서라운드 사운드
In 2005 Wilfried van Baelen introduced the Auro-3D sound technology system to the industry. The Auro-3D format creates 3D sound by using a three-layered channel system based on the existing 5.1 Surround sound format for film. The technology adds a height and top layer to the 5.1 system. Applications also include the music and gaming industry.
