I tried to roll my own alternative, but it’s a way bigger undertaking than I initially thought.
I have a quite decent audio system for Windows/Linux (MacOSX missing due to lack of hardware), so I can just skip that, if it relies on “variable size” buffers or its only audio capability being “function that plays WAV/MP3 directly”. DLL/SO preferred. I don’t need duplicates of things that are already in any standard library.
Well, you could use something like Godot for the same reason. Depends on how much work you want to do or if you need something it doesn’t provide.
