[Help] How can I generate images or audio?

Hey, could someone explain me (no AI/ML background) on how this model could be used to generate images or audio?
I can generate 3 x 3 tensors in code, no problem, but what's the next step to leverage these tensors?

I'm pretty sure I'm not the only one who will stand here and think to himself: "what now?"
I would appreciate a hint or anything that would explain how I could use these tensors without having to read the paper (which I tried but didn't really grasp).
