How it's made
- Source
- an electromagnetic panel buzzer driven by a band-limited 140–360 Hz square wave. A weak second harmonic and 45 Hz amplitude ripple represent asymmetric diaphragm motion.
- Body
- a broad diaphragm resonance at 3.2 times the drive pitch adds nasal bite; a 1.4–4.8 kHz low-pass bounds the rasp. Filtered contact noise and a 640 Hz panel mode add mechanical grain.
- Envelope
- 2–8 pulses per two-second cycle, 38–82 percent on-time, 5 ms attack and 14 ms release. Pitch settles down 1.2 percent in 35 ms; brightness relaxes over 65 ms as the coil loads.
- Layers
- the drive dominates, the resonant branch is 22 percent, and contact noise is at most 7 percent; the panel's 45 ms ring follows a quiet 6 ms contact excitation. Dry centred output.
- Variation
- seeded component tolerance shifts tuning by at most 0.2 percent per build. Presets change pulse count, duty, pitch, spectral bite and contact grain for four panel roles.
- Loop
- integer pulse counts align to two seconds; every pulse and panel ring ends before the next.
