Auro-3D
Auro-3D is a new sound format, which adds both height and top layers of audio to create a fully immersive
surround sound experience. Auro-3D incorporates both a decoder, to play back discrete 3D sound mixes (up
to 13.1 channels) in their native format and an upmixer, which can create an Auro-3D soundtrack from any
source.
Auro 9.1
The minimum configuration for Auro-3D is Auro 9.1, which starts with a base 5.1 layer and adds height
speakers corresponding to the Left, Right, Left Surround and Right Surround channels. The height speakers
should be placed directly above their corresponding lower layer speakers. The ideal height placement is 30
degrees above horizontal from the listening position. The height speakers may be angled down slightly, but
not so much that the speakers are pointed at the listening position.
Auro 10.1
Auro 10.1 adds a recommended overhead speaker, directly above the listening position.
