How it's made
- Source
- a stylized falling object's fin-edge whistle, sustained by turbulent airflow rather than a hit. A phase-continuous fundamental combines with noise-driven Q=9 edge resonance and a weak second partial.
- Body
- default pitch glides exponentially from 1900 to 430 Hz over 2.4 s; broad Q=0.85 air bands track it. Air is high-passed at 180 Hz and low-passed below 6.5 kHz, leaving a soft breath around the tonal core.
- Motion
- a smooth late Doppler bend reduces pitch by another 7%; brightness and level crest near 70% of the fall, then darken and recede. This is a cinematic descent cue, not a ballistic measurement.
- Envelope
- 110 ms soft onset, gradual approach swell, then a 430 ms rounded release; no impact or reverb.
- Modulation
- 4.8-8 Hz fin flutter and independent smooth turbulence perturb pitch by less than 0.7%.
- Variation
- seed changes tuning by +/-1%, flutter phase and air streams. Length, size, air and tumble distinguish the standard descent, distant thin whistle, heavy close fall and unstable tumbling variants.
