the ones with 0xFFFF can be converted to vorbis using ww2ogg, and the other two can be converted using WEMConverter.
for some reason however some files have a riff/wav header, format tag for pcm but opus data (3DB1EB9C11E1A414.bin for example) and all the vorbis files don't even open in the official wwise tools, so 0xFFFF isn't standard to wwise either as it seems.
if that's not confusing enough some files aren't even sound files but something entirely different. even the ones with the same header have different contents, some have 0x48 long chunks that start with SMP2 (AC3BA5BDDAB3D92B.bin for example) and some others that make no sense to me at all (94D354EE54E0A03F.bin for example).
the file names might be different on other versions, these are from v1.04
maybe this helps someone
