Auro 11.1

Auro 11.1 is one of the cinematic speaker layouts of the Auro-3D format, invented in 2005 by Wilfried Van Baelen (CEO Auro Technologies, CEO Galaxy Studios). The Auro 11.1 cinema audio format is supported by Barco, a global visualization technology and digital cinema projection company.

Working

The Auro 11.1 cinema sound format adds two additional layers of sound to the existing 5.1 surround sound layer. The Auro 11.1 format incorporates a height and overhead channel which allow for sound with sound waves coming from every direction. In this way, Auro 11.1 aims to create a realistic and natural immersive audio experience.

The audio format creates immersive 3D sound by using a three-dimensional (x,y,z) 11.1 channel/speaker layout. The Auro 11.1 system is designed along three layers of sound (ear-level, height, and overhead). Based on the existing 5.1 surround sound configuration, the technology adds a height and top layer. With this audio format, natural sound comes from all around and above the listener. "The closer to natural sound, the more immersive the impact" quoted Wilfried Van Baelen in 2006 (AES convention Paris & San Francisco, where he launched the Auro-3D format with the "Auro 9.1" system).
