Well, I had a go using old software called CTWave (man, I miss CoolEdit Pro 2.0 so much... I can't find my install discs.

)
SligTurn1.wav is recorded from the game, when the music is quiet and sligs are just off-screen.
SligTurn2.wav is also recorded from the game and was used as a reference to make SligTurn3.wav
SligTurn3.wav - Is spliced together from both SligTurn1.wav and Sligturn2.wav. It doesn't sound quite right.
SligTurn4.wav is the best "clean" sound I could record from the game. It's been modified slightly.
All can be found in the attached zip file. Maybe someone with more skill and better software than me can make SligTurn1.wav sound a bit more like SligTurn4.wav.
