Both
@Thomasphoenix98 and
@Litlgi74 have written at page #913 in this thread that Auro-3D only works in 16 channel mode.
Have a look at the attached picture. That picture has been posted by Gilles Gerin, the French business partner of Smyth Research, at the French distributor’s
Facebook page, when he announced the imminent arrival of Auro-3D for Realiser A16.
In the left upper corner, one can notice SVS 24CH. Moreover, in the right upper corner of the display, one can see that the listening room was set for Atmos, while the actual audio was Auro-3D. Is that possible to get Auro-3D audio in an Atmos listening room?
