Dolby renderer object order

ok heres one I probably wont get an answer to, but I’m confused why the renderer in cubase has bed object 5 6 7 and 8 one way, and the wavelab dolby objects are in a different order, I thought the renderer objects would be standard to each renderer,

That’s a bed though, right? Not objects.

So search for a thread on surrounds being reversed. At least one thread exists.

hi MattiasNYC, that was a useful idea, the search did bring up another thread where the discussion says that Steinbergs order is different from Dolbys order, no discussion of why, but it has been observed,

I actually think a justification for it was in one of the threads. Maybe something about expanding the system from 5.1 and what that entails or whatever. I remember thinking it was logical in and by itself.

i got nothing that gave me any real clarity to the difference, there was some discussion on something for monitoring, but for me personally it seemed confusing because as I created a example of bed sounds in cubase the left and right objects played 7 and 8 then when I loaded them into Wavlab those object were 5 and 6, made me want some clarity on why that was changing because I assumed there would just be one way standard for all of it..

Yeah, sorry, I didn’t realize this was in the WaveLab section of the forum. I’m so used to reading about Dolby in the Nuendo section. No idea why it’s different. It’s inconsistent for sure, and interesting (that it is inconsistent).

They should streamline it across apps.

WaveLab shows the bed channels in the Dolby Atmos standard, which is actually the SMPTE standard.
Cubase shows the bed channels in the VST-3 standard, which is based on another standard (I don’t know which one exactly because there are several other standards, but at least, the VST standard maps partially to the Microsoft RIFF standard).

What is important is that when you play the channels, they reach the right speakers! And for that, the Dolby Atmos file must be written in the proper order. This is the responsibility of the audio application.

What is also important is that when a VST-3 surround plugins gets audio data, the channels are in the proper VST order. This is the responsibility of the audio application.

All that requires some channel swapping at some stage for Cubase and WaveLab. I know that very well because this was a bit of a headache during development. Even the acronyms are not uniform (this is why WaveLab provides tooltips, for example, in the bed track headers).

Note that when rendering a surround audio file from an Atmos montage, WaveLabs gives you the choice between the RIFF format (recommended in general) and the SMPTF format.

I suspect the above will be referenced by Nuendoites.

The compartmentalization within Steinberg is odd. Either that or N15 will see this order reversed.

ok thanks PG , , for at least some basic clarification
