So far I have found 6kHz & 11.025kHz, but the program that I am using seems to barf when I try to save the new sound at 6kHz. The original elephant sound was 6kHz, but I saved it as 11.025kHz (mono) and it sounds fine in game.
Would f_death be the shriek of the lovely ladies when the perish? That one is already high on my list of irritating sounds.
It will likely be tonight before I can get to it.
