How it's made
- Ignition
- a soft gas "fwump" at the start, brown noise low-passed to ~220 Hz with a 15 ms attack and a ~140 ms decay, plus a short bright flash of pink noise as the flames catch.
- Whoosh
- the ball rushing past, pink noise through a band-pass whose centre climbs from ~300 Hz to a few kHz as it nears and falls away after the peak (Doppler-like brightness), travelling across the stereo field.
- Roar
- burning gas, brown noise below ~450 Hz, amplitude-modulated by a fast drift (turbulent flutter) and swelling with the whoosh, then dying with the flight.
- Crackling trail
- sparks and burning fibres shed behind the ball: sparse high-passed unipolar impulses plus Poisson wood-resonance crackles, dense right after the cast and thinning out as the fire flies away.
- Envelope
- sharp onset (about 15 ms), the energy peaks at ~35 % of the length, a long fading tail.
- Variation
- peak time, crackle tuning, level and pan come from `rng`; presets change size, speed and heat.

| brightness | 0 – 1 | 0.5 | — | Brightness |
| crackle | 0 – 1 | 0.6 | — | Crackle trail |
| travel | -1 – 1 | 0.7 | — | Negative values fly from right to left |
| seed | int | 1 | — | Variation, reproducible |
