Learn How to Edit in the Spectral Frequency Display View in Adobe Production Studio


Now, we are going to take a look at the very powerful feature of Adobe Audition called the Spectral Frequency Display. Now in a lot of cases to do audio editing, the audio wave form does not give you quite enough visual information to make your edits. So first of all, let us zoom all the way back out and we can do that simply by dragging the edges of the scroll bar, all the way to the left, and then the right one, all the way to the right, zoom all the way out. Now, let us go to View Menu and select Spectral Frequency Display. You can also use the keyboard shortcut Shift+F. What we are looking at now is the same exact audio file, but it is being displayed visually in a completely different way. So, going from left to right, this is time, go ahead and hit the space bar on your keyboard to playback -- [Demonstration] You can see the current time indicator moving across, and then if we look over all the way on the right, you are going to see these numbers here with an Hz symbol which stands for Hertz. So, this is basically your frequency range, starting all the way at the bottom with lower frequencies moving to higher frequencies at the top. Now, if we go all the way over to the left where all these color information is, what we are seeing here is that where there are lighter pixels in a specific point in time, this means that there is more of that given frequency at that specific point in time. Now, let us see some of the things really quickly we can do with this. Go back to the toolbox in the upper left hand corner, and you are going to see two tools that would be very familiar to you if you were an Adobe Photoshop user. So, the one I am hovering above right now is the Lasso tool, just like the Lasso tool in Photoshop that lets you make selections. Just to the left of that, we will see the Mark Key tool. Same exact idea, you can make selections on your audio, just like you would with the photograph in Adobe Photoshop. So, let us just do a quick edit to this file. Click once to select your Mark Key tool. You can also use the keyboard shortcut letter M, come on down to your audio file and just click and drag a Mark Key around the first line right here. What we are going to do is simply take this component of the audio file and delete it. So, once you have the selected, go ahead and hit the Delete key on your keyboard. You can see now, that element of the audio has been removed. Let us go ahead and do that with the second line down here at the bottom. So, start all the way over at the right where it ends, and just again, click and drag to make the selection around that audio, and then once again, hit the Delete key on your keyboard. And there it is. Now, go ahead and click anywhere in open space to get rid of that selection, and now, hit the Home key on your keyboard to go back to the beginning of the clip, and now hit the space bar to play it back again. [Demonstration] Quite a difference right; let us hear it one more time. [Demonstration] So, you can see, we are actually able to significantly modify that audio file by using the tools in Spectral Frequency view. Now, one very important to thing to remember is that any editing you do here in the Edit View is distractive. So that means, if you go to your File menu and select file save, the changes that you just made will be a permanent part of that file. So, if you would like to experiment and not risk loosing your original audio file, make a copy of that file first before opening it up in the Edit View in Audition 2.0.
