Burning Torch

How it's made

Source

burning fuel on a wrapped torch; continuous turbulent pink noise, with brown-noise heat roar.

Body

broad, non-ringing bands at 70–420 Hz and 250–3000 Hz describe a small open flame, not a cavity. Escaping hot gas adds a subdued 2–6 kHz hiss; a 7 kHz low-pass prevents brittle ultrasonic fizz.

Envelope

the bed stays alight throughout an 8 s seamless loop, breathing at 0.7 targets/s by 12 percent. Random 0.18–0.46 s flame folds occur 0.35–1.6 times/s, with 25–60 ms attacks and rounded decays.

Modulation

each fold increases 5–11 targets/s irregular flutter and raises the flame band's cutoff; there is no periodic tremolo. The engine crossfades the loop boundary into following generated audio.

Events

fuel fibres rupture 0.4–3.6 times/s as 1–3 ms attacks and 7–20 ms filtered noise tails. They remain subordinate to the continuous flame; no log-sized pops or long pitched resonances.

Variation

seeded streams vary turbulence, fold timing, burst colour and strength independently. Presets cover a small wick, sheltered wall torch, resin-rich flame and a torch exposed to moving air.

Space

dry, compact mono point source; scene placement and room acoustics belong to the user.
