How do I add vst effects to the main audio output?

This might be a (very!) rare instance where you actually *want* to create a loop, through the Monitor and a Desktop audio source.

Put your FX on the Desktop source, and have that be the only thing that feeds the Output. Everything else only feeds the Monitor. Use the same device for both the Monitor and the Desktop source, and now that Desktop source becomes a Master bus. Just don't Monitor that one. :-)

However, if you're doing something that needs that, you might look at doing all of your audio work in a DAW instead, and piping the final result of that into OBS, as its *only* audio source to pass through unchanged.
 
Thanks for the reply.
Your solution might work for me but may be a bit of a nightmare. I stream motorsports races and would like to get more of a cinematic sound. Biggest problem is each of the classes we run (sprint cars, go karts, motorcycles, sxs, even tractor pulls have totally different requirements and vst adjustments for each track. I know I can set up different scene collections but I can see that being a nightmare.
Being I'm running main cam and audio from an open air crows nest isn't any help either.
I was afraid I might have to use a DAW as well cause I may need to have more than the 6 tracks too. I'm seeing a second puter for audio in my future
Maybe when I become a yt gazzilionaire, I get an audio guy to handle all that and suck the result in by ndi.

If you're buying hardware just for audio, you might look at some old physical consoles too. My favorite at the moment is the Behringer X32, which comes in practically 3 different sizes: full desk, half desk, and 19" rack. (the two half desk versions are far too similar for me to understand why they both exist, but anyway...) It's getting replaced by the Wing now, so if you look in the right place, you might be able to pick up a used one for cheap.

The tradeoff there (ignoring contaminants from an open-air crows nest at a motorsports event), is that the physical console is a fixed-function device that will always do only that job, the exact same way every time without needing security updates that might break things...in exchange for not being able to add functionality either. If what it does do is enough for you, then it will continue to do that forever. (as long as the faders hold out in a dirty environment)

And there's a smaller X-Air series, that is essentially an X32 with features deleted until it fit in a smaller chip. Remote control *only* for those, not an option like it is for the X32.

In both series - X32 and X-Air - the processing throughout each series is exactly the same, with the same internal channel count, etc. The only difference is the number of I/O and the number of faders. The other internal channels that you can't connect physically on the smaller ones, can still be used for other things. For example, you might have, say, 4 mics total and 4 different events. You can patch those 4 inputs to 4 internal channels each, and have different processing on each of those 16 internal channels, all set up and ready to switch to with just 2 mute-group buttons or group faders...

To get from one of those into OBS, you'll either need a short analog cord to a USB line input, or you'll need to set the USB interface to be 2 channels instead of the full count. OBS HATES many-channel audio devices!
If you go with the X-Air series, only the flagship, the XR18, has a USB interface. All of the smaller ones trade that for a flash drive jukebox that is too picky to be usable. In the X32, you get both, but in the X-Air, you only get one or the other. So I'd only consider the XR18, even if its I/O is overkill for what you're doing, or an X32 variant.

And of course, a DAW can do all of that too. It's just a matter of which platform you'd rather run on.

Thanks, I'll look into that as well

Actually it is not and it is a feature that has already been requested multiple times. It is why people were actually using OBS Music Edition but that his horribly outdated. There is great benefit of putting a compressor or limiter on the main audio. It evens your audio out a bit more and can greatly prevent clipping. For people that stream music (and there's quite a lot) it is very useful. I'm surprised this isn't implemented yet.

It would sure be nice if OBS's audio were actually usable in general. But it's not, and so my suggestion is a hack to get the desired functionality, even if it *is* a hack.

On the developers' side, it's not just a matter of adding features to make things work. It's such a pile of band-aids already, on top of an original good design for a single purpose, that it's just not maintainable anymore. So they're looking at what to replace the whole thing with, to make it both usable AND maintainable.

I would not expect any changes at all until they come out with that, and I would expect it to be completely different. Not compatible with the present version. So figure out what you can to get by on what there is now, and thoroughly document what you're *actually* trying to do (not the hacks that you're using to get there now), so that you can rebuild it from scratch when the new audio system finally comes out.
 
You could try Waves Playlist Rider and Wlm Loudness Meter, part of their Content Creators Toolkit. There are presets to even out audio for Youtube and others. You have to put them on each channel but it works pretty well.
