[Question] How can I use the dll for my own purposes?

[ego-lay-atman-bay]

I have found that this program is able to decompile the audio in mario kart tour much better than the program I had been using before, but the problem is, I want to automate the process. I know there's a dll file, as well as the source code, so I know it's possible. The game that I'm specifically extracting the audio from is Mario Kart Tour.

I'm wondering if there's anyone who can explain how the dll api works, and if it's possible to use it from the command line.
