Auro-3D

Auro-3D is an encoded 24 bit, 96 kHz PCM audio format, which adds 4 channels of height information to 5 Channel and 7 Channel Surround Sound. It is often referred to as 5.1.4 Channel Immersive Audio or 7.1.4 Channel Immersive Audio (a reference to adding 4 height channels to 5 Channel, 5.1 Channel , 7 Channel or 7.1 Channel Surround Sound recordings).

Using the three orthogonal axes (x, y, z) the speaker setups reproduce true three-dimensional sound as a hemisphere all around the audience. Auro-3D introduces the third dimension “Height” to movies and music, which transforms and augments their emotional impact. The Auro-3D format brings immersive 3D audio to music.

To hear the 4 height channels and the 5.1 or 7.1 Surround Sound audio in the Auro-3D encoded files, the listener will need an Auro-3D  decoder in their music system. Without the Auro-3D decoder, the Auro-3D FLAC files will play as standard 5 Channel, 5.1 Channel, 7 Channel or 7.1 Channel FLAC Surround Sound. (The decoder is what provides 4 Auro-3D height channels).
