In everyday folklore, a barking spider is the supposed source of an otherwise unexplained fart. The joke works because the sound is instantly recognisable and the creature is remarkably difficult to produce on demand. The recordings here are sound effects that illustrate that usage. Real Australian tarantulas also have regional names including barking and whistling spiders; their defensive stridulation is a different subject.

Listening notes and recording details →How to compare the recordings
Listen for the first attack, the number of pulses, and how long the sound remains after the source stops. A room echo can make a short source seem much longer. Describing those features is more useful than turning the volume up.
