Four whole hours LOL.
Whale hydrophone sound is composed of 4 or 5 different audio samples obtained by applying a band-pass filter to the same recording. What you hear is a combination of them. Each sample will fade out at different ranges: when the whale is far away, you can only hear the lowest frequencies, but when the whale is at close range you hear the whole spectrum.
