Funny, Sombre asked exactly the same. Those aren't encoded at all. They're raw PCM data. The only thing that I don't know is their frame rate. sling.sw, the sound for the sling shots, is probably 11kHz stereo (or 22kHz mono), as is earth.smp, which I think is the sound that the earth elementals make when trampling. But howl.smp, for example, does have at most half that rate. growl.smp might be 6kHz mono or something, same for elefant.smp, the elephant sound.

So yes, I think I could normalize those sounds a bit. I'd have to look if the frame rate is saved in the game or in the files, which should be quite easy to do (just rename some). An easier fix is to just overwrite elefant.smp with muller.smp or earth.smp, which are easier on the ears.
