Hybrid millidecade bands computed from the acoustic data collected in the LifeWatch Broadband Acoustic Network. Hybrid millidecade bands computed according to Miksis-Olds et al. 2021 [1]. The output is given in power spectral density. The data were processed using pypam [2], in non-overlapping 1-minute windows. Each window is processed using a 1-second fft. Frequency range from 0 to 24 kHz. For data with a sampling rate higher than 48 kHz, a low pass Butterworth filter of order 4 was first applied to the raw data before computing the hybdrid millidecade bands. [1] Miksis-Olds , J.
