Extracts BWAV files from BARS files.
This code extracts BWAV files in BARS containers and saves them into respective folders (based on their names). You can run it against a single BARS file or multiple BARS files in a folder.
BARS files are usually used as sound containers in newer Nintendo Switch games (e.g. Animal Crossing: New Horizon). They can usually be found in the Sound/Resource folder in the game's extracted ROM.
The extracted BWAV files can then be opened or converted to other more common format elsewhere (I recommend vgmstream), they are essentially a new container for sound data encoded in one of the two ways, either plain 16-bit little endian PCM (usually shorter sound effects), or Nintendo's DSP 4-bit ADPCM (longer ones).
This code depends on the filesystem API that's introduced in C++17 (or C++14 experimental, change from #include<filesystem> to #include<experimental/filesystem> if you have to use C++14) for directory related stuff. If you can't use C++ 17, there's an alternate boost supported version, run make compile-boost to build that version.
Run make to build the default executable.
This code is written and roughly tested on Ubuntu 20.04 and Windows 10 (using MinGW), it should be cross-platform, but I didn't test it elsewhere.
Built executables for Ubuntu and Windows can be found in the releases section.
bars-to-bwav <bars file or folder containing bars files> [bwav output folder] [--no-overwrite]
or: `bars-to-bwav -h` to bring out this menu.
add `--no-overwrite` flag to prevent from overwriting files with the same names.C++17 is mostly supported since GCC 5, although it seems that the specific filesystem APIs are not supported until GCC 8.1. Unless you are using a really old GCC version, you should be fine.
Use g++ --version to check for your g++ version, and you can grade it to the latest version (on Ubuntu) with sudo apt install gcc g++.
You can run make test-cpp to test if you are using C++17.
