Adaptive Airway Lab
Standalone source–filter study page: modular models for mammal larynx, deep avian syrinx, and frog membrane with explicit trachea/OEC/beak filtering.
- Research anchor: upper respiratory tract remains an active acoustic filter.
- Fix: trachea length changes propagation-derived resonances.
- Fix: OEC volume reshapes full-spectrum filtering, not only one band.
- Fix: pressure threshold drives entry into nonlinear regimes.

Comparison against prior pages + supplied synopsis
| Research requirement | Throatazoid gap | Syrinx gap | New page correction |
|---|---|---|---|
| Source should cross phonation threshold from pressure. | Internal glottis is mostly imposed oscillator control. | Threshold behavior exists, but model remains preset-centric. | Unified pressure threshold and explicit nonlinear-region transition for all model families. |
| Trachea length and beak/gape should move resonances in mid bands. | Body-length controls often reshape geometry without dedicated tract-delay emphasis. | Length is present, but adaptation remains one shared topology. | Trachea, beak, and OEC controls are independent across mammal/bird/frog templates. |
| Oropharyngeal-oesophageal cavity should act as full-spectrum filter. | No explicit OEC-first framing for comparative animal use. | OEC mostly approximated by modal coupling labels. | Dedicated OEC volume and junction controls remap global resonance and damping. |
| Support multiple anatomies instead of one universal organ. | Alien branch model, not biologically grouped source families. | Broad coverage but fixed species lock and shared tract framing. | Model families + animal presets keep anatomy and gesture modular and swappable. |
