Voice audio of four marine mammals

We used the recording data of four marine mammals from 1940 to 2000 provided by the Watkins Marine Mammal Sound Library, namely 'Killer Whale', 'Humpback Whale', 'Pilot Whale', and 'Bottlenose Dolphin'. This sound library provides researchers with three options for experimental use: selected clips, complete clip sets, and original tapes [39]. This paper relies on selected clips. This part of the data further shows the wide applicability of our model because it covers different time periods, geographical locations, and recording equipment.
