I'm wondering if anyone has already cataloged the audio files?

I'm working on a replay visualizer and would like to have a consistent structure with how BW works as I wish to recreate *some* of its mechanics.
eg

marine
- select 1: someaudio.wav
- select 2: someaudio.wav
- orderattack 2: someaudio.wav

In the PyDAT unit editor, in the sound tab, you can see the sounds of an unit, and if you jump from there to the list of sounds of the game (Sfxdata) you can even listen to them.
Will that help you?

All the sound file names are contained in the ARR\SFXData.tbl file. Most are pretty self-explanatory. For Remastered, it's the REZ\Sfx.json file (it's not locale-specific so find it in the straight REZ\ folder inside the game storage, not down a locale-specific path).
