This is when recording marine mammal echolocation. Some species click at high frequencies (e.g. harbour porpoise at 140 kHz), hence the high sampling rate. For some analyses when I don't need the higher frequencies, I resample at a lower rate because it's easier on PC resources and I can use shorter fast Fourier transform windows to look at spectrograms of the sounds in frequency domaine.
