A python api for BirdNET-Lite and BirdNET-Analyzer

Installation

birdnetlib requires Python 3.7+ and prior installation of Tensorflow Lite, librosa and ffmpeg. See BirdNET-Analyzer for more details on installing the Tensorflow-related dependencies.

pip install birdnetlib

Documentation

birdnetlib provides a common interface for BirdNET-Lite and BirdNET-Analyzer.

Using BirdNET-Lite

To use the BirdNET-Lite model, use the LiteAnalyzer class.

from birdnetlib import Recording
from birdnetlib.analyzer_lite import LiteAnalyzer

# Load and initialize the BirdNET-Lite models.
analyzer = LiteAnalyzer()

recording = Recording(
    analyzer,
    "sample.mp3",
    lat=35.4244,
    lon=-120.7463,
    week=18,
    min_conf=0.25,
)
recording.analyze()
print(recording.detections) # Returns list of detections.

recording.detections contains a list of detected species, along with time ranges and confidence value.

[{'common_name': 'House Finch',
  'confidence': 0.5744,
  'end_time': 12.0,
  'scientific_name': 'Haemorhous mexicanus',
  'start_time': 9.0},
 {'common_name': 'House Finch',
  'confidence': 0.4496,
  'end_time': 15.0,
  'scientific_name': 'Haemorhous mexicanus',
  'start_time': 12.0}]

Using BirdNET-Analyzer

To use the newer BirdNET-Analyzer model, use the Analyzer class.

from birdnetlib import Recording
from birdnetlib.analyzer import Analyzer

# Load and initialize the BirdNET-Analyzer models.
analyzer = Analyzer()

recording = Recording(
    analyzer,
    "sample.mp3",
    lat=35.4244,
    lon=-120.7463,
    week=18,
    min_conf=0.25,
)
recording.analyze()
print(recording.detections)

Project Goals

• Establish a unified API for interacting with Tensorflow-based BirdNET analyzers
• Enable python-based test cases for BirdNET analyzers
• Make it easier to use BirdNET in python-based projects
• Make it easier to migrate to new BirdNET versions/models as they become available
