Co to jest?

3D audio, often referred to a s saval audio, is a sound reproduction technique that places audio objects in a three-dimensional space around the e listerer. Unlike conventional stereo sound, which sich uses only left andd right channels, or surround sound setups that rely on multiple fizycal speakers, 3D audio creates the illusiof sounds coming from any diredirection, including g above and below.

At it core, HRTF models how the shape of a person 's head, hes, and torso alters sound waves before they reach thee eardrum.
