gog_tw3_extract_music.sh

#!/bin/bash

# Usage: gog_tw3_extract_music.sh <game_dir>
#
# The script relies on these utilities:
# 1. QuickBMS extractor (quickbms)
#    See http://aluigi.altervista.org/quickbms.htm
#    Source: http://aluigi.altervista.org/papers/quickbms_src.zip
#
# 2. Witcher 3 BMS script to be used with QuickBMS (witcher3.bms)
#    Source: http://aluigi.altervista.org/bms/witcher3.bms
#
# 3. Wwise BNK extractor
#    Source: https://github.com/eXpl0it3r/bnkextr
#
# 4. Wwise WEM to ogg convertor
#    Source: https://github.com/hcs64/ww2ogg
#
# 4.1 Binary codebooks for ww2ogg
#    https://github.com/hcs64/ww2ogg/raw/master/packed_codebooks_aoTuV_603.bin
#
# Notes:
#
# 1. <game_dir> is the directory where the Witcher 3 is installed (which has subdir like content and etc.).
#
# 2. The script assumes, all extraction tools are placed in ${HOME}/bin/extractors
# override extractors variables when running the script if you placed them elsewhere or they are named differently.
#
# 3. By default the script will clean temporary files. If you want to preserve them for your own investigation,
# override clean variable.
#
# 4. [Optional]: To get titles for numbered files, use official TW3 Mod Kit (it works in Wine), and uncook 
#   <game_dir>/content/content0/bundles/xml.bundle
#
# Example (from Wine cmd, using <game_dir> relative to Wine's C:/ location):
#   wcc_lite uncook -indir=C:/<game_dir>/content/content0/bundles -outdir=<target-dir> -infile=C:/<game_dir>/content/content0/bundles/xml.bundle
#
# Then locate <target-dir>/soundbanks/pc/soundbanksinfo.xml which contains needed mappings.
#

It seems as if <game_dir>/content/content0/bundles/xml.bundle does not contain mappings for Blood and Wine.
Does anybody know where to find those?

@chris246: Yes, the \The Witcher 3\content\content0\bundles\xml.bundle contains the old soundbanksinfo.xml

The updated one including BaW mappings can be found here: \The Witcher 3\content\patch1\bundles\patch.bundle

Is there a difference between the GOG and Steam version? @shmerl

@chris246 @duracotton @sirwindfield: sorry, missed your comments because Github doesn't notify about them. Thanks for the heads up about the updated xml source for titles. I'll take a look and update the notes in the script.

Regarding differences with Steam, I didn't compare, since I only have GOG version. Thus the script name.

@duracotton: I just checked, and I actually don't have content\patch1\bundles\patch.bundle at all. May be latest version combines them all in content/content0/bundles/xml.bundle properly?
