How do front speakers emulate surround sound?

495 views

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?

There is something called binaural audio (HRTF filtering) that creates auditory illusions by recreating the effect that the shape of your ears have on audio behind you etc to mimic uncanny localized sounds (there is a really good barbershop sound demo out there somewhere). But afaik that only works well with headsets.

TLDR; no idea
