UE4 Reverb Basics Walkthrough

- A basic walk-through of setting up reverb in UE4 4.25. Both 2D and 3D reverb.
At the posting of this video, I am a Technical Sound Designer working at Epic Games on the Unreal Audio Engine team.
Some notes/errata:
- The Volume parameter relating to Reverb on the World Settings, Audio Volume Settings, and on the Blueprint Function API refer to a scalar applied to the Reverb Output not Input. A subtle distinction.
- The stat command I forgot to mention is: stat soundreverb
- The reason you will want to tag reverb settings applied via Blueprints is that you can have multiple settings at once, but only the highest priority one will be used. In this way you can have essentially an array of active reverb settings and selectively remove them.
- In the orthogonal overhead view, I was able to measure the distance from one point to another by pressing down and holding the middle-mouse button (or in my case, my mouse wheel) while dragging across the space. Very handy when figuring out Attenuation Settings.
Thanks a log, I was struggle with the fact that my Camera wasn't in the volume until this video. Thanks :-)
The reverb tutorial that was desperately needed on TH-cam, thanks!
Such a useful guide, thank you for sharing. I was wondering how to do reverb for a while and you taught me the basics.
Thank you for taking the time to go through this!
I have known so much about sounds in UE4.
Thanks a lot!
You made a perfect tutorial! You are great!
Thank you so much Dan, this was invaluable, I learnt a lot!!
Amazing stuff! Thank you for a high quality explanation Dan!
Thank You!
THANKS !!!
Great Tutorial! Thanks!
Glad it was helpful!
Thanks for the video. "stat SoundReverb" is deprecated, and "au.Debug.SoundReverb" doesn't work in UE 5.11. To get the debug use "au.Debug.SoundReverb 1 -AllViews"
I think I haven't missed any steps but when I place the Audio Volume, set it up as you did and hit play at 15:10 in the video, the level reverb stays on, though debug does show the volume reverb becomes active when I enter it. (Edit: I missed at 14:53 you cleared the ReverbEffect from the World Settings. Now it works.)
Still cannot figure out how to make the inside of my room quieter than the outside. (Edit: Eureka! When i go into my building the outside sounds get quieter. In Sound Class, under Routing, check Apply Ambient Volumes, then adjust settings in the Audio Volume placed in the World!)
Thanks again for this video!
very helpful, thanks for taking the time to make this. Are traces used at all to evaluate the environment? Is that something configurable?
Yeah, the Attenuation settings, under the Occlusion category, offer controls for tracing - like the channel (Visibility, World Static, etc.), to use complex or simple collision, or even to assign a custom Occlusion plugin. Kinda late reply, but several liked the question, so thought might as well offer ideas.
Fantastic video! Just one question about this stuff. So if I define my reverb effect setting in an audio volume that I scale to my level, then I all I would need to do to hear it is ensure that my attenuation asset attached to whatever audio that's playing has reverb send settings turned on in it, correct? Or is there another step to that that I missed?
Not sure what you're asking. If you followed all the steps laid out in my video, then you would have missed no steps.
@@DanReynoldsAudio Okay so imagine: Reverb Effect > attached to Audio Volume actor in the scene
Sound wave that exists in the project somewhere > attached to attenuation data asset that has reverb send values defined in it
As long as I am inside of that audio volume, I should be hearing the reverb values I defined, correct:?
@@xcryosonx If you followed every one of my steps, if you literally did everything in the video, then it should work. If you skipped a step, or if you did not do everything in my example, then it might not work.
So as an exercise, watch the video, and then enumerate each of the steps, starting with 2D reverb, starting with using World Settings instead of Audio Volumes. Exactly as I have done in the video. I will examine your steps then and see if you've skipped something. But the question you're asking me is only part of the steps involved, so the short and unhelpful answer is yes, it should work, but I don't know what you've skipped or omitted because you didn't even list everything that had to be done in the video.
This suggests that you've omitted it because it was obvious, in which case of course it should work, OR you've omitted it because you've skipped it, in which case of course it should not work.
All the Audio Volume does is set the Reverb Settings and modify the Volume Output on the reverb effect. If you have no reverb effect, the volume output is 0. So putting the Listener into the volume activates the referenced settings (so the parameters on the reverb change) and that includes the volume.
What of your sound class? Why are you using a Volume at all if you want it in affect throughout the entire level? What are your send levels? What are your volume settings? What about your soundreverb debug? Does it show an active reverb setting? What about the gain settings on the reverb preset? Are they reasonable? How far away is your sound? Is it out of range? Too quiet?
so i was trying to use audio volumes and i ran into two big problems. first: even though i made my sound cues play with reverb, no matter how long i set the decay time, the reverb was still too short and nothing was changing at all. second problem: i am completely unable to affect sounds of steps of my character. steps are added as notifies into annimation and i even created attenuation for all sounds. nothing. sounds of steps are not reacting to reverb zone at all. i dont understand this, i made all the steps and still got unsatisfying to zero results. please help.
What are the SoundClass settings for your Footsteps?
@@DanReynoldsAudio honestly, i didnt create any SoundClass in this particular project, because i saw people doing it completely without it. only audioVolume box and a reverb zone. i am working in unreal 4.26. is it important to set things up in SoundClass as well? its kinda hard to recognize, what is setting the reverb up - settings of the reverb itself? settings of the audioVolume box? settings that are in attenuation? what overrides what? what is the priority for uneral, if i setup reverb differently than attenuation? its just so chaotic!...
@@tmoblak I go over the required SoundClass settings for 3D and 2D reverb sends in the video.
Alternatively, you can have a custom Submix and use Sends to do your own thing and not use the legacy reverb system.
