Bird-Song-Detector

Bird-Song-Detector is part of a research to improve bird vocalization identification. The Bird Song Detector is designed to detect bird vocalizations in audio files using a YOLO-based model from the BIRDeep project. The system converts audio files into spectrogram images, performs bird song detection on these images, and transforms the predictions into time segments.

The model has been trained on the BIRDeep dataset, which consists of audio recordings from Doñana National Park, located in Huelva, Spain. As such, the detector is particularly well-suited for identifying bird songs from this region and has not been tested on data from other areas.

For more information, visit the full BIRDeep Bird Song Detector repository.

This repository is part of the manuscript "A Bird Song Detector for Improving Bird Identification through Deep Learning: A Case Study from Doñana", which is currently under review.

Setup

1. Clone the repository:

   git clone https://github.com/yourusername/Bird-Song-Detector.git
   cd Bird-Song-Detector

2. Create and activate conda environment from environment.yml:

   conda env create -f environment.yml
   conda activate bird-song-detector

3. Install dependencies:

   pip install -r requirements.txt

Usage

Detect Bird Songs in a Single Audio File

Run the script predict_on_audio.py to detect bird songs in a single audio file:

python Code/predict_on_audio.py

Detect Bird Songs in Multiple Audio Files

Run the script predict_on_folder.py to detect bird songs in all audio files in a folder:

python Code/predict_on_folder.py

Web Interface

For a more interactive experience, you can run the Gradio web interface (app.py) by executing the following:

python App/app.py

The web interface will be available at http://127.0.0.1:7860/ by default. On the main page, drag and drop your audio file into the upload box and click Detect Bird Song to process it.

Once the detection is complete, you will see the following:

• A list of predicted bird song segments with their start time, end time, and confidence score.
• The corresponding spectrogram image with bounding boxes indicating detected bird songs.

You can then click on the Generate Segments button to download a ZIP file containing the individual detected audio segments in WAV format.

The generated ZIP file will contain the predictions WAV format with the name of original audio file followed by the start and end time of the detection and the confidence score.
