## What is Coquí Chorus?

Create infinite, scientifically-accurate nature soundscapes with 11 species of frogs, birds, and insects — all synthesized in real-time from bioacoustic research.

No recordings. No loops. Every listening session is unique.

MIX YOUR OWN SOUNDSCAPE
• 11 species: Coqui, Spring Peeper, Bullfrog, Gray Tree Frog, Cricket, Katydid, Great Horned Owl, Canada Goose, Common Loon, Green Tree Frog, American Toad
• Adjust population, volume, and distance for each species
• Temperature-responsive calls using real Q10 thermal models
• Spatial audio with randomized positions

SLEEP & FOCUS
• Built-in sleep timer (15, 30, or 60 minutes)
• Gradual fadeout for natural transitions
• Background audio — works with screen off
• No ads, no interruptions

SCIENCE-BASED SYNTHESIS
Each species is modeled from published bioacoustic research — frequency spectra, temporal patterns, and thermal sensitivity. The result sounds real because the math is real.
