Surround Sound in Adobe Audition Tutorial

all right class we are going to create a soundscape using adobe audition for surround sound audio i've loaded all of my wav files i've made sure that they're all the same sample rate they're all at 44 kilohertz and 16 bit but i don't care if they're stereo mono that doesn't matter i actually don't care if they're all loaded or not but it's more helpful to make sure they're all loaded what we're going to do however is multi-track mixing file new and instead of saying audio file we're going to say multi-track session and when i do that i'm going to call this last name bendis surround demo and i want it to be 44 kilohertz 16 bit and instead of mono or stereo we're going to do 5.1 because this is a surround sound demo so these are the standards that we're going to be using and i click on ok and when i do that it's going to get really fun in here because now i've got multi-tracks and i've got multiple tracks here and i've got track 1 track 2 track 3 track 4 track 5. now anything that i would want to do individually to the clips i would want to do that ahead of time so if i wanted to make some not louder and softer but if i wanted to do something where i was going to do an echo or a reverb or a fade in or fade out i could do that to my individual files i'm not going to worry about that right here what i am going to do though is i'm going to grab the long uh marimba loop which is i think eight seconds long oh my god how long is that and i'm going to drag it in over here and there it is and if i press play now unlike before when i was editing the file i was editing the file now i'm actually going to be editing the project file the layers are in the project and things that i if i were to come over here where it says uh the gain was this volume and i were to lower it by dragging it this way and try it again that is not the original file what that's telling me is that anything on this track i'm going to lower the volume for i'm going to come over here and i'm going to copy and i'm going to paste it a few times and it will snap into place so this way i just have a few seconds to work with it's not a good loop i know this because i didn't bother to make it a good loop but let's take a listen great now i've got a nice stereo system up here i could be doing this with headphones it doesn't matter what i do want to do is come over here to this little thing over there do you see that little box over there if i double click on it what it's going to show me is it's going to show me the 5.1 it's going to show me the five so there are the speakers left surround rights around left right and center and by default it's right over here this is going to be where the sound is the sound is towards the center and it's going to show me basically how this is affected towards the speakers if i were to press play again you'll notice that down below you see the the only the stereo moving because it's all meant to be left and right and again these are the this is the volume for all six channels let me come back over here and show you what happens if i move it around i'm going to move it towards the back and if i move it towards the back you see over here it's towards the back matter of fact if i move it around any way i want you can see where it's putting it spatially you can't hear it though or can't you hear it you can't hear it because you don't have a 501 surround sound system hooked up at home you're like wait a second you've got a 5.1 surround sound system hooked up here but it's not been configured yet let me show you what happens if i do this i go to edit preferences audio hardware you're going to notice that if i click on audio channel mapping that it doesn't actually show me anything except my stereo channel 1 and channel 2 which is stereo which is what's going to look like when you get home for me to make this work if i did have surround sound to was api it will like this i will change it to sound blaster and now if i go to audio channel mapping you'll notice that i have six channels one two three four five six and i've mapped those channels to left right center lfe is the subwoofer for the low frequencies and outlet left surround and writes around and you can see they're mapped accordingly and hopefully they're there are the right ways actually i don't think that's actually right i do believe that the third channel is left surround i do believe that five is center and six is subwoofer and four is left surround and 5 is right surround and that's very important if i were to really care about this i think i did this wrong i mean i'm sorry that was three and four three and four and this allows me to identify things as i go forward now let's try it again so we'll see how this plays out so that's the left surround that's the right surround that's the right that's the left and that's the center and as i move it around you can see if it's directly in the center all the speakers play if i move it towards the front only the front speakers play move towards the rear on the rear speakers play if i actually put it in the hole only that speaker plays and that's really rare that you would do that but this allows us to come around here and to choose how on edge our audio is and how full our audio is does this make sense so i'm basically and when i do this it's very interesting to realize that when i'm doing this is it's for the whole channel so if i leave it there it stays there so if i come over here and put this on this channel and i put this over here on this channel i can then say i want the elephant to come from the left and now the elephant is located on the left side and if i were to bring up the cat's meow if i would bring up the cat's meow and put it here i can say the cat's meow comes from the right but more towards the front and if i come down here i could say that i want the piano falling down the stairs to be way in the back and if i were to if i were to come back over here and rewind and play this now each of these tracks is placing the audio where i want it spatially will i be able to hear it fully mixed no no it won't because i don't have a 501 surround sound but i'll be able to visualize it in my head and i'll even be able to see how the audio is mixed down below where the levels are let's try it again [Music] [Music] and you're like wait a second how come the middle one didn't ever move that's the low frequency we haven't given it any low frequency and that's actually not uncommon low frequency actually isn't always encoded inside of the audio clip sometimes low frequency is just extracted afterwards by the subwoofer system i'm actually not worried about whether or not you put in low frequencies or not a lot of times it'll come on its own oh wait a second there it is there's a low frequency i can add some low frequency and right there i can say how much of this channel is low frequency there we go let me come back over here to track one and let's increase the amount of low frequency we have there you go there you go there's adds the low frequency in so we've said which channel is contributing [Music] and so the our piano is going to have a lot of subwoofer in its and there there you go now this is a project file this file um when i go to hit save is being saved as a ses x file it's an audition session file it is dependent on the original waveform files so you can come back here and you can edit it but like working in premiere pro you don't want to lose the bits and pieces that you were working with or won't know what to do so far this should be fairly straightforward you have multiple tracks you put items on those tracks and each of those tracks you can change the volume for if i come over here you can change the volume for the track obviously you can always go down never go up because you can spike it you can change the location of where that track is located and there you go does that make sense the last part is the weird part it's the most advanced part that everyone's going to want to do this but at some point you are going to want to think it through so let's say for a moment that i've got this piano that's about to fall and right now where's my piano right now my piano is in the back what if i want my piano to animate what if i want the location of the piano to move over time so what i can do is i can i can come over here and i can stretch you notice that when i'm using the when using the middle the the scroll wheel on my mouse i just see track one two three and four but then when i scroll up i see more first i see the volume control and the spatial control and now i see the default stereo input and now i see the word read and this is where it gets fun because instead of read scroll down so you can see it instead of read i'm going to put this onto right and what this means is that when i press play that this track is going to be a live control of whatever i change and it's going to create keyframe animations for the spatial sound watch i'm prepped to go i'm ready to go i'm ready to play i'm gonna i'm gonna use my spacebar on my keyboard to get it going and then i'm gonna come over here and move it all the way around [Music] and if i hit stop now it's on touch and if i go back to read you can see well you can't see anything you can't see what this is at all and the reason is is that when we look at this what are we looking at well what we're looking at is just our standard output and what does this line mean that line means volume well if i were to come over here i should be able to visualize not the volume right click one moment i always make sure i do it right so right now i'm looking at the volume what i want to do is i want to change the volume to one of the other things that i would look at all right so next to read if i click on this little triangle you're going to see where it says show envelopes now the envelope is this line up here and the line is volume which of course is not what we animated what did we animate we animated the pan and if i were to look at the pan center oh that didn't do anything if i were to look at the pan radius oh look at that that's the animation for the pan radius that's the animation for the pan angle not for the pan center and not for the pan or lfe because that's down here we didn't change it dynamically but we did change the angle on the stereo spread and that's the two things that we changed so that is the animation now why am i showing this to you two reasons the animation is assigned to the track not the contents of the track if i were to move this over here those animations stay over there does that make sense so you need to realize that if you wanted to reanimate that you would have to go through and reanimate it which i can easily do by the way i could come over here and i could say i can change it from read to right and [Music] [Music] and there you go make sure you set it back to read afterwards and you can see that it changed so this is going to allow you to do things like create footsteps that walk across the room create a bee that buzzes around your head close and far and again you can go back and you can animate different things you could animate the volume you could animate the different stuff that you needed to to create the effects that you want our exercise is very simple without the benefit of a surround sound system with just this in front of us can we craft a one minute soundscape no words no talking no language one minute using only sounds that are in the public domain creative commons zero or sounds that you created yourself they are going to be layered those layers can change volume those layers can be you can you can literally work with tracks where everything is just placed and create a very good soundscape because you can have many many tracks in many many places or you can animate those tracks as well so what do you do when you're done please remember that also when you're doing this that not only are you going to be moving where are you in space which which you notice is changing the radius and the angle so the angle is the angle is over here which and the radius is over here those are the two things that really changing and then again you get to choose what you want the subwoofer to do the lfe what do you want the subwoofer to get its noise from in this case maybe i don't want the meow to be coming from the base maybe i want the meowth coming from the piano and while we can set it up that it will just grab whatever the low frequencies are and make them the subwoofer the best control is to be in control of everything when i'm done i can save my project and you probably you should keep saving your project along the way but when you're very done when you're ready to turn it in you're going to do an export as a multi-track mix down of the entire session at this point it's going to give you a brand new option and we're going to use the aiff file format that's the one we're going to use i like the aiff file format and if i click on ok it's going to mix it down to a 5.1 file now while i still have all of these multi-layers over here each track laid out to do whatever i want if i were to open up that file oh look it's already opened up this is what that looks like left right center lf low frequency left surround writes around those are the six tracks and it is agnostic to the system it will play that when i hook this up properly again this is all in your mind's eye and when we're done we're going to set up the 5.1 surround system we're going to put four or five carriers in the middle of it we're going to play everybody's minute once i'm going to play everybody's minute a second time and that's the assignment and it really is about trying to visualize spatialize the audio what do you want where and how can you set that balance
