'Bat detectives' train new algorithms to discern bat calls in noisy recordings

Using data collected by citizen scientists, researchers have developed new, open-source algorithms to automatically detect bat echolocation calls in audio recordings. Oisin Mac Aodha, formerly of University College London, now at Caltech, and colleagues at University College London present their new approach in PLOS Computational Biology.

Nearly 80 percent of bat species use echolocation calls for...
