@littlest-lily Can you imagine what (or who) put those 3D audio thoughts (literally) in my head, uh?
For a static recording, on the hardware side I think there are binaural microphones that allow you to record directly in 3D. Or, like @skysayl said, you can use manual panning to get the same effect but I guess there’s more work involved. My only experience is mixing music but that’s another ball game.
I’m doing research for a little project of mine on the software side of things, namely audio APIs, algorithms to simulate realistic spatial audio effects, room acoustics, sound source directivity, and HRTF functions. But that’s mostly about how to transform existing sounds to 3D in realtime for, say, a VR environment.
