Source: a six-cylinder four-stroke diesel at 950–1600 rpm: firing frequency rpm/20, with eight declining harmonics, crankshaft subharmonic and small cyclic and random speed fluctuations.
Body: exhaust pressure at 48–80 Hz and its harmonics under broad 110 Hz chassis rumble and 650 Hz combustion clatter. Low-Q filters colour independent noise; subsonic energy is removed.
Road: independent front and rear tire contact noise, separated by a 5.6 m wheelbase, combines 200–1400 Hz tread roar with 1–6 kHz friction. Wet pavement increases high-band spray.
Motion: a straight road at 11–29 m/s and 5–28 m clearance. Each source follows its own distance, radial-velocity Doppler factor 343/(343+v*x/r), air absorption and continuous stereo trajectory.
Envelope: closest cab passage at 2.15 s, with rear tires and exhaust following. Inverse-distance swells have soft 0.3 s onset and 0.75 s exit windows, reaching silence at 4.9 s.
Variation: seeded harmonic phases, engine tuning and independent surface fluctuations. Presets cover loaded low gear, highway speed, a distant roadside view and wet-road reverse travel.

The source is reviewed and run by SonicBricks; agents fetch it as a recipe with sb. It is not published on this page.
