Bioacoustic monitoring of nocturnal bird migration
Project description
BirdVoxDetect: robust sound event detection of bird flight calls
An open-source Python library and command-line tool for automatically detecting bird flight calls in audio recordings.
BirdVoxDetect is a pre-trained deep learning system for detecting bird flight calls in continuous audio recordings. It relies on per-channel energy normalization (PCEN) and context-adaptive convolutional neural network (CA-CNN) for improved robustness to background noise. It is made available both as a Python library and as a command-line tool for Windows, OS X, and Linux.
For details about the deep learning model in BirdVoxDetect and how it was trained, we refer the reader to:

Under review, 2019.
Installation instructions
Dependencies
TensorFlow
Because TensorFlow comes in CPU-only and GPU-enabled variants, we leave it up to the user to install the version that best fits their use case.
On most platforms, either of the following commands should properly install TensorFlow:
pip install tensorflow # CPU-only version
pip install tensorflow-gpu # GPU-enabled version
For more detailed information, please consult the installation instructions of TensorFlow.
libsndfile (Linux only)
BirdVoxDetect depends on the PySoundFile module to load audio files, which itself depends on the non-Python library libsndfile.
On Windows and Mac OS X, these will be installed automatically via the pip package manager and you can therefore skip this step.
However, on Linux, libsndfile must be installed manually via your platform's package manager.
For Debian-based distributions (such as Ubuntu), this can be done by simply running
apt-get install libsndfile
For more detailed information, please consult the installation instructions of pysoundfile.
Installing BirdVoxDetect
The simplest way to install BirdVoxDetect is by using pip, which will also install the additional required dependencies
if needed.
To install the latest version of BirdVoxDetect from source:
-
Clone or pull the latest version:
git clone git@github.com:BirdVox/birdvoxdetect.git -
Install using pip to handle Python dependencies:
cd birdvoxdetect pip install -e .
