Location: Morretes, Paraná — Atlantic Rainforest, Serra do Mar, Marumbi Watershed, Brazil.
Hardware: AudioMoth USB Microphone (384kHz capable) plugged into a Raspberry Pi running 24/7.
Pipeline: The Pi captures raw PCM audio at 48kHz via ALSA, streams it over a WebSocket to this server. Every 3 seconds, the server runs a 10-second window through the AVEX esp_aves2_sl_beats_bio model (12,279 bioacoustic classes). Predictions are filtered to 589 species known to occur in this region — only local birds, mammals, amphibians, and vocalizing insects are shown.
Stack: AudioMoth → Raspberry Pi (Python, ALSA) → WebSocket → FastAPI + PyTorch (AVEX) → your browser.
Capture settings: 48 kHz / 16-bit / mono • RMS threshold 300 • silence timeout 2s • max segment 60s
