CASE (Cluster & Analyse Sound Events)

A tool to evaluate bioacoustic studies easily and automatically

By means of this tool it is possible to extract up to 44 features of an animal sound in different ways. In addition, the tool includes various clustering algorithms (community detection; affinity propagation; HDBSCAN and fuzzy clustering) as well as algorithms to detect similarities between signals (k-nearest-neighbor; jaccard; dynamic-time-warping) in order to effectively classify animal sounds. The tool uses a graphical user interface to allow the user to work with the software as easily and intuitively as possible.

The following algorithms were adopted:
