Gas Flame Hiss

How it's made

Source

steady premixed gas jets entrain air at burner ports; independent white and pink turbulence form a smooth hiss, high-passed at 650-1550 Hz and double low-passed at 3.4-7.6 kHz.

Body

diffuse combustion noise at 240-2100 Hz fills beneath the jet hiss, with broad Q 0.55 colouring around 650-1350 Hz; no discrete cavity tone, oscillator, crackle or ignition event is present.

Layers

a faint independent pink-noise pressure bed at 55-240 Hz adds burner rumble below the hiss.

Envelope

continuous sustain for an 8 s loop; the renderer crossfades the seam, without ignition fades.

Modulation

0.45 Hz random pressure drift changes gain by at most 3.5 percent; 1.3 Hz mixing drift shifts the hiss cutoff by at most 3 percent. The level remains steady rather than gusting or pulsing.

Variation

named random streams separate each noise layer and modulator; jet opening controls colour, burner body controls low combustion weight, and stereo spread represents the width of the port ring.

Presets

low simmer is soft and narrow; domestic burner is balanced; camping jet is bright and compact; wide ring is darker, broader and has more low combustion body. All are dry, stable blue flames.
