4.1 Mixing with Auro-3D


What is AURO-3D?

    The AURO-3D speaker configurations are designed along three layers of sound (surround, height and overhead ceiling), building on the single horizontal layer used in the 5.1 or 7.1 sound format.
    The AURO-3D technology creates a spatial sound field by adding a height layer around the audience on top of the traditional 2D surround sound system.
    This additional layer reveals both localized sounds and height reflections complementing the sounds that exist in the lower surround layer.
    The height information that is captured during recording is mixed into a standard 5.1 or 7.1 surround PCM carrier, and during playback the Auro-3D decoder extracts the originally recorded height channels from this stream.

Hardware Setup

    Connect the speakers to the audio outputs of your audio interface in order to mix in 3D with the AURO-3D Export plugin.
    Note that supported audio formats (immersive, surround or 1D) depends on the DAW.
    Please refer to Chapter 5: “DAW Routing Approaches” for more information.
    The following Figure 4 – 2 illustrates examples of hardware setups for the most popular AURO-3D formats.
