Similarly to this discussion (Is it common to have a negative-positive dB range in underwater spectrograms?), I used the 'seewave' R package to plot the below spectrograms.
I limited the coloured ...

What is the purpose of this?

Background:
As an example, the Swift recording device can record at a sampling rate up to 96 kHz (with a corresponding effective rate of 48 kHz). However, the highest frequency response that the ...
