Bat scholocation call recordings

Description

A set of 1805 echolocation call recordings collected from 449 individual bats across 22 species and 5 families. Calls were recorded at a sampling rate of 500 kHz. The original data set is described by Stathopolous et al. (2017) (see link below). Additional features have been extracted from echolocation calls allow comparative analysis. These feature are based on a harmonic model for bat echolocation calls and the feature extraction procedure is described in Meagher (2020) (see second link below)
