Mixing for DolbyAtmos
®
with a
Dolby Rendering and Mastering
Unit (RMU)
14
Object-based mixing for Dolby Atmos requires a connection to a Dolby RMU and the
installation of the “Nuendo RMU Connector for Dolby Atmos
®
”.
If the “Nuendo RMU Connector for Dolby Atmos
®
” is installed, the following functions are
available:
•
The Object Mapping dialog that allows you to establish a connection to a Dolby RMU
and to define your audio objects by mapping audio outputs to object IDs. Mapped audio
outputs that are connected to output busses in the VST Connections window serve as
your object busses.
•
An additional Object Mode in the VST MultiPanner that allows you to pan audio objects
and to route the signal through object busses to the Dolby RMU.
Object Routing
To be able to create an object-based Dolby Atmos mix with the VST MultiPanner, you must
first connect your system to the Dolby RMU, define objects, and create object busses.
Connecting Your System to the Dolby RMU
Your system must be connected to the Dolby RMU. The last used connection to an RMU
persists and is restored when you start the application.
Set up the connection between your system and the Dolby RMU as follows:
•
In the Object Mapping dialog, enter the IP address of the Dolby RMU into the RMU
field.
Defining Objects
If you want to use an audio stream as a Dolby Atmos object, you must map an object ID to
this audio stream first.
A Dolby Atmos object consists of an audio stream that is sent to the Dolby RMU plus a meta
data stream transporting the panning information. Objects are always sent in real time,
and are monitored and recorded in the RMU. For this to work, you must define which audio
streams that are sent to the RMU are objects. This is done in the Object Mapping dialog.
NOTE
The total number of objects is 118. However, the first 10 objects are reserved for the 9.1
Dolby Atmos bed and are excluded from mapping. Therefore, it is recommended that the 9.1
Dolby Atmos bus uses the first 10 device ports of your audio interface.
