What Spatial Audio Does and Why It Can Sound More Immersive
A pair of headphones has only two earpieces, yet some films and games can make a sound seem to come from in front of you, behind you, or somewhere above you. Features labelled spatial audio, 3D audio, or virtual surround are designed to create that impression. The useful idea is simpler than the names suggest: spatial audio tries to reproduce some of the clues your hearing normally uses to locate real sounds. It does not literally place a speaker behind your head. Instead, the playback system changes the sound reaching your ears so your brain can interpret it as coming from a particular direction.
