<p>Passive Acoustic Monitoring (PAM) recently extended to a very wide range of animals, but no available open software has been sufficiently generic to automatically treat several taxonomic groups. Here we present Tadarida, a software toolbox allowing for the detection and labelling of recorded sound events, and to build an automatic classifier to sort <a></a><a></a><a>any new acoustic data </a>into known classes. It is made up of three modules handling Detection, Labelling and Classification and running on either Linux or Windows. This generic, modular and interoperable design opens numerous reuse opportunities among (bio)acoustics researchers.</p> <p>The whole toolbox is openly developed in C++ (Detection and Labelling) and R (Classification) and stored at https://github.com/YvesBas.</p>
