3D Audio

“3D Audio” is an implementation of spatializing sound, typically by using what’s known as the Head Related Transfer Function (HRTF), that digitally processes the sound based on the position and orientation of the listeners head.

It uses the HRTF to trick the brain into perceiving the sound as if it were coming from a point in 3D space, including above or below, rather than from 2 or more loudspeakers.

3D Audio is highly relevant to the video game, virtual reality (VR) and augmented reality (AR) industries.
