How it's made
- Source
- a body parts tall grass; pink-noise air displacement under white-noise blade friction.
- Body
- air occupies 180-1400 Hz; flexible blades make broad 0.7-4 kHz friction, Q 0.55-0.8. Cascaded low-pass filters soften energy above 4-7 kHz; no pitched stem modes or reverb.
- Envelope
- a 0.64-1.12 s pass swells over its first 40 percent, then fades as blades slide free. Friction brightens at closest contact and darkens during release; air leads blade motion slightly.
- Events
- 13-25 overlapping blade contacts have 12-32 ms attacks and 45-110 ms releases. Contacts cluster around passage, with a weaker late brush from recovering blades; no hard snaps.
- Modulation
- independent 12-27 Hz smoothed noise gives friction an irregular fibrous flutter.
- Variation
- seeded timing, colour, strength and narrow panning; length controls crossing time, dryness controls upper friction, thickness controls overlapping contacts, spread controls width.
- Presets
- quick green brush, soft lush passage, dry seed-head swish and dense grass crossing.
