He needs to up the sample rate. I'm not sure that can be done with standard software. But someone just made a new sound pack in one of the other forums. Although apparently the thread degenerated to flames the participants know how or know someone who does. The basics of replacing sound files or down converting. It is possible they can point to how to upconvert sample rates. Me, I'd just find a higher sample rate file. some one has one thats high enough no matter how obscuer the source was. atthe vary least there will be someone who can resample it. I even found someone who pointed me to the old 1980's startrek arcade game's photon torpedo sound.
