N12 7.1.4 Surround Channel Order is STILL wrong

I’ll try to conclude here on the subject of the method affecting channels within the 7.1.4. framework.

  1. Nuendo, via its internal Renderer, is reliable for producing a Dolby Atmos ADM according to the standards (if, like me, you use the SoundID Reference as an insert in the Control room, remember to deactivate it to produce the ADM, and of course use the ADM creator export).

  2. For monitoring, at mix level, you don’t need to change anything in Nuendo, but you do need to invert the rears and sides in your interface, either physically or in software (which has no impact on rendering, of course). For my part, I have a UAD Apollo x16 and I invert the rear and sides in the software console matrix.

  3. If I input the ADM into the Dolby Atmos Renderer for listening, I invert the outputs of the Dolby Atmos Renderer (or remove the inversion from the UAD).

  4. If I enter the Dolby Atmos Renderer to make a re-renderer or MP4, or master with the Dolby Album, I don’t invert anything and leave the internal configuration as it is.

This is the method I’m currently using.

Thank you for this info Mute. I just got Sound ID reference and noticed I had to swap the rears & side channels for the display to correctly match how I wired my speakers. Is this was you did as well?

Also, it it necessary to disable SoundID in the control room insert? I thought this is was the control room was for: inserting plugins for monitoring only, therefore they do not print upon export.

I’m not sure about everything, but the principle I’m adopting after testing is not to touch Nuendo. So I don’t touch Sound ID, except to remove it (without fail) before exporting the ADM. Maybe what you’re doing is okay, because the Control Room (and its inserts) only affects monitoring. But I prefer my method, just to be on the safe side. That said, there are plenty of options, as long as logic is respected.

Let’s hope that Nuendo will one day help its users to do this simply, with explanations to match.

I do have the same setup as you but I don’t need to change anything once I have everything setup. You should not need to remove anything from the inserts in Control Room when rendering. I also have the external Dolby Renderer which I can use for playback of ADM’s but once it’s setup I never need to change it.

If you export via the ADM function (not the bounce, but the ADM creator) and you leave the SounID Reference, it will be in the chain, whereas it is only used for monitoring according to your listening room. That’s my understanding, but I can’t remember where I got that advice. In your opinion, it would be useless and Nuendo would ignore it anyway? It could be.

As for Dolby’s External Renderer, I think you’re right. If the interface channels are reversed, it doesn’t know it and will do its re-renders correctly anyway.

Thanks for the clarification. Hope to help some users.

If your room correction plugin is in the Control Room path and your Renderer plugin is on the output bus then how would CR affect your render?

And if they are in the same path - why are they in the same path?

Indeed Matthias, so they’re not on the same path, so there’s no need to disable it. You’re right and I thank you.

IRCAM Verb maps the channels wrong too.
Their support just answered and confirmed it.
“We’ll try to fix this in a next update”.
Great!

In the meantime you can put the mixer delay plugin below it and correct the routing until they fix it. I had to do this with the Penteo plugin.
