I have a 2 speaker + 1 subwoofer setup for my computer and it’s really good. I can hear enemies coming at almost any direction, even behind me when I’m playing games. How do my two speakers in front of me make sounds that sound like they’re coming from behind me? Is it some sort of auditory illusion?

It has to do with the shape of your ear. Your eardrum is just like a microphone, it doesn’t actually know where any sound is coming from, your brain is just really good at picking up subtle clues in the sound that lets you distinguish the direction through the asymmetry of your ear. Well, what if you made it “sound” like when your ear hears it from behind, and then just played it through a speaker? Your brain would interpret the very subtle differences as the sound coming from behind you, even though it wasn’t. So yes, it is an auditory illusion created by making it sound like it’s behind you through subtle digital manipulation.
