Reverb & Submixes in Unreal Engine!

Ever wondered how you could stand outside a tunnel, fire a gun into it and hear the bullet reverb without being in the tunnel? In the past, you'd use the Audio Volumes to trigger reverbs, but they'll only work when you're inside the volume!
Topics covered;
Reverbs on Audio Volumes
Setting up submix effects
Setting up soundclasses to be affected by Audio Volumes
Triggering based on listener position
Submix effects chains
Using this method, you can set up all manner of effects via submixes to use elements like convolution reverb and more to emulate wwise akportals, rooms, and the bleeding of reverbs from inside one space into the next!
Special thanks to Angie for sending in this video idea. If you've got a problem you think needs solving, chances are others do to! Send it in!

I'm new to UE and I'm trying to dynamically create audio volumes in C++ but had no success so far. It does not have to be an audio volume, it can be a custom solution. Your videos are helping, thank you.

Nice video, keep up the good work! What do you do when you have 3 different volumes in play? For example: Volume A is the outdoor reverb Volume B is a warehouse Volume C is an office trailer attached to the warehouse, but the trailer also opens up to the outdoors. So if you are listening in Volume B and play a sound in Volume C. But Volume B is only got listener inside(warehouse verb) and listener outside(outdoors verb) submix sends setup. The sound in Volume C then sends to the Outdoor verb and not the Volume C office verb. How do you get around that?

Awesome Video! just a quick question here. Let's say you have 3 sounds sources, voice, footsteps, and impact. If you wanted to set different send values for each sound sources to reverb submixs that are set in audio volume, how would you do that? Sound sources that have high frequency tend to louder reverbs, so i wanted to reduce only voices reverb sends.

Thanks a lot for the video! Is there any way we can use Audio Volumes to send the reverb to a Metasound? Seems like when applying the effect, it only affects Sound Cues and not Metasounds. Tried to find a setting for it but I can't make it work 😥

Iiinteresting. The setup I have here IS with a MetaSound, and not a soundcue, so it might have to do with the bus you're routing your MetaSound not being connected to your verbs!
