How to remove echo from audio in audition

And if I can find just that hum, even if it's in the bottom end, I can select some of the bottom end in other places, and Audition will combine all of that in the Sound Model itвЂ™s learning in order to to figure out exactly what I'm trying to get rid of. Now, the beauty of this tool is that not only can I choose the area that I've already chosen, but I can also look at other places in the track where there's silence. To prepare Audition to apply the Sound Remover effect by telling it to analyze your selection, go to Effects > Noise Reduction/Restoration > Learn Sound Model ( Figure 5, below).

So get to where it looks visually accurate to you (keeping in mind that you can adjust it later after previewing the effect), leave it right there, and see what it does. With a low-frequency hum such as this one, you want to be careful about taking out too much for fear of losing some of the low end. Adjusting the paint with the corner guides. You can adjust it (raising, lowering it, or extending it further along the timeline) very easily with the corner guides, top and bottom, shown in Figure 4 (below Figure 3).ДЇigure 4. And if you don't do it quite right with a paintbrush, if you're a little loose with it, don't worry about it. Next, you need to paint over the frequency ( Figure 3, below) that we identified as the hum in Figure 1. To begin, choose the Paintbrush Selection tool (keyboard shortcut F), shown in Figure 2 (below).ДЇigure 2. But Audition CC has a slightly different way of doing that with the new Sound Remover tool, which is designed to clean up variable frequency noise. How are we going to get rid of that? You could choose to select it and set a noise print and then get rid of it, and thatвЂ™s how we would most likely have done it in earlier versions of Audition. And you can see it very easily at the bottom of the frequency spectrum shown in Figure 1. But it is there, as we know from the visual representation in the waveform. So you may have been able to hear that hum and maybe you couldn't. If you listen closely, you can get a sense of what it sounds like at the 1:00 mark in the clip below. But there is a distinct hum if you listen to it on a good set of headphones or speakers. It's not very perceptible, probably, listening to this online. WeвЂ™ll take care of it with Sound Remover. Note the low hum visible in the waveform. You can see that there's a little bit of low hum where the pointer is hovering in the waveform shown in Figure 1 (below).ДЇigure 1. I have a track here that I recorded straight from a vinyl record through a USB turntable. If you've ever used some sort of noise removing tool in any other app, you'll find that it's similar, but distinct in a small way. The first feature I want to show you is called Sound Remover. IвЂ™ll supply timecodes so you can jump right to the spot where I play the clips. Note that to follow along with the text of this tutorial, youвЂ™ll need to refer to the video version embedded in the article if you want to hear the audio issues IвЂ™m describing in the example clip. IвЂ™m going to show you a couple of the new things that you have to look forward to when you decide to upgrade, or when those of you who have upgraded but havenвЂ™t explored its features yet start using it in your projects. I imagine that lot of you have probably updated, while some of you are still on the fence.

In this tutorial I'm going to walk you through a couple of the new features in Adobe Audition Creative Cloud (CC).
