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.
Do you need to write your own engine?
If not, check out Godot Engine.
I’m writing my own engine, I want to cut time on porting stuff to different systems.
Well, it seems I might have to resort to “plagiarism” instead…
APIs handling these stuff are barely documented due to “you can just use xy middleware to do that easier” (only for xy middleware still using DirectInput 8 among many other problems), or the OG documentation being completely barren and obvious issues often not being documented anywhere.
