73,
If i get what you're saying, I think* you could use just about any sound editor/recorder to separate the sounds at a good spot, then figure out what to name them by going through the sounds folder, and making the applicable changes. At least, back in AH1, I pulled sounds from other games and stuff I found on the 'net, then cut/looped/mixed them to get the effect I wanted in AH. Assuming* HT doesn't make any major changes to sounds overall, it should still be pretty simple to do.
