Factory Floor

How it's made

Source

a hall of machines. Hydraulic presses drop a die onto sheet steel on a fixed cycle (1–2.5 s), a belt conveyor runs continuously, compressed air vents in bursts, and loose parts clank now and then.

Press

each stamp is a low impact thud (a 45–90 Hz sine falling in pitch under a 30–200 Hz noise body, 120 ms) plus the struck plate ringing in inharmonic steel modes (0.3–1.2 kHz, ~0.4 s); a die-closing click leads it by 2 ms.

Pneumatics

after the stamp the cylinder vents. Air escaping a valve is broadband turbulence centred at 4–7 kHz, an abrupt onset and a 0.3–0.5 s exponential fall; separate random vents add 0.15–0.6 s bursts.

Conveyor

a motor hum (saw at 55–110 Hz plus its 2nd harmonic, wobbling ±1 %), belt noise in the 700–2000 Hz band, and roller ticks at 5–7 per second that pick out the belt joints.

Room

brown-noise rumble under 250 Hz and a diffuse mid-band wash with a slow drift, decorrelated left/right, so the floor feels large; the `space` control darkens everything as if heard from a gallery or the next hall.

Variation

`rng` varies every stamp's strength, plate tuning, pan and vent timing; clank rate and size, press tempo, conveyor speed and hiss level are the macro parameters, presets move between a calm and a heavy plant.
