(LIVE) Livestream Audio Hijack Demonstration

okay hello hello if you're here say hello in the chat introduce yourself tell us who you are and what kind of um content creation you do wow right as i started alive i got that little that little tickle in the throat something just just some little fuzz ball right in my throat so uh pardon me that was super exciting a really fun way to to start everything i felt i was like uh oh no i can't power through this for 30 minutes i need to take a sip of something so hello everybody um introduce yourself in the chat i think what i posted a minute ago was introduce yourself in the chat if you're here um obviously if you're not here don't introduce yourself in the chat but thanks for being here i'm brian miller for those of you who don't know me although i can't imagine if you're watching this you don't already know me this is the the audio for content creators channel and i know that just over the last few weeks i've had a lot of people reach out to me and say hey i've been following your main channel on youtube for ages i had no idea this was here yes that has been my primary uh difficulty uh getting people to realize that i've got this new dedicated channel just for just for audio um but the the beauty of what we're doing right now is i want to show you live a tool that i'm using live right now for live streaming so i want to demonstrate a new piece of software that i well it's not new i guess it's been around forever but the latest iteration i just discovered i purchased it and i've only used it for a week or so but it's already just a freaking miracle uh for me and you're hearing it right now it's a program called audio hijack and essentially what it does is it allows you to do real-time effects processing for audio uh which you can use to record locally on your computer or you can use with live streaming or content creation really anything you want any audio that you can hear on your computer you can capture and send to basically anywhere else and so i'm going to do a screen share and let's see share your entire screen yes and we'll go over here and i just want to make sure yeah you we got the uh we got the infinite recursion thing going on here so let me shift over to here and you should be seeing the audio hijack uh the the entire box right now um actually you know i wonder can i move this over i want to see if there's a way that i can i can show this to you now that's going to get weird weird and recursive okay i can't actually see the chat box while i'm staring at the screen so toss stuff into the chat ask questions i will go check i'll have to switch windows to check on that every so often because i don't have two different monitors in front of me right now but what you're looking at is audio hijack it is a paid piece of software i think it was only 40 bucks i didn't really pay any attention and which tells you it wasn't very expensive i wasn't paying attention to the price when i bought it i think it was 30 or 40 bucks so for something that is this cheap you're not going to believe how incredible it is and you're seeing it in action and you're hearing it in action right now so let me actually just make this screen maximum size for you and you can go ahead and see what we've got going on here you get to take any input device so you can go ahead and decide what input device you want to choose so you might have a usb microphone plugged in you might have uh just a built-in microphone which you shouldn't be using but maybe that's all you have um anything here right my webcam has a mic built in i have all these other my rode videomic ntg is plugged in via usb right now although i'm not using it uh i've got this as my audiobox 44 which is my presonus four channel audio interface that i always use so that's what my input source is and then what you do is you go over here to the right side and you see that it comes with so let me just show you it comes with sources outputs built-in effects some advanced stuff and some metering everything down here audio unit effects these are all the ones that i've paid for over the years these are all my plugins that i use for doing audio engineering we're not going to talk about those right now because everything you need to do real-time effects processing either comes built into this or you can go get a free version of any of those plug-ins um on your own and they would show up down here under audio unit effects so what am i doing to process my audio in real time just to give you a sense of what this entire thing looks like here we've got the input device sorry i couldn't tell if that i i was hearing there was a plane going by overhead and i couldn't tell if that was some weird noise i was getting from within the audio signal itself or if it was actually coming from uh from outside anyway it's outside let me just swipe back check the box no comments no questions okay good to do good deal so here we've got the input device we've got the audiobox 44 vsl then what i've done is i've dragged a denoising software that i have uh this is this is a expensive high priced one but as you can see right over here there is a denoising software that i turn that off there's a denoising plug-in that comes right with audio hijack that you could use here and you'll notice what happened i dragged it and i can put it wherever i want in the chain and the beauty is you can see exactly what it's doing and where it's going and you can completely visualize your entire audio chain i think this is really really really helpful for people who are uh who who are visual learners or who just don't have a lot of experience with audio and need a way to visually see what's going on so i'm going from the audio box into a denoising software which is probably why you didn't hear the plane going by overhead then i'm going into an eq plug-in again these are all all the ones i'm using are ones that i own and i paid for but you've got over here you've got a 10-band eq that you could be using right here and you can just mess with your eq right here right and then i'm going into a compressor now this compression that compressor is the only thing a compressor is the only thing that i don't uh see built in to the software uh to audio hijack but there are lots of free plug-ins that you can go get that are compression plug-ins that you could use if you wanted to so uh so i've got my compressor here so it's evening out my voice overall by doing three to five decibels of gain reduction if i got really loud you see would spike all the way up to six decibels of gain reduction and that's keeping my voice at a nice even volume and then i have a limiter right here this is a brick wall that i have at the end of my chain here which you'll see that i have my output ceiling set to -1.5 db normally i'd only set this to 0.5 or 0.2 db just to avoid any digital clipping but i've got it set to minus 1.5 because you never really know what these streaming softwares are doing to your audio they have their own processing like i'm in stream yard right now and it does i've i've clicked the button that says disable stream yard processing like don't do any of your own processing but you never really know what they're doing behind the scenes and so in case they're doing any additional leveling at the end i've got this set to minus 1.5 db so you can see what's happening is if i get really loud you see the red over here the attenuation that's how much you're uh doing gain reduction there is no way that this is able to get over minus 1.5 db because i've got the ceiling set on my limiter and if i pull up my audio meters you'll see no matter how loud i get it will not go above minus 1.5 db and finally you get to select the output device where do you want to send this entire audio chain and i'm sending it to something called loopback which we'll talk about a little bit later but that is a virtual audio source a virtual audio in and out source which is how i'm sending this through stream yard in real time loot back is another paid piece of software but there's a free one called sound flower that i've used for years and years um and and i only picked up loopback uh literally this morning and i'm just using it because it's designed by the same company that makes audio hijack so i'm just gonna zoom back over here make sure there's no okay checking in the chat nothing in the chat okay so uh now what i want to do is i want to actually turn off everything show you what it sounds like let you listen to what it sounds like then turn it all back on and you can hear exactly what this is doing and then i'll talk about the recorder over here and some other cool things in a second so i'm going to turn off everything so now you are hearing the actual audio coming directly from my mic into the computer and going into stream yard uh in fact i mean let's let's be fair i'm also um before i go into the computer this mic is going into a hardware processor that's got a tiny bit of compression a little bit of eq so even this isn't totally raw but that's just to avoid clipping my uh my audio box my interface on the way in so right now you're hearing what the computer is getting completely uh raw and then if i turn on all of these now you're hearing the edited processed sound that you would get if if you were doing this in post and you knew what you were doing but i get to do it here live in real time for streaming or as a guest on a podcast or a guest on someone else's live stream which is fantastic you'll see that there are all kinds of really really clever features here there's a an input switch there's a ducking you can duck one audio signal under another in other words if you were streaming and like you're a gamer and you've got some music on you could have this ducking set so that every time you started talking it automatically lowered the volume of the music you had playing however much you wanted while you were talking and it automatically brings up the music when you're done talking de-noise you would use in place of this denoising d-hum if you've got some hum going on from some wireless interference that's great d-click i should probably actually have this on um so d-click is great because uh i'm using a very very sensitive um oh i can make this big again i'm using a very very sensitive condenser microphone which means all those awful mouth noises the clicks that you get from your mouth which can be alleviated by having lots of that's coffee you should be having lots of water um if you've got those clicks in theory this d click if you set the threshold right we'll get rid of some of the most uh egregious ones and make it a more pleasing experience for you for the listener so i'm going to turn that off right now and over here you've got your 10 band eq you've got relative balance of stereo channels bass and treble uh you've got a low pass filter which you should always always always have on if you have a mic the only reason i don't have that over here is because i'm doing a high pass filter right here in my eq mono enhancer enriched the mono audio with a stereo sound pan you know left or right so actually i could i could take right here i just realized that the recorder was also sending to the output so hopefully it was not uh creating too big of a problem while i was doing that um you want to make sure this recorder if you're using a recorder it doesn't send the recording through your output as well so i apologize i didn't realize that was happening a second ago but watch this if you've got headphones on i can pan all the way to the left i can pan my voice all the way to the right i can bring myself right back to the center so you can actually take different sources and put some of them over on the left and some of them over on the right you know different things like that so let me give you a quick idea of how you actually might use another input source so let's say i wanted to add an input and i want it come on come on let's see there we go i only want it to be going to the output i don't want this new input source to be hitting any of this stuff it's just going to go to the output and i'm going to select itunes and to avoid any copyright strikes right now i'm going to play one of my own songs which is off of my brand new let's go back over here off of my brand new album which is coming out soon i'll talk about that in a little bit i've got a an 80s concept album inspired a progressive rock inspired hard rock album coming out that we've been working on for about four years it's passion project it's coming out real soon so if i wanted to show you let's see i've got itunes set and here i can go ahead and click on the title track from this album called when the world [Music] before we thought we knew it all young deity would get called they said fill in the world of mass reality with a little touch of insanity for me he said about his [Music] ability [Music] so that is just uh something that you can do there so what i was able to do there is obviously pass that itunes audio directly through the same output source that um the same virtual audio source that stream yard is currently using as the input source which means i'm able to play you something and if i wanted i could have set up ducking like i said so that the if i had started talking over it the music would have come down as i was talking come back up i didn't try to do that in real time because i was worried that i was going to accidentally do something wrong in the middle of this live stream and i didn't want to screw it up you would set this up in advance and test it and make sure that it that it works so um that is that's what's going on there in in audio hijack so i'm going to take any questions now for the next 15 minutes about real-time effects processing using audio hijack itself about how to you saw for a second that i was using that uh that screen called a loop back uh which was actually here let me let me actually show you let me see if i can show you that uh that loop back so i'm gonna do a a new screen share and only only show that uh window why can't let's see here we go i'm going to show you the loopback screen hello hank good to see you nice of you to be here so all right so now you should be looking at the loop back screen so loopback is a is a fairly pricey i think it's 130 140 bucks something like that it's a fairly pricey piece of software much more so than audio hijacking it and what's weird is that it looks simpler i think maybe it looks simpler uh but the the beauty the beauty of this is that i'm gonna turn off itunes there the beauty of this is that it allows you to basically route your internal audio however you want and create a virtual audio in outsource so essentially what i'm doing is stream yard i've set stream yard let me actually i just noticed that the logo is probably in the way up there so what i've done is i've set stream yard to uh use loopback as its microphone right as the microphone for loopback and uh as the microphone for for streamyard it's using loopback so what is it getting well you can actually see the meters pegging right here and the beauty of this just like audio hijack from the same company is that you can visually follow your internal audio chain and you can mess with it and move it around however you want so this pass-through what i'm doing here is i'm actually sending the audio from audio hijack here i'm sending it via this this is the the kind of proprietary thing that loopback has which is called passthrough and you can take any audio source anywhere on your computer and set the output to pass through and if you set the output to passthrough it's going to show up here at the moment the only thing set to it is the audio hijack processing chain that i'm using right now that i'm i'm speaking with so that's showing up right here and as you can see i've got it routed you can just follow right i can click this you can follow the channel 1 channel 2 which of course at the moment is identical because i'm just got a mono source that's being duplicated but channel 1 and channel 2 are going straight up here into this channel one channel two and that is my main output okay so that's the main output now what i was doing a minute ago with uh with itunes is i had another channel now you can you can add channels as much as you want down here you can just keep adding different output channels and what i wanted to do is i wanted to have itunes i wanted to hear it but i didn't want to monitor it okay i wanted to hear it in my headphones but i didn't want to monitor it and that's where the software is tricky but makes something that is almost impossible to do otherwise much much simpler which is i took itunes and i routed it into this channel three and four and then i routed channel three and four over here back to my audio box which is where my headphones are plugged into my headphones are coming out of my digital interface my audio box and what i wanted is i didn't want to send the itunes signal directly into the main output for stream yard because stream yard was already getting that itunes output from audio hijack okay so follow this this pass through that's audio hijack audio hijack had my processed voice and itunes and they were both going into this which means the channel 1 and 2 output that stream yard is getting this is what stream yard is using this right here that already had itunes built in so if itunes was also going into this output right here you'd be getting itunes twice you'd be getting a duplicate of it and i didn't want that so i s but the problem is i still wanted to hear what the music was coming from itunes because i wanted to be able to you know i need to hear what you're hearing and so in order to do that i took itunes here in loopback i routed that audio to a different channel that's that's separate from the one that you're getting because you're already getting itunes and i just routed that out back to the audio box and for the same reason i'm routing my own um i'm i'm not having my voice come back out to the audio box notice that my voice is going here it's getting processed and audio hijacked so audio hijacks off here somewhere it goes in here and it shows up in your output but the only thing that's coming back to the audio box is the internal the internal computer right the internal computer sounds i didn't want my voice coming back because of the latency because if i go in from a microphone i go into the digital interface it goes into the computer it hits audio hijack it hits four plugins in a row then goes back to the digital interface and back to my headphones that round trip is about half a second it's a long time and what you end up hearing is an echo of yourself in your own headphones so i don't want to hear myself coming back out into the audio box but i still want to hear the computer's audio just without me does that make sense that is what this this software which is somewhat expensive because now i'm sorry i guess you're hopefully starting to understand why it's expensive it's complicated you'd have a real trouble doing this on your own and that is what this allows me to do is have different channels outputting to different places so you can monitor your audio differently from what the audience is actually hearing if you're live streaming or recording or anything like that so that is loopback and as you can see here because i do tutorials obviously i do audio tutorials where i need to record myself talking and i also need the internal audio of what i'm showing you right this is studio on my audio software i have this routed also going into the output because i do want uh whoever's listening on the other side you to be able to hear what i'm doing but i also have it coming over here and heading back to my monitors to my headphones because i need to hear i need to hear what i'm doing in the audio software as well if i wasn't routing to channels three and four which is going to my audio box then you would be hearing what i was doing in studio one but i wouldn't be hearing it it would just can be completely deaf to what i was doing which would make it impossible to actually demo anything for you so that is uh that's just a little demonstration of audio hijack actually you know what let me let me go back to audio hijack for a second to show you something uh to show you something else uh i'm just give me a second and stream yard here to shift this around so okay so now we are back in audio hijack and i wanted to show you over here you've got a recorder option oh and by the way you can capture all system audio in one click right here i could drag this in somewhere into this chain right probably probably nowhere in this chain actually i would probably drag system audio like over here and then system audio would be also going to you which means right now if i got a notification anywhere inside my own software you would hear the same thing that i'm hearing in fact if i do i wonder if i use my my um speaker volume up and down do you hear the clicks are you hearing the are you hearing that i think you should be because i think if you're getting if you're getting system audio it should in theory be capturing um every single noise that's being made i'd be curious to know uh let me know in the uh in the chat if you actually did hear those little clicks but so you can capture your whole system audio and again send it here and this output device is going to loop back like i showed you earlier but here's the cool thing so over here you've got a recorder you can see it right over here and i've got the recorder only recording the input uh chain for my microphone so i've got my entire microphone chain here and it's recording here so i'm i'm not recording the end i'm not recording system audio you can see that i'm only recording this and uh i can't change these settings while it's in the middle of recording but you can see just how many options you get and i am currently recording a high quality wave at 24 bit and 48 uh 48 kilohertz which is fantastic you can set all of your different file limits you can and you can automatically trigger recordings as well you can actually have it set to start recording at a certain time and so for those of you paying attention what that means is that you can use audio hijack to record any sound on your computer so you know if you wanted to uh you shouldn't because it's illegal but if you wanted to you could obviously record any song that you were listening to in you know a high quality wave or an mp3 basically anything your computer can hear anything you can hear via your computer you can record because you can choose what the input device is um over here and you can choose an application right any application so i could choose to record whatever's coming off of google chrome i'm not going to do it right now because that would create a feedback loop because i'm going through google chrome right now right but if i wanted to i could choose google chrome and it would just uh use google chrome would come into here and then i could route that however i wanted to right i could actually could actually route it yeah this is a little finicky sometimes boom right there i could oh i don't want to do that ah i don't want to do that right now because it'll screw up everything i'm doing at the moment but if i stuck uh ah unattached if i stuck google chrome right uh right here let's see where would i do it i would stick it aha this is where i would stick it hang on let me make everything a little bit closer together for a second i'm just i'm starting you know i'm trying to show you everything at once here so if i took google chrome i could stick it right here and have it attach from uh from here to the recorder and then so on and so forth i'm just like i said i'm not actually doing any of this i'm not going to trigger any of this stuff right now because it'll screw up the actual live stream that i'm doing but the point is you can record from anywhere output to anywhere and process your audio along the way which is really really very uh very cool hank says no hank was not hearing the the the pop so i'm gonna have to explore more about that um a little bit uh a little bit later thank you for letting me know that though hank so i didn't really intend to show off loopback that's kind of its own thing but the point is um with uh with this with audio hijack you can do live streaming and process your audio in real time and avoid all of the issues of live stream audio that you typically get which is your voice sounds thin it doesn't sound even volume do you clip sometimes because you get loud and whatever no you can put on an eq and adjust the tone of your voice you can put on a denoiser at the very beginning of your chain and avoid the fan noise and background you know kind of background hum or or some of that you can put a compressor on to even out the level of your voice during the live stream you can throw a limiter on the end to make sure that if you scream or laugh really hard out of nowhere it's not going to blow out anyone's eardrums and you can monitor the whole thing by uh by looking at the uh the final levels and you can simultaneously while you're doing your live stream record the raw pure audio directly on your computer so that you could actually sync it up later if you wanted to to cut clips and teasers and all that kind of fun stuff you can combine any audio from anywhere to anywhere it's fantastic so that is what i wanted to show you here in real time um so actually you know what one more time i'm going to turn off so let's turn this on i'm going to turn off all of the audio plugins so now you are just hearing the raw audio coming from my microphone into the computer and now you are hearing the processed audio that's got a denoiser and a d-click and an eq and a compression and a limiter so that is the beauty of being able to do this in real time if there are no questions i am planning on making a proper series of videos that not live videos that actually demonstrate and uh and teach uh the different functions within this software should you want to learn it for yourselves did you want to should you want to go pick it up so i'm going to actually produce those for the channel goodness i'm actually going to produce those for the channel but in the meantime if you don't have any questions i'm going to sign off and get back to work i was just excited to show this to you and oh yeah i wanted to let you all know let's see i'll throw this up on the screen here if anyone wants to pick up my uh my audio course um i've got a coupon today uh that is for just for anyone who's watching this i'm only gonna leave this coupon available um for uh just for today so here you go you've got audio 101.info that's my comprehensive course in beginner audio uh not live streaming but you know processed audio how to how to do capture audio process it and output it for content creation it's five four hours of content four hours of instruction over 32 videos and i'm adding videos over the next few weeks as well i'll continue building out that that course it's only been available for about seven or eight months a lot of folks have purchased it everybody loves it it's a super super uh thing um the coupon is for ten
