1. use "Unity Studio" or "Unity Assets Bundle Extractor" to easily export the bnk file as text
2. use "bnkextr.exe" to extract the audio files as *.wav
3. rename all *.wav files extension to *.wem, you can use the "rename_wav2wem.bat" file
ren *.wav *.wem
4. run the "convert.bat" file contained to run "ww2ogg.exe", "packed_codebooks_aoTuV_603.bin" and "revorb.exe" to convert the *.wem files to playable *.ogg files
all the tools you need are in here
Thanks for the reply, but still confused from what you say about bnk file.
because I can't see bnk file extensions, even after I tried to rename it manually, I can't open it.
Can you please explain it more?
Thanks in advanceUPDATE 1 :
Never mind, I try it again and now all .wem files appears UPDATE 2 :
The result from converted sound still not right
