This amazing clip of a loud vocalizer was captured by "Jolie" at 3:41 a.m. on February 10, 2009, outside of Hattiesburg, Mississippi. To protect Jolie's privacy we are leaving out her last name. To the casual listener the clip sounds like a bizarre mechanical cacophony, almost like hydraulic machinery under stress. But when we put on the head phones, pay close attention, and scrutinize the spectrogram of this recording, several telltale characteristics emerge including falsetto notes, abrupt pitch changes, attenuated fundamental frequencies and integrated wood knocks.
The metallic sounds of the higher notes in this clip have a brassy tone, almost horn-like. This unique call is difficult for humans to replicate organically and is not commonly known to be produced by other North American mammals. The evidence that sasquatch are capable of such uniquely cryptic vocals are another intriguing element of study in the realm of this poorly understood creature.
This is not the first time these mechanical/metallic tones have been captured, but this is one of the clearest examples that also contains other important sasquatch indicators. It is recordings such as this that help us understand descriptions from witnesses, such as the metallic "ping" vocal reported in this BFRO report: "Hunter remembers his lengthy daylight sighting through binoculars near Dora". With time, more of these vocals will emerge and be added to the growing lexicon of sasquatch vocalizations.
