What is spatial audio?
In: 2
It is just a fancy name for simulated surround sound.
You need a surround sound source (most movies/tv and some music) and manipulate it so when only 2 speakers are playin it, it sounds more enveloping than just playing a stereo source.
Some also go further with head tracking. Surround sound movies/tv have most all dialogue in the center channel. Head tracking will keep the center channel physically where the screen is, so if you turn your head to the right, the dialogue comes out of your left ear.
