 Hey guys, welcome back to my YouTube channel Daniel Rosal here and we're going to be doing today tackling something a little bit complicated But I really wanted to make this video for a while because it's going to be pulling together. I think two really important Things for anyone who is trying to record better audio into OBS on a bunch of Linux Bear with the noise. Unfortunately, there is drilling going on in the background It's kind of ironic because if there's any any any video I needed to use a bit of noise suppression for it would be this one But it's gonna be way too complicated to show you the all these controls and also do them in real time as I'm recording So sorry for the drilling and also another good reason. I have these studio headphones on so What I want to do in today's video, I want to do two things I've just uploaded a video to YouTube in which I talk about pulse effects pulse effects is a super useful GUI it allows you to do equalization You'll you'll see a full frequency graph of your input stream and you'll get a lot of controls You'll get reverb denoising stereo tools a bunch way more stuff than probably most people would need But if you simply want to play around with different equalization presets Really really useful. So even if you're just kind of a casual OBS user like me It might be worse just checking out some of those to see if they can make your microphone sound better now Here's the connection to monitoring a while because I've done a video about monitoring I've done a video about pulse effects and here's why I want to do video about monitoring and pulse effects because When you're changing stuff settings in your microphone There's two approaches one you can change stuff record and listen. Hey, did that sound good? It's a very inefficient way to go about it. So that's why monitoring is useful listening to yourself as you record So if you're gonna be doing pulse effects changes, you probably want to be monitoring as well. So It's gonna get a little bit Tricky for me to keep this straight, but let's let's jump into my screen here. Okay Now I mentioned this in kind of every video, but I like to I'm gonna do it again here It's really important to think about the kind of what I call the cadence of your of the of the audio controls when you're recording OBS you have your pulse. Sorry your pulse audio GUI. It's launched by the by have you control That's this window here and this is like the master of the audio in In this kind of a sequence at least I don't do stuff with Jack or more complicated audio stuff But just using the basics in Ubuntu. This is kind of the master then you have in this configure lease Then you've got pulse effects sitting between between that as an intermediary in equalizer and then that passes down To the application layer. That's why I've dragged across my OBS studio mixer so that you can see that This is I have my this is a my this is the lab mic that you're listening to up the top here the mono off analog stereo I've applied a minus five DB. It's 81 percent and I can see impulse audio levels I'm getting recording this out or looking fairly. Okay. They're not clipping Repeking here at about minus To do do minus 14 or there about DB. So How do you monitor so by default in Ubuntu In have you control there's no button that says please monitor this audio stream. That would be super useful If there was if that was built into the GUI I guess it's not because monitoring is kind of an obscure use case for most everyday users and If every time you plugged in a microphone by default at monitor that would drive most people crazy because you'd hear yourself so The the way I know to do it is by using this command and I'm gonna just it's the it's this one here So just to talk through this command for a second PAC TL load module okay with the hyphen and then it's module loop back and then to turn off the Monitoring loop and that's what it is. It's a loop. Here's my microphone It's gonna be recording and we're also gonna be creating an output stream that's gonna loop into my headphones So it's creating a sort of circle So module loop back and then it's module unload. Sorry. It's unload module module loop back And that will stop the monitoring. So I'm gonna turn on The module and now it's gonna get kind of distracting So I'm gonna actually take these off because I can hear myself And it's super hard to concentrate as you hear yourself in the middle latency So now I can hear my microphone now. There's actually two microphones Recording here as you can see one of them is a built-in microphone of The webcam the other one is the the microphone. I want to monitor which is the mohono. So how do you? specify which microphone you want to use for the loop back so This probably is smarter way to do it And if you know that please leave a comment for the for the more intelligent way the kind of hacky workaround I figured out is to set the microphone you want to monitor as the fallback And that'll that'll give it primacy when it comes to Monitoring so I have my mohono set as fallback by ticking on this green Icon here and that that's what it's looping into these headphones here. Yep still going Okay, so we are now monitoring. So this is kind of the first stage of the process done now Let's go into the the pulse effects Okay, so now I've got my pulse effects and what you can see here. This is pretty this is actually kind of where Honestly, we could just end the video here because This is you're basically applying the The pulse effects into your loop back channel now. I'm on the output side of pulse effects I'm just going to drag it down so you can see it. There is an input side as well. So If I was recording if I was using this with OBS, I've said before I get two OBS channels and pulse effects I'm not sure why I'd be applying the first one and In order to monitor what was going on there There is a few options here. So firstly You've got two approaches that you could use the first is as follows if you want to apply Changes to your microphone. You can do it here Set up your settings and then apply them again on the input side of pulse effects So let me just pop on these microphone these headphones and I'm putting on let's say base enhancer and now I've got Some base enhancement going on changing a few settings Let's say Reverberation to delay time delay time so This is one way you're going about it You can play around with the loop back channel directly Another way that you can do it here is and then apply those same effects over on the input side of pulse effects There is one more way you can do it is going to get a slight bit more slightly complicated now If you look at your pulse effects your playback stream You can put this into the loop back channel and listen to it there. So you can actually be directly Let me just explain this one a little bit more a little bit more carefully You can be directly applying to your your settings on the microphone into OBS and You can be if you look now at our input devices We're going to be having OBS in my recording Here and you can direct that to the your headphones
