How it's made
- Source
- rubber tires slowly shear and compress a gravel bed; filtered pink noise supports many overlapping 12-65 ms grain scrapes, with separate 2-8 ms stone collision excitations.
- Body
- loaded tire contact is a broad 65-320 Hz rumble; crushed grit occupies 600-6500 Hz. Loose stones have three inharmonic, heavily damped modes around 0.9-6 kHz, T60 18-55 ms.
- Envelope
- contact rises over 180 ms, swells again as the rear axle arrives around 1.25 s, then slows and unloads by 2.85 s; a 150 ms safety fade ends the dry event near 3 s.
- Events
- overlapping scrapes at 32-75/s follow contact pressure; larger stones pop at 4-15/s, with occasional quieter delayed bounces. Grain density and brightness fall during the stop.
- Variation
- seeded event timing, strength, size and narrow stereo position prevent repetition. Grain size sets spectral weight; load adds tire body; looseness adds displaced stones; pace controls micro-event rate. Presets span fine grit, loose coarse stone and packed gravel.
