Arknights Endfield Closed Beta Wwise *wem extract

[NoNarluire]

Hey everyone, has anyone here worked on the Arknights Endfield audio files? Yesterday I was working on the music from the alpha version of the game and successfully extracted the music (all I had to do was rename the *.chk archives with the audio to *.pck and send those *.pck to AnimeWwiser). Today I was working with files from the Endfield beta, and unfortunately, the method I described above isn't working, and I don't know what to do now. I need to extract normal *.wem/wwise audio from the AKPK, but I don't know how. Please help. If you need the files, here's the link.

They are still pck files. I can find many wwise .bnk files in AA462ABBFEC319B665666E14585F97D9_EndfieldBeta with ravioli explorer , RavioliGameTools_v2.10.zip (if you need)and I think quickbms also work. By the way I guess the really wem audio files are in another pck files. there are over 5000 bnk files in AA462ABBFEC319B665666E14585F97D9_EndfieldBeta. That means the bnk files may not store any actual audio files

Yes, thanks, I figured out the audio files from the previous CBT (I think the first one), but the current CBT 2/3 has a different encryption, and I'm still at a loss as to how to bypass it. Even the HEX header doesn't show what kind of asset it is—audio, texture, etc. I'll leave a link to the files and hope someone can help me with this. https://mega.nz/folder/p8QwxSgQ#dfnEkkECPBFyP-aCO4MDWw

have you figured it out yet? I also want to get the audio files. I got the pck through beyondtools (https://git.crepe.moe/rfi/BeyondTools) but the pck it outputted was still encoded with the :)xD thing

https://drive.google.com/drive/folders/1jaGWTO9MLnFZTQIKKKapBVWy8tkbm97y heres the smallest pck folder. You can get all the pck yourself by using this https://cdn.discordapp.com/attachments/1173437087014469673/1443262717258371164/BeyondToolsMod-net9.zip?ex=6932faa6&is=6931a926&hm=73e3b753a2caa71c0353cb79e722c2199ce7f1f58c2e206a29d1b488770ae9d4& just cmd cd to beyondtools exe and then do BeyondTools "C:\Path\To\EndField Game\EndField Game\EndfieldTBeta2_Data\StreamingAssets\VFS" All "C:\Output\Folder"

Unfortunately, no, although I'm still interested in audio files. Previous methods didn't work on Closed Beta 3. Previously, it was enough to detect audio packets using AssetStudio, but it treats audio assets as invalid, and that's what helps detect audio packets. Then you need to rename all the candidates to *.pck and use something like AnimeWwise.

if you've already got the pck files from beyondtools. Try dragging the pck files from the main folder to this python script. Though this only partially extracts the language voicelines but it does extract almost all the music and sound effect files

Thanks for the script, and I understand it's designed for BeyondTools? I tried using script on .chk files (I downloade full package resources ArknigtsEndfield) and then opening the *.pck file using AnimeWvise, but AnimeWvise simply closes without any errors. And since the BeyondTools link from your post above no longer works, I understand I need to build a project from this resource: https://git.crepe.moe/rfi/BeyondTools.git?
