Hi, looking for setup advice for live streaming from Nuendo to OBS in 5.1 surround. Mainly, how to route the 5.1 output from Nuendo into OBS correctly. Anyone done this? Any tips? Thanks in advance!
Hi, I use macOS and the Dolby External Renderer. I use the Dolby Audio Bridge (DAB) as an audio input into OBS. As an aside, there’s an OBS fork on GitHub that increases the number of channels from 8 to 16. So I can route the first 16 channels used by DAB to OBS. This OBS reference page helps with understanding the surround sound setup at that end of things. LFE needs special consideration in Nuendo if that channel is important to you (probably not audible on most consumer devices anyway). Given the 16 channel limitation, I really couldn’t use it the way I wanted, but it did work. And it doesn’t help if the video watchers are not equipped with the appropriate speaker setup. Before I go writing on and on with information that does not apply to you (probably have done so already), let me know if you use the external renderer and are on a Mac. I don’t know much about Windows or using the internal renderer.

Hi, and thank you so much for sharing your process. I’m ultimately interested in streaming live in 5.1 to YouTube Live, which is supposedly possible now, although it can only play back in 5.1 through the YT app in Apple TV, for example. I’m using an X32 as my main mixer, and I’m wanting to route outputs 1-8 of that mixer to the OBS. However OBS only sees my inputs 1-8, which is not what I want, and it means I have to use an alternate method to get my mix from Nuendo into OBS. When I’m using Nuendo I can only select one ASIO source, which is the X32. If I were to use DAB I won’t have my audio inputs available in Nuendo, so that breaks my live chain hopes. I am on a Mac, and could create a multi-driver with both the X32 and DAB, but my experiences with multi-driver setups like that gets weird and unreliable, at least when I tried doing it in the past.
I’m definitely interested to hear more about your routing process if you are able to stream your live performance directly to OBS in surround of any flavor. Thanks again!
You have gone further than I have, so I will bow out. I don’t have an X32 as an additional element in the chain. When I need virtual audio devices, I use Loopback but I don’t know how well it would work with the X32. I also didn’t even realize that YouTube offered 5.1, I had only heard the earlier announcement regarding YouTube TV. But you intrigued me so I did a very crude stream of a Nuendo project with test videos and surround sound to OBS and then streamed it live to YouTube. It seemed to work. I had to regenerate my RTMP stream key and configure OBS. But I only hear sound, as you said, when watching on my TV with a surround sound decoder in the sound bar.
Here’s what I streamed:
In the last minute in the above video I solo the bass manager to limit the channel output to the LFE.
And here is the encoding information shown on my soundbar. (No audio because I recorded my TV with my phone).
I think the type of streaming you are planning must be for hand-picked audiences only. I wish you luck on your explorations into new technical frontiers. You are definitely in the vanguard.
Thanks for trying this! I watched your test and unfortunately for me, it only came across as two channel. In truth I haven’t been testing other clips and don’t really know for sure that this is a real possibility. Maybe that’s the next step.
Edit: Okay, I did find some existing clips on YT that are encoded in 5.1 and are showing up that way on my system, so I know it’s a true 5.1 digital stream. I’m not going to give up on figuring out that voodoo they do.
I’m guessing here that OBS = Outside Broadcast System or similar - if not what does it refer to please?
I ask because I have been working in 5.1 with Nuendo ever since build 1.01 and have not run across this acronym as yet.
Scrapo that - found it.
It’s Open Broadcaster Software - it seems to be a free tool as well.
