How it's made
- Source
- an imagined giant membrane driven by breath; a 42-78 Hz fundamental glides down 25-44%. Six sine partials model periodic vibration, with 0.7 Hz pitch wander and gentle amplitude flutter.
- Body
- pink turbulence excites broad moving throat cavities near 2.8 and 5.2 times the fundamental; Q 1.4-2.1 gives a hollow chest without a narrow whistle. Upper partials lose energy first.
- Envelope
- pressure builds over 0.9-1.55 s; the voiced body then relaxes over roughly 3 s. Breath peaks slightly earlier, while the fundamental carries the long descending tail.
- Space
- low-pass absorption at 420-1100 Hz and quiet 170/310/530 ms filtered arrivals suggest a distant underwater source. These finite arrivals are part of the call, not a room reverb.
- Variation
- seeded tuning +/-0.8%, partial phases and independent throat turbulence; pitch, fall, swell and distance alter anatomy and propagation. Presets span abyss, lament, warning and far field.
