How it's made
- Source
- an electrically driven energy field. Its hum is a stack of detuned saw and square partials at ~180 Hz with a fast amplitude flutter; overload adds a stuttering burst of arcing, i.e. sparse unipolar crackle impulses plus gated band-passed noise.
- Body
- as the field loses power the hum pitch falls exponentially (to ~21 % of its start) while a low-pass closes from ~3 kHz to 250 Hz, so harmonics vanish first; a short sine thump (110 → 40 Hz) marks the collapse.
- Envelope
- the hum starts at full level, wobbles with a flutter that slows from 38 Hz to 6 Hz and fades out by ~75 % of the length. Crackle density is highest in the first quarter and then thins out exponentially.
- Fizzle
- after the hum is gone, 3–8 kHz sparks pop at a falling rate, each a short ping, giving the fizzling tail.
- Variation
- `rng` shifts the hum detune, crackle timing and flutter phase; `length` stretches all envelopes, `pitch` scales the hum, `crackle` sets arcing density, `brightness` the spark and filter colour.
