==Binaural Audio==

You might have already heard about mono and stereo sound systems. Mono recordings only use one microphone and both of your speakers would be playing out the same soundtrack. Stereo recordings on the other hand use two separate microphones at a distance from each other, one meant for your left speaker or earphone to play, while the other records audio for your right ear.

==3D Audio and Virtual Reality==

In [[Virtual Reality]], 3D audio is very important for creating realistic and [[immersive]] experiences. In CES 2015, [[Oculus VR]] licensed a 3D Audio engine called [[RealSpace 3D]] and demonstrated its practical use. The 3D audio solution relies on a pair of adjustable on-ear headphones that are connected to the rest of the [[HMD]]. Those who were lucky to try it out said that it helped significantly increase the overall immersion. Chief Scientist at Oculus, [[Michael Abrash]], said that 3D sound is not an addition to VR but a multiplier. Unlike regular video games, Virtual Reality is able to use 3D audio cues to help players orient themselves in the environment and experience a complete immersion. Our 2D monitors have a limited [[field of view]] and lack the necessary information about distance, which means that while we may know from which direction is a certain sound coming, we would probably not be able to precisely estimate how far from us is its source.
