Wwise-Unpacker

Unpack game audio Wwise files (pck, bnk)

This guide is for Windows-64bit only!

Here's the archive structure:

• Wwise Unpacker
  • MP3 (Unpacked MP3s)
  • OGG (Unpacked OGGs)
  • WAV (Unpacked WAVs)
  • Game Files (PCK and BNK files)
  • Tools (Tools used for the unpacking process)
  • UnpackToMP3.bat
  • UnpackToOGG.bat
  • UnpackToWAV.bat

Now we have to find the audio files to unpack.

Find any containers you want to decode and copy them to the "Game Files" folder inside Wwise Unpacker (they can be either PCK or BNK, the unpacker handles it), then simply open "UnpackToMP3.bat" or "UnpackToOGG.bat" or "UnpackToWAV.bat" depending on which you like and it will do all the work for you.

Once finished you can find all decoded files inside the "MP3" or "OGG" or "WAV" folder respectively.

Things you should know about the decoder:

• Depending on the number and size of the files it can take a while, let it run until you see the notification.
• The decoder will offer to delete files in "Game Files" so you don't accidentally decode the same files again.
• When decoding MP3 files are first unpacked as OGG and then converted with FFmpeg and the LAME MP3 encoder. If you want the best quality possible don't use MP3, unpack it as WAV.
• The unpacker can be used for any game that uses Wwise audio.
• Once unpack is finished, it will delete all semifinished files to save disk space.

I unpacked to .OGG for the balance between size and quality, how do I even open these files?

You'll need a player that supports the format! Personally I use "PotPlayer" but feel free to search around and find what's best for you.

If you end up doing something with the audio (videos for example) let me know, I really enjoy looking at other people's work. Hope this helped someone!
