How it's made
- Source
- a stone pestle rubs seeds against a rough mortar; pink friction spans 180 Hz to 5 kHz. Filtered sparse impulses add fine asperities; 2-5 ms attacks and 9-30 ms tails model seed fractures.
- Body
- the loaded stone bowl has damped inharmonic modes at about 460, 790, 1280 and 2150 Hz, with 25-65 ms decays. A broad 240-390 Hz contact band supplies weight without sub-bass rumble.
- Envelope
- 4-12 circular strokes per six seconds; smooth pressure lobes drive level, brightness, grain density and fracture probability together. Contact persists between the pressure peaks.
- Variation
- seeded drift models uneven hand pressure; each fracture varies colour, length and pan. Rotation count stays integral over six seconds; the renderer crossfades stochastic seam detail.
- Presets
- fine powder softens fractures; coarse seeds emphasize crunch; slow heavy strokes lower the bowl modes; brisk grinding raises stroke rate and brightens the friction. Dry, close perspective.
