Down-Chorus

说明与用途

该应用让徒步者录制鸟鸣，步行后上传检测结果，过滤误报，播放参考音频，并生成简洁的离线野外日志摘要。

问题

Birdwatchers rely on phone screens to identify calls in real‑time, draining battery and often misclassifying wind or car horns as rare birds.

结果

The app reduces phone screen time to about 1 minute after a 45‑minute walk, filters out false positives using seasonal and temporal priors, and generates a naturalist summary offline with no external API calls.

工作流

• Record morning bird sounds with phone in pocket
• Upload BirdNET CSV to the web app
• Backend parses CSV and applies region/season/time filters
• Verified detections are displayed on an interactive SVG timeline
• Click a bird to hear its call from Xeno‑canto
• Optional: LLM (Gemma 3 1B) generates a field‑journal summary
• Review summary (≈1 min) after a 45‑minute walk

证据

When people go birdwatching, they stare at their screens trying to identify calls in real-time. This ruins the walk, drains phone battery, and sound classifiers often make mistakes (confusing wind or car horns with rare birds).

来源

The app checks each detection against local seasonal and morning-hour data, dropping false positives and keeping only verified birds.
