I've done some soundpacks mostly for myself, and the program I use is Adobe Audition 1.5, it HAS to be this version in order to work.
also, I don't remember from where did I get this info but, when exporting the sounds these are the forms they have to be in order for them to work:
Winsotn_ (cockpit)
Rate(Hz): 22,050
Bit depth: 16
Channels: Mono/Stereo
Winston_ext_,Winsont_extd_ (external sound)
Rate(Hz); 22,050
Bit Depth: 16
Channels: Mono
Win_,Winnf_ (AI Sound)
Rate(Hz): 22,050
Bit Depth: 16
Channels: Mono
Player Engines are as follows.
winston_ &win_### = Cockpit
winston_ext_### = External
winston_extd_### = External
Ai Engines are as follows.
winnf_###
###: varies from one sound to another as of high, med, low, start, etc.
