    Well, I think that is not a mystery at all. What the tarantula (I will call her "she") is doing is called stridulation. It seems like she has some kind of stridulatory organ on the prolateral face of the chelicerae (stridulatory organs can occur on different appendages and surfaces). So, when she quickly rubs her chelicerae against each other, the stridulatory organs (probably a patch of setae or rows of spines) produce that "noise".
    How much do we really know about tarantulas?
    P.S. Sorry for my deficient english...

          The other one Brendan posted still works for me:



          There appear to be a few other videos of this spider on YouTube, just run a search on "rattlesnake tarantula".
