Removing room echo with Audition, Premiere Pro + Unveil

hello and welcome to video revealed I'm Colin Smith and this is your place for professional video production techniques the subject of this reveal removing room echo in Adobe Audition and Adobe Premiere Pro all right I've got a clip that I recorded with a ton of room noise let's have a listen alright I'm recording this with the built-in microphone on my Canon 5d Mark 3 this is a way that many folks will record audio and they want to fix it and the problem is caused by the camera being about 60 at 10 feet away and we're in a reflective surface so this is my kitchen we've got tile floor wood cabinets and a hard countertop which is making all of the audio echo all over the place and it actually smears together that's what you hear when you hear room tone and that's why it's so difficult to be able to fix that because it's not a simple reflection it's actually a bunch of sound waves smearing together by the time they come from my my mouth hit all these surfaces and then get them picked up by the microphone so we're going to try to take this out using software and remove the rest of the room tone all right so as soon as you hear that I think everybody recognizes that poor quality reflection in the room and I'm going to show you two different ways to do it one is using Adobe Audition and another is using a plugin in audition or in Premiere Pro called unveil let's go have a look so the first thing we need to do is to get this clip in to audition so the best way to do that is we can right click on the clip edit an audition clip audition actually extracts the audio if we go back to Premiere Pro you can see Premiere Pro extracted that and sent that over here to audition it's the same audio rolling alright I'm recording this with a built-in microphone on my Canon 5 so the first thing to do would be to remove the noise and we can't really see the noise in the waveform view but up at the top if we go to our spectral frequency display you can see a lot of noise so if we go to this section here that's noise and if you select it with the i-beam that's this tool up here that's the default tool select all of that right click and choose capture noise print this now tells Adobe Audition what is noise and if you don't have an area where you're not talking then you can't do this that's why it's always smart to leave that the recorder running a little bit longer if you're doing it on an external device or the camera itself and you only need a small part now that we told Adobe Audition what is noise let's go remove that so in the effects controls noise noise reduction process and we'll select the entire file right here click that and now let's listen to it rolling alright I'm recording this with the built-in microphone on my Canon Drive on mark 3 this is a way that many folks will record audio and they want to fix it so it's removed some of that noise but if you twirl down the Advanced section here you'll see something called the spectral decay rate and if we reduce this amount from 65 which is the default amount take it all the way down to zero we're going to reduce the amount of the effect letting things go by so it's not really a noise gate it's it's the noise reduction process but it's just clamping that a little quicker rolling all right I'm recording this with the gelatin microphone on my Canon 5d Mark 3 this is a way that many folks will record audio and they want to fix it and the problem is caused by the camera that's doing a pretty good job so let's apply this this is not an effect that can just sit there we have to destructively apply it so I'll click the apply button and now you can see that the some of that reflection is gone I'm recording this with the built-in microphone on my Canon but there's a few of the things that we can do in audition and that's try to find the frequencies that are the most annoying frequencies and I'll just go back to my waveform view right now go to my effects and we'll choose the pair metric equalizer and by default we get a whole bunch of bands to play with I'm going to shut most of these off and just work with those three so you can turn all of them on or off however you want so the way that this works is in the center you're not influencing you're not adding or reducing a frequency and each one of these points can be pushed up and push down and you can use these buttons down here these to move this up and down so a simple way to identify a problem frequency is to increase the frequency and then change the Q value so if we turn this to a higher level we get more of a peak this helps us isolate a specific frequency when the Q value is wide it's going to be pulling a lot of frequencies we want to try and isolate something that's a problem so what we'll do is we'll turn that up and then we'll sweep this back and forth while we listen to it okay I'm recording this with the built-in microphone on my Canon 5d Mark 3 this is a way that many folks close off road audio and they want to fix it and the problem is caused by the camera being about 60 at 10 feet away and we're in a reflective so I happen to know that this one is around 40 129 I'm recording this with a built-in microphone on my Canon so that helps us identify the frequency obviously it made it worse so let's reduce that amount so instead of pushing it up we'll take it down I'm recording this with the built-in microphone on my Canon 5d Mark 3 this is a way that many folks will record audio and they want to fix it and so fun weather frequencies in here that are also a problem let's try to isolate those same thing turn it up narrow q-value and sweep I'm recording this with a built-in microphone on my canon 5d mark 3 this is a way that many folks will record audio and they want to fix it and the problem is caused by the camera being about 60 at 10 feet away and we're going to reflect this residue so this is my kitchen we've got tile floor wood cabinets and a hard countertop all right so so far we found two really horrible frequencies that were caused by the reflection in the room and the tone of my voice in this recording there's one more a little bit lower let's look for that so again let's turn this up and let's keep this narrow and sweep I'm recording this with a built-in microphone on my Canon 5d Mark 3 this is a way that many folks slow record audio and they want to fix this reduce as a problem is caused by the camera being about sixty to ten feet strain this off and we're in a reflective surface so this is my kitchen we've got tile floor wood cabinets and a hard countertop which is making all of the audio echo all over the place and it actually smears together that's what you hear when you hear room tone in that all right and then we'll click to apply this and now we've all right I'm ready Joan this with the built-in microphone on my Canon 5d Mark 3 this is when you click Save if we go back to Premiere Pro it's going to save that file so right this is our audio and the problem is caused by the camera being about 60 at 10 feet away and we're in a reflective surface this is the original so we're going to try to take this out using software Andrew so audition does a pretty good job now there's one other tool that I want to show it to you it's not part of Creative Cloud but it blew me away I've been in this industry forever unveiled by synaptic freaks me out we can use this it's a plugin that you have to buy but it runs both in audition or in Premiere Pro as a second third party effect so in Premiere Pro in the Edit preferences Audio and this is in the the Premiere Pro menu on the Mac at the bottom is the audio plug-in manager when you click on that you can see I've just found where this is installed in my VST plugins' once you install that plug-in and show it to Premiere Pro now when we go to our audio track mixer and if that's not already showing go to the window menu audio track mixer and twirl this down twirl this down and look for the VST effects there's the unveil VST double click on it and it helps reduce room noise like I've never seen before it's just absolutely miraculous let's have a listen to this alright I'm recording this with the built-in microphone on my Canon 5d Mark 3 this is a way that many folks will record audio and they want to fix it and the problem is caused by the camera being about 60 at 10 feet away and we're in a reflective surface so this is my kitchen we've got tile floor like magnets and a hard countertop which is making all of the audio echo all over the place and it actually smears together that's what you hear when you hear room tone and that's why it's so difficult to be okay now I hope you see why I included it in this demonstration like I said if you only have Creative Cloud in Adobe Audition you use those two methods you're going to do great and by the way shout out to Darren Durand leaves at Adobe who helped me out with this he's a on the audition team and he's a brilliant engineer but he also mentioned unveil and I've used different ones in the past but when I tried this out I mean you heard it the results are un-freakin'-believable it's an extra third-party tool but well worth it if this is the only audio you have alright I want to thank everyone for the wonderful support here at video revealed I really do appreciate it if you're new to
