Experience the iconic nighttime chorus of Puerto Rico's beloved tree frog
Inverse-distance attenuation and propagation delay place each virtual frog in 3D space around you.
Q10 ≈ 2.0 biological rate scaling with +0.8%/°C frequency shift — calls speed up as the night warms.
Puerto Rico native range (18–30°C) and Hawai'i invasive population (15–26°C) with distinct density models.
Fundamental frequencies match field recordings: 1529 Hz “co” & 2713 Hz “quí” with natural harmonic structure.
Coquí Chorus is a spatial stochastic synthesis app that recreates the nighttime soundscape of Eleutherodactylus coquí — Puerto Rico's beloved tree frog. Using bioacoustically calibrated models, temperature-dependent call rates, and real-time spatial audio, it generates an ever-evolving, never-repeating chorus that is both scientifically grounded and deeply immersive.
