Audition CS6 Essential Training demonstrates all of the major features of Adobe Audition and prepares sound editors to start enhancing and correcting audio—whether it's music, dialogue, or other sound effects. Author and musician Garrick Chow begins by covering how to import, record, and manage media files, from extracting audio and importing video, to creating a new multitrack session from scratch. The course then dives deep into editing, repairing, and cleaning up audio files, using the Waveform and Multitrack Editors, and the Spectral Frequency Display. It also covers how to use built-in effects, how to mix both stereo and surround audio tracks, and how to work with video projects from Premiere Pro.
You've probably noticed this tool that's sort of hanging out near the top of the Waveform Editor. This is the Amplitude Adjustment tool, and it allows you to increase or decrease the loudness of a selection you have made. Now, in some cases, you may want to increase or decrease the volume of the entire clip, in which case, simply click anywhere over the graph or dial or text here and drag left or right. And while you're dragging, you get a real-time representation of how much you're increasing or decreasing the amplitude as the waveform grows and shrinks. So maybe I want to increase the amplitude to about 4 dB. So there's 4.2 dB right there.
I release and Audition takes a moment to make my change, and there it is. Now, you might have noticed that when I released my mouse, the Amplitude setting went back to 0 dB. It does this in case I want to make further adjustments, and that way I can know how much I'm increasing or decreasing the amplitude from the current level. As with all yellow underlined text, I can click on that number, and I can type in a value. So if I wanted to take this back down to its original level, I could type -4.2 dB, press Return, and there it is. Now, as I mentioned, the Amplitude tool works for whatever you have selected.
If you don't have anything selected, it adjusts the entire clip, but if you only want to increase or decrease the volume of a certain section, first make your selection and then change the amplitude. And as you can see, only the contents within that selection are then changing. I'm just going to undo that. Also notice how the tool stays centered within my selection as I'm making it. It's just dropping to wherever I'm making my selection. That can be useful if you're making a bunch of selections and you don't want to have to keep moving your mouse back to the center of the screen.
Now, there's a Pin icon right here. Just drag it over here, for example. If I click that pin, I'm pinning this Amplitude Adjustment tool to its current location, which is what you can do when you don't want it to move. So now, as I make my selections, it stays in one place. And you're also free to drag this tool around anywhere else within the editor that's convenient to you. And as long as the pin is selected there, it'll stay pinned to whatever location you drag it to. If you unpin it, it'll start jumping to your selection again. Now, when it comes to adjusting amplitude, you should always keep an eye on the level meter down here.
As a general rule, don't increase your volume to the point where these two indicators at the end here turn red. Just to give you an example... (male speaker: --for a character. After that, we'll take a look at inverse kinematics and the various inverse kinematics tools as well--) This indicates that your level has clipped, and you probably heard a little bit of distortion that appeared when I drag the levels too high. The reason these stay red is because you might not always notice of a portion of your recording has clipped. It might just be a split second. So when you do glance down here, you'll know that something was too loud at some point. You can go back through and try to find the problem.
You can turn these red lights off again just by clicking them, and I'm just going to undo my last change here. All right, so that's the Amplitude Adjustment tool for increasing or decreasing the volume of selections you make in your waveform.
