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.

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.
