This recording of fin whale (Balaenoptera physalus) pulses is part of a series of recordings from an oceanic soundscape project using a deep-sea cabled observatory off the California coast. More information about this research project is available in a publication.
Thanks to Mark Fischer of Aguasonic Acoustics for processing the original recording. This processing included speeding up the recording by a factor of two.

Hello. If the question is "why", the answer would be that the original recordings have very low amplitude and a DC offset. If the question is "how", Mark can best answer what he did for this clip... but for listening we typically high-pass filter to remove the DC offset, low-pass filter if the focal sound is low frequency (like blue and fin whale calls), and then amplify.
