TL;DR

Tutorial: Using NVIDIA noise suppression in OBS for cleaner pinball streaming audio

Summary

George from Don't Panic Flip provides a technical tutorial on implementing NVIDIA noise suppression in OBS to reduce background noise from pinball machines during streaming. The video walks through downloading RTX Voice drivers, disabling Windows 11 GPU scheduling to prevent OBS crashes, and adding the noise suppression filter to audio inputs, demonstrating the audio quality improvement with before/after examples.

Key Claims

Pinball streams have significant background noise from flippers and ball movement that degrades audio quality
high confidence · George (Don't Panic Flip host), stated as motivation for implementing noise suppression technology
NVIDIA's noise suppression filter can be adjusted from 0-100% to control how much background noise is removed
high confidence · George demonstrated filter settings at 100% and 69% removal during the tutorial
Windows 11 GPU scheduling (hardware accelerated GPU scheduling) must be disabled to prevent OBS crashes when using NVIDIA noise suppression
high confidence · George identified this as a critical configuration step, warning 'OBS is gonna crash' if enabled
Don't Panic Flip streams live three days a week: Monday, Tuesday, and Thursday from 10 p.m. to midnight Mountain Time
high confidence · George stated broadcast schedule directly

Hey everyone, my name is George and I run the show Don't Panic Flip and recently we have tried to improve the audio quality of a pinball stream. Now, pinball streams are interesting in that there is a lot of background noise. Background noise, in this case, typically being the sound of flippers and the pinball moving around. So not only have I made upgrades to the equipment I have and some of the mixing, but we've actually started working with NVIDIA's new background sound removal software. They have some drivers for this, and then there's a bar as it integrates with OBS that allows you to add a filter and adjust that up and down. And I wanted to take a few minutes to explain how anyone could implement this as long as they have an NVIDIA video card. But first, let's take a look at what your stream could sound like if you had a lot of background noise and you either removed all the background, eliminated none of the background, or just tried to eliminate some of the background. Would you like to hear what the flippers sound like without any suppression? This would be like what it was like a month ago before I enabled the NVIDIA stuff.

So, I'm going to talk. Hello and welcome My name is Don Panic Flip Actually my name is George The name of this stream is Don Panic Flip And now while I talking right now I am flipping the hack out of this pinball machine Hopefully you can see that. While I was talking, could you hear the flippers at all in the background?

Now that was while I was talking. When I'm not talking, can you hear these flippers? Anything? because I can't tell. I don't have feedback at this point, but that was with a filter set to 100% of the background noise removed. Now it's at 69. All right, it's at 69. Now I'm going to flip.

I can assure you it's very loud to me physically here. Can I do the same with my kids? Okay. Okay, so now you've seen what the benefits are, the potential benefits of using the NVIDIA noise suppression technology in OBS. There's three parts moving forward to actually using this. The first is downloading the appropriate software and getting that installed. I'm going to walk you through that. Second is there is a setting in Microsoft Windows, assuming you're using Windows 10 or Windows 11. I guess it's Windows 11 at this point, where OBS would crash if a particular setting wasn't disabled that had to do with OS level 3D graphics being enabled. And I going to walk you through where that is in Windows 11 and how to turn that off And then finally how do you go into OBS and add the filter after you have installed the drivers and disabled this So that way, when you first turn it on, you don't end up crashing OBS and have to restart it. So let's get going.

So first things first, I'm going to need you to navigate to Google, and I want you to search for Download NVIDIA Noise Suppression. That's going to bring you the very first search response is a GeForce web page, and you can see I'm scrolling down here. Go to Download RTX Voice. That's going to be a really quick download. I want to say it's 250 megabytes, and you'll want to install that. Go through. It's a standard installation. Nothing too crazy there.

Next up, I need you to open Settings in Windows 11. and as you can see I'm scrolling down here I want you to select display and from the display menu I want you to scroll down and choose graphics from graphics I need you to select up at the top the that what I just selected and then finally it's the hardware accelerated GPU scheduling this was enabled for me when I first started disable it because if it's enabled OBS is gonna crash. Great. Now we're here in OBS. You can see I have quite a few scenes. I use nested scenes I scrolling down and I just gonna choose my actual camera scene where I have my audio input I going to add a filter to my audio input by right on the source

And you can't see the right-click menu in the capture. None of this is being captured right now because it's in a different screen. Huh. I'm going to have to undo this.

Well, that's great. So there you go. I hope you enjoyed this walkthrough, not only showing how NVIDIA's noise suppression can be used to help improve the audio quality of your streams via pinball or something else where you have a decent amount of background noise, but I hope things were straightforward and simple. And if you like the video, make sure to hit the subscribe button. Feel free to join us on Twitch. We're live three days a week. That's Monday, Tuesday, and Thursday from 10 o'clock p.m. Mountain Time until midnight, maybe sometimes a little bit later, maybe sometimes a little bit earlier. It just depends on the day. But that schedule is pretty consistent. And feel free to hit up the website. You can go to DontPanicFlip.com where we have articles associated with a lot of these streaming tech how-tos. I just want to make sure I feel like everybody out there can learn and do some of these things that aren't that difficult. They're not technically difficult. We just need to figure out how to do it and create the directions to make it easy for everyone else to do it. Thanks.
