Devil's Third Wii U Encrypted .Wem files

[GoodConduct]

Devil's third has some encrypted .Wem files and I was wondering if anyone could help me decrypt them and turn them into playable sound files. I have also uploaded some other files in case they could help. The .PCK contains a lot of other .wem files and the .bnk is unknown since its encrypted.

Another link gave me something called a WUD key but I am unsure if it is for the game files "92BEDF1789CC99D9D94FF7C8C99358C3"

*Update*
Just to had I have tried Gildor's umodel but to no success when it comes to trying to run sound files.

It turns out these files were not encrypted. I was wondering if there was a way to export them as legible files instead of number. I export them from Ravioli tools however they only come out as numbers instead of named files. I was wondering if there was a way to give the files their actual names instead of numbers via BMS script.

The "AKPK" music archives don't have filenames and have various formats, this script works with the pck you provided:
