 Hi guys, welcome back to my youtube channel. This is Daniel Rosal here in Jerusalem quick video regarding the Subject of monitoring audio in a bunch of Linux if you want to start monitoring then how do you do that? So before I get into that I wanted to just say a couple of words about why monitoring is so useful Monitoring audio you might want to do it if you are recording something whether that's you're recording a you know a Podcast or you're recording a screen Cast with an audio component or just about anything else you might want to record on a computer and Those kind of situations. It's good to monitor your audio To hear what you sound like before you start recording. So like most things in life Prevention is better than cure. So if you can fix your audio levels fix your audio issues before You record then it's better than having to go into post-production Whether you're post whether that post-production workflow is for audio or video and trying to do things like fix his is or fix problems and That's another issue actually yesterday when I was recording some of these videos I was getting a tiny bit of his from the USB microphones and it turned out that my levels were a tiny bit too high In my pulse audio and you're just looking at that now in fact if I just Diminish diminish my myself here a little bit but you know, it would have been better to basically go in and Just hear what that was what sounding like essentially so Before recording and the way you do that is you just can get the monitoring running now to be transparent Not an expert. I record these videos for My own use actually so a lot of the times I will forget how to do something because Linux is complicated a bunch of Audio is complicated and I like to have these videos that I can refer back to and say, oh, yeah This is how I set that up. So for Monitoring, it's a pretty simple command that you can just put into a terminal and that will load that into pulse audio And then you will guess you will see after this magic happens and I'm actually just gonna go ahead and I'm going to go ahead and mute The channels I'm not using just to be attempt to be safe So you will see the channel now actually that was bad that was a bad idea because If I do that then you're not going to see the channel working So the channel you're looking at here is the loop back now. I'm going to have to stop speaking because I This is going to get into the audio track for it for here. So I'm just going to stop and You can see the track is open now. That's the monitoring channel for the webcam microphone there as a playback device Now what you need to do here basically is or what you how you would use this is as you can see I have the I have both microphones being picked up now the reason I said I'm not an expert and all that which is for sure true is what I haven't figured out yet about this is How to create the right loop back so in this case I have this microphone the podcasting mic And I also have a microphone that I don't I'm not using I'm not recording into I wouldn't care about and that's the built-in microphone on this webcam the c930e and when I put that command in the Monitoring channel that it gave me was a loop back for the webcam and not a loop back for the Maono now if I plug out the webcam I Will guess a loop back for them Oh, no, but if I need the webcam to record myself and I want to monitor The the track from the podcasting audio. I haven't yet figured out a way to do that But I'm sure I will figure that out today. Hopefully so basically once you've opened your monitoring channel that's open the one for the Webcam again Loop back for the webcam. Let's unmute that now. We can see we have levels going for that No, what you can do is just put on your monitoring headphones And now I can hear myself there's a bit of latency, but I can hear myself in them in the headphones I'm just gonna turn that off. So basically That's pretty much what there is you just want to make sure that the loop back channels going where you want it to go so I went for built-in audio stereo if I went for the HDMI audio that the monitor would be coming through my Laptop sorry through my desktop monitor that The LCD monitor that is which wouldn't be where I'd want it to go And this would be the microphone which wouldn't be useful. So I had to change that Unmute that and then I can listen to with headphones or whatever That's the final thing I would say is that this is if you are Doing monitoring then you might want to use headphones intended for this purpose To that I'm aware of are IEMs in ear monitors such as eddy modics. These are basically earbuds That you know the earbuds you'd pick up in a high-street retail store like skull candy, but they're kind of different They are They're really good at passive noise isolation. So I actually use them for blocking out I don't noise because I am noise sensitive But they also Reproduce the audio well and if you think about what what these two features would bring together will basically if you are trying to listen to your own Mic feed or you try and listen to a producer in a production environment like you're a musician or whatever Then that's where these things. That's what they're designed to do take in a monitor feed and put it into the Hardware intended for that purpose Kind of a hacky use is to use them for blocking out noise, but that's what they're really intended for second thing is studio headphones. So I picked up these audio technicas recently in the US and These are studio headphones. They're basically intended to reproduce sound authentically From from my understanding. So, you know a lot of headphones The goal is to make the sound sound good So when you're watching a movie or whatever that sounds all the tones are nicely balanced and the objective for these is more to So that you'll actually hear the audio including the flaws So you as an editor can fix it whether you're editing editing audio or audio with video So that is basically it to recap. Oh final thing I wanted to say about pulse audio here is that What you can do is you have if you open up the advanced pain you will get latency So I mentioned that when I put these on I was getting latency in the in the loop back feed Now if you want to try to correct that there is two ways one you could add latency to the Microphone that you're monitoring. I don't know if this is considered a poor practice or not But that that's one way I was playing around with and the second way is you could configure the latency On the loop back you can't actually do that here. So scratch scratch that scratch that That's basically What I figured out so far about monitoring audio. I'm just gonna open this and the loop back channel and Output devices And input devices So that's it. Thanks for watching.
