Bioacoustic monitoring of nocturnal bird migration

Project description

BirdVoxDetect: detection and classification of flight calls

PyPI MIT license

BirdVoxDetect is a pre-trained deep learning system which detects flight calls from songbirds in audio recordings, and retrieves the corresponding species. It relies on per-channel energy normalization (PCEN) and context-adaptive convolutional neural networks (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 GNU/Linux.

Installation

The simplest way to install BirdVoxDetect is by using the pip package management system, which will also install the additional required dependencies if needed.

pip install birdvoxdetect

Note that birdvoxdetect requires:

  • Python (3.6, 3.7, or 3.8)
  • librosa (==0.7.0)
  • tensorflow (>=2)
  • scikit-learn (==0.21.2)
  • birdvoxclassify (0.2)
  • h5py
  • pandas

Usage

From the command line

To analyze one file:

python -m birdvoxdetect /path/to/file.wav

To analyze multiple files:

python -m birdvoxdetect /path/to/file1.wav /path/to/file2.wav

To analyze one folder:

python -m birdvoxdetect /path/to/folder

Optional arguments:

--output-dir OUTPUT_DIR, -o OUTPUT_DIR
                      Directory to save the output file(s); The default
                      value is the same directory as the input file(s).
--export-clips, -c    Export detected events as audio clips in WAV format.
--export-confidence, -C
                      Export the time series of model confidence values of
                      events in HDF5 format.
--export-faults, -f   Export list of sensor faults in CSV format.
--export-logger, -l   Export output of Python logger in TXT format.
--threshold THRESHOLD, -t THRESHOLD
                      Detection threshold, between 10 and 90. The default
                      value is 50. Greater values lead to higher precision
                      at the expense of a lower recall.
--suffix SUFFIX, -s SUFFIX
                      String to append to the output filenames.The default
                      value is the empty string.
--clip-duration CLIP_DURATION, -d CLIP_DURATION
                      Duration of the exported clips, expressed in seconds
                      (fps). The default value is 1.0, that is, one second.
                      We recommend values of 0.5 or above.
--quiet, -q           Print less messages on screen.
--verbose, -v         Print timestamps of detected events.
--version, -V         Print version number.

From Python

Call syntax:

import birdvoxdetect as bvd    
df = bvd.process_file('path/to/file.wav')

df is a Pandas DataFrame with three columns: time, detection confidence, and species.

Below is a typical output from the test suite (file fd79e55d-d3a3-4083-aba1-4f00b545c3d6.wav):

Time (hh:mm:ss) Species (4-letter code) Family    Order         Confidence (%)
00:00:08.78     SWTH                    Turdidae  Passeriforme  70.14839

As of v0.4, species classification in BirdVoxDetect relies on a taxonomical neural network (TaxoNet), which is distributed as part of the BirdVoxClassify package. For more details on TaxoNet, please refer to:
