The Dolby Atmos Mastering Suite is designed to replace what was formally know as the “HT-RMU” software, which is the version of the RMU designed for nearfield mixing rooms being used to create content for Blu-ray and Digital Delivery.  This software is not designed for mixing movies in large theatrical mix rooms, or creating master files destined for DCP Delivery.  For this workflow a cinematic RMU is needed, which is provided to approved rooms through the existing Content Services room approval program.

The Dolby Atmos Mastering Suite allows for creation of consumer Dolby Atmos master files (.atmos), whereas the Theatrical Mastering suite allows creation of PRM style print masters, along with the DCP MXF Atmos file.
