Quality
Hey there!
I am not 100% sure about this one, but it feels like the sound quality is worse after using Wwise-Unpacker. I used it for Assassin's Creed 4. I used OGG of course, for obvious reasons (AIMP 3 plays everything LOL). The bitrate of the audio files was various and could differ a lot, from 1kbps (LOL, 1-2 min long silent files) to ~300kbps rarely. Most of them were about 100-200. In addition, vast majority of them were 32kHz, not 44,1kHz :/ That seems pretty low for the AAA Studio game, also when I listened to some songs on Youtube, they sounded much better.
I found this tool: https://github.com/losnoco/vgmstream, which converts Wwise files to WAV.
Its test.exe tool can be used like:
test.exe -o sfx_sound_123_norm.wav sfx_sound_123.wav
And the sfx_sound_123_norm.wav will be a classic playable WAV file. The files converted/extracted by quickbms should have the .wem extension, I think, to distinguish them from the WAV files. At least the mentioned vgmstream/test.exe recognizes it if you put the .wem type for the input file.
The resulting WAV file will be as lossless as possible after the quickbms script has extracted Wwise sounds from the package.
