Dolby Atmos Binaural Settings Object Groups/Beds

Hello
I am working in both Pro Tools and Nuendo for mixing Dolby Atmos.

In Cubase/Nuendo I create 7.1.4 group track then make it into an object bed. The objects become automatically assigned in the ADM authoring for example 11-23 objects. In Cubase/Nuendo I only have the option to set binaural settings of the 7.1.4 group to a single setting ie near, mid, far. So all the object channels share the same binaural setting.

This is not ideal because in any object bed you may want to change the front L R to near binaural and have the tops to far, etc.

In Pro Tools either internal or external renderer I can change individual object binaural information on any object group or single.

In Cubase/Nuendo how do I change individual object binaural settings inside of a multi channel object group/bed?

Thanks!!

That’s very easy to do, I am not with my machine but will do a short video once I have access to my machine. But meanwhile you can refer to page 857 of the pdf manual. 12.20. Binaural render mode for beds .

You can change the individual settings for the main 7.1.2 BED but looking at DIA Church verb in your screenshot, how would you assign Objects 27-31 to unique Binuaral Settings vs having them all set to Mid which is what you have here. Thanks!

Its set to ‘mid’ by default but you can change it to ‘far’, or dialogues to near etc. You have to keep in mind that the distance value embedded in the Audio Definition Model (ADM) metadata serves only as a cue to the streaming server to deliver the perceived position in Dolbys own generic implementation of head-related transfer function. Most binaural streaming services ignore it as they recreate the binaural effect from the actual positional data embedded in the Audio Definition Model (ADM) by utilising a personalised HRTF measurement of ear and head.

Are you trying to master surround mix using the headphones only.

Hi Rajiv, thanks for your response although I do not think you understand my question.

I work professionally in Dolby Atmos mixing for Major and Indie labels as well as artists. I do much of my work in Pro Tools and external Dolby Renderer and you can easily change binaural settings per object via the Binaural Render plugin.

Cubase/Nuendo just has different implementation and I do enjoy working in Nuendo so am trying to figure out how to change Binaural settings in a very detailed way per object and I am afraid it is just not possible.

My Fault, I may have misunderstood your question.
Is this Protools specific workflow that you are missing.
I thought that you wanted to know whether you can change binaural settings per object (Stereo/Mono channel clip as object) such as near far mid and so on. as shown below, you certainly can.
So just to understand your issue better by 7.1.4 group you meant multi object hosting 7.1.4 channel clip! and not mono or stereo….This multi object hosting might be Nuendo only feature….


I think I have found a rather convoluted way to mimic the PTools Obj bed model.

If you’re still interested let me know

Why would Nuendo 14 be released and not address this issue? Perhaps so few engineers mix for music Atmos in Nuendo and the object bed concept is not understood by the engineers. I just don’t understand why you would have no control over each objects binaural settings in an any channel with more than one object. In a 9.1.6 group channel converted to objects per channel I can only select off, near, mid, far for all objects in the 9.1.6 group. Just doesn’t make sense. There is a very simple clear way to do this in pro tools so it is possible.

every one of the 118 possible objects can have its own unique off/near/mid/far regardless of whether its routed to a Group Bus ‘BED’ or not. In Nuendo you can route all your created objects to an ‘Object Bed’ and all created object channels have and retain their own individual off/near/mid/far settings. Am I not understanding your problem?

Thanks for your response.
As far as I am aware if you create a simple group bus in say 7.1.4 then you go into ADM Authoring and go into Functions drop down and Create Objects from Selected Track then it will make that 7.1.4 Bus and Object bed with 11 objects that are grouped together as a single Binaural setting in the ADM Authoring window. As far as I have found there is not a way to then go into this group of objects and break them out into seperate binuaral off, near, mid, far settings.

I am also attaching a typical looking 7.1.4 OBED in Pro Tools so can you see it is setup for adjustments to each channel’s binaural settings.

You can see in Pro Tools there is an option on the right side under the Object assignment to adjust those off, near, mid, far settings.

I am unaware of a similar functionality to go into that level of adjustment in Nuendo and yet it is crucial for anyone working in Atmos. Also, this is true for Stereo channels where the two channels are assigned the same binaural setting.

I would love to be wrong on this.

Just out of curiosity, why use an object group and set the individual parts of it up like this?

It depends on the project, but sometimes I’ll set up a multichannel bus (7.1.4, etc.) as an object-based bed. Then I’ll create stereo aux channels assigned to spatial “zones” — FRONT, SIDE, REAR, TOPS. I assign the output of those stereo aux channels to the 7.1.4 object bus and pan each one to its respective location — for example, FRONT would go to the traditional front left/right speakers, SIDE to the side surrounds, etc.

The idea is that I can route any audio or aux channel either directly into the 7.1.4 bus and pan it in that space, or route it through one of the stereo zone buses.

In a stereo stem-heavy “remix”-style project, I’ll assign those stereo stems to the zone channels as a quick method to explore spatial panning ideas. For example, vox might go to FRONT, a synth to REAR, etc. It’s a practical method for handling large projects without needing to assign discrete objects to every track. Instead, those stereo zone buses feed into the 7.1.4 object bus, and I can assign front wall to Near, wide/side and rear to Mid, and tops to Far binaural settings. That gives the mix depth and spatial quality in headphones — for anyone who actually hears the Dolby Binaural mix… haha.

Now imagine a mix with, say, 30 separate stereo stem audio tracks from a completed mix, all routed into this group of aux zone buses which ultimately feed into the 7.1.4 bus. I can add a FabFilter Pro-Q4 or Pro-L in 7.1.4 format on that bus and treat it like a full mix bus. I also use some compressors that support channel linking and sidechaining in 7.1.4, allowing me to apply full-range mix bus compression.

There is always the creative option of making one of the tracks into a discreet object if that is desired for automation or other reasons.

There are other reasons why I might choose to use an object-based bed approach — similar to a standard bed — which does allow, in Nuendo, for assigning individual binaural render modes to each channel of a 7.1.2 bed.

Best i can think within Nuendo is try make:

-A mono group Channel for each surround postion: L. R. C etc, etc
-Place multi panner in correct position for each of these groups.
-Go to ADM control panel and using function make an object for each selected group and then choose an off/near/mid/far for each new group.
-then you can route your audio tracks to each position with its own binaural setting…
-However, you cannot route the created object groups to another BUS prior to the renderer.

So basically the near/mid/far settings being different between the different channels in your object-bed gives a different sense of space than if they are all the same, right?

Thanks for your idea. The current workaround for me is to just assign each zone FRONT, SIDE, REAR etc as a stereo object and send tracks to those as needed. I believe that is similar to what you mention although you are saying mono channels.

That is correct, overall just allows for flexibility in the case of utilizing on Object Bed mixing process.

Yeah, looks like that’s the best you’ll get. In hindsight, my idea using mono groups is actually not terribly practical in reality:-)
