trilha: identifying birds by ear on the trail, with no signal
Описание и применение
Инструмент "trilha" позволяет офлайн‑обрабатывать аудио‑записи с тропы, распознавать птиц и генерировать поле‑заметку без ошибок в названии места.
Задача
Field researchers need to identify bird species from audio recordings taken in remote trail locations without relying on cellular or satellite signal, and record observations in a trustworthy field journal.
Результат
The tool processes a 5‑minute recording in 5.2 s on CPU, identifies 596 species in range, and outputs a concise field note without hallucinating species or counts. After prompt refinement, it also avoids inventing place names, ensuring the journal reflects the actual location.
Рабочий процесс
- 1. Record audio on trail.
- 2. Transfer WAV file to laptop.
- 3. Run
trilha listen <file> --lat <lat> --lon <lon> [--place "<name>"]. - 4. BirdNET 3.0 slices audio into 3‑s windows and scores each window for 11,560 species.
- 5. BirdNET’s range model narrows candidates to 14,082 species, then to 596 species in the specified location and week.
- 6. Gemma 3 generates a prose field note from the detection list, respecting prompt constraints to avoid hallucinations.
- 7. Output detections and field note to console or file.
Доказательства
trilha is a command-line tool that does the whole thing on your laptop, offline. It listens to a recording, names what it heard, and writes the outing into a field journal in prose.
BirdNET 3.0, through ONNX on CPU. It knows 11,560 species. It slices the audio into 3-second windows and scores each window independently...
The filter — BirdNET's range model, 14,082 species. Give it latitude, longitude and the week of the year, and it narrows the candidates to what could plausibly be there right now.
The voice — Gemma 3, through Ollama, on my machine. It turns the detection list into a few sentences for the journal.
The field note came back like this: "Field note Aqui está a nota de campo em português: **Nota de Campo – Reserva do Pampa** ..."
I added the rule I'd been missing: "Only ever refer to the location exactly as it is given to you."
