TrailBird AI: Zero-Signal Open-Source Bird Call Identifier for Wilderness Trails
This is a submission for the Hacktoberfest Open-Source AI Challenge Week 1: Touch Grass What I Built TrailBird AI is a zero-latency, 100% offline open-source bird call identification system engineered specifically for deep wilderness trails where cell service is non-existent. When hiking in pine forests, river valleys, or mountain passes, proprietary cloud APIs fail instantly due to zero network…
TrailBird AI is an open-source bird call identifier designed for use on wilderness trails, where cellular service is unavailable. The system operates completely offline, allowing users to identify bird species without relying on cloud-based APIs. Key features of TrailBird AI include:
1. Zero signal independence: The system works entirely on the device, without needing an internet connection.
2. Screen minimizer: The app reduces the screen to dark mode after identifying the bird, prompting users to look up and listen to nature.
3. Fast audio processing: It processes audio in just 15 milliseconds and provides a quick physical sighting tip, such as looking up in a specific tree branch.
4. Offline sighting journal: TrailBird AI keeps track of sightings locally on the user's device with timestamps.
The app works by capturing audio from the device microphone, processing it with the Web Audio API and Fast Fourier Transform (FFT), and then comparing it against open-weight acoustic models stored locally. It is built as a web application that can run on any smartphone browser or laptop terminal. All the source code is available under the MIT License.
