About Auro-3D

By fully immersing the listener in a cocoon of life-like sound, Auro-3D® creates the sensation of actually ‘being there’. Thanks to a unique configuration of ‘Height channels’, acoustic reflections are generated and heard naturally due to the fact that sounds originate from around as well as above the listener. Either 1 or 2 additional layers (HEIGHT and TOP – a.k.a. “Voice of God” channel) with speakers are mounted above the existing Surround layer at ear-level to produce Auro-3D®’s defining ‘vertical Stereo field’.

Auro-3D Speaker Set-Up

The height information, captured in recording or created during the mixing process, is mixed into a standard 5.1 PCM stream that comes with a regular Blu-ray. Moreover, the Auro-3D Engine combines different technologies to guarantee an optimum 3D sound experience generated both natively and from existing audio content. It recognizes Mono, Stereo, 5.1 Surround or an Auro-encoded signal and transforms them into 3D audio. Regardless of original format, you can always experience the stunning effect of sound in 3D.
