM.
- 5
- Nine channels out: 1–8 dry, 9 the shaped sum. Not the same signal twice.
