Installation

Either install the latest stable release from PyPI

pip install ChimpDrummingDetector

Alternatively, you can install this package through to code on this repository. Simply download this repository as a zip, and then do:

cd path/to/downloaded/zip
unzip ChimpDrummingDetector.zip
cd ChimpDrummingDetector
pip install ChimpDrummingDetector

Usage

In your python code, do

import chimp_detector

path_to_wave_to_analyze = path/to/wave.wav 
detection_result = chimp_detector.detect_drumming(path_to_wave_to_analyze)

• Input: A wave file. Might be mono or stereo
• Output: A pandas dataframe with following columns
  • timepoints_in_seconds [float]: The analyzed timepoints
  • drumming_probability [float]: Probability of chimpanzee drumming in range [0,1] for the respective timepoint
  • drumming_binarized [boolean]: Binarization of probability with threshold 0.5, where TRUE means "there is drumming in this frame".

Dependencies

This Packages requires:

• Python version 3.8
• librosa==0.8.0
• tensorflow==2.3.1
• pandas==1.1.2
• numpy==1.18.5
