You can drag and drop SoundData.arc on the exe to extract it in the current folder, or you can run
Code:
DreamTeamSoundToolConsole SoundData.arc "output_folder"
in cmd/powershell to choose the output folder. So far the stuff in STRSE, STRBGM, and STRVOICE are playable using foobar2000 with the vgmstream component. I'm working on perfecting rebuilding of the .rsd files (Redspark audio) before I release a version that can rebuild SoundData.arc.
