Fixing and morphing sound with the Sample Editor

From: Logic Pro 9 Essential Training

Video: Fixing and morphing sound with the Sample Editor

If you're recording your audio at CD quality, or 44.1 kHz sampling rate, that means each audio file is made up of 44,100 samples per second. You can do so much with regions in the Arrange window. If you really want complete control over every infinitesimal sample of your audio, you'll have to explore the Sample Editor. Before we get there, let's talk about audio edits. As we discussed in the fades video, edits over a waveform can produce clicks. Technically, this is occurring because we have not edited on the zero crossing.

Fixing and morphing sound with the Sample Editor

If you're recording your audio at CD quality, or 44.1 kHz sampling rate, that means each audio file is made up of 44,100 samples per second. You can do so much with regions in the Arrange window. If you really want complete control over every infinitesimal sample of your audio, you'll have to explore the Sample Editor. Before we get there, let's talk about audio edits. As we discussed in the fades video, edits over a waveform can produce clicks. Technically, this is occurring because we have not edited on the zero crossing.

A zero crossing is where an audio waveform, which constantly oscillates between positive and negative axes, crosses zero. Let's use a magnifying glass and zoom way into the shaker track to reveal the crossing point of this edit. Escape, hit our Zoom tool and let's zoom way in, even more, even more than that. There we go. Here we can see this edit has not been made where the waveform crosses zero, at the middle point. To ensure that your edits happen on the zero crossing, you can go up to the Audio menu and choose Snap Edits to Zero Crossing.

Any edits from here on now will be sure to happen where the waveform crosses zero. Let's go back to our Pointer tool and we'll zoom back out. Okay, now you can click on the top part of our shaker tracks and trim our edit and we'll be sure that our edit occur on the zero crossing and not somewhere else. Zooming all that way in to see the shakers was a pain. There's an easier way to look at audio in high-resolution. It's called the Sample Editor. Let's select the bridge beat region at the bottom of our Arrange window. We'll zoom in a little bit to see it.

Now let's open up the Sample Editor. Go to Window > Sample Editor. This is our Sample Editor. It offers us a very close-up view of the audio waveforms in that bridge beat region. In this window, you have complete access to digital audio editing. You can audition the selection by turning on the Loop button. When we hit play, or Spacebar, it will play the whole region and loop to the beginning. (Drums playing.) Hit Spacebar to stop.

You can also view and change where Logic thinks the Selection Transients are by clicking on the Transient tool. Those white lines are where Logic hears the transients of this beat. They are pretty accurate too. You can also use this window to redraw the waveform with the Pencil tool to fix digital clicks and small anomalies. To get to the Pencil tool, hit Escape and you can choose the Pencil tool from the toolbox. Let's go back to the Pointer tool. In this window, you can also change the anchor point. That's where Logic snaps the region to the grid in the Arrange window.

To do this, open the local Edit menu and uncheck Lock Arrange Position when moving Anchor. Now I am going to position the window, so we can see both the region in the Arrange window and the Sample Editor. Click down where it says Anchor and move the Anchor to the third transient. As you can see, when I did that the bridge beat region moved over and now it has a white line. The white line indicates the new anchor point and Logic repositioned the region, so the new anchor points syncs to Bar 60, which was the original start point for that region.

Let's uncheck the transients and move the anchor point back. The bridge beat region returns to its normal sync point. Now let's go back to the Sample window and select the first bar by clicking and dragging in the main area. Since we still have the Loop button selected when we hit Play, we'll hear just as first bar loop. (Drums playing.) We can reflect this selection in the Arrange window by choosing Edit > Selection- > Region.

See how the region in the Arrange window was updated to reflect the selection? You can always trim it back out. Hit Command+Tilde to go back to the Sample window. Finally, there are large amount of processing tools available in the Sample Editor's Factory menu. Before applying any of them, it might be a good idea to go to Audio File > Create Backup. That way you won't write over any file. A lot of these audio processing tools will overwrite the file if you don't do this. So let's create a backup. It asks you, you want to create it, you will say yes.

Now let's go into the Factory menu. We are going to check out one of these tools called Audio Energizer. This tool applies an algorithm to the audio to make it effectively louder in the mix. We can adjust the Factor from quieter to louder. It's more than just turning up the volume. It's actually applying a special process. Let's put this about at 300 and hit Energize. As you can see, the audio waveforms got a lot bigger. Let's hear what they sound like in the Arrange window. (Music playing.) They gave this region a much-needed energizing.

This is just a few of the many features in the Sample Editor. Be sure to check out all the menu items and their powerful features when you have the chance.
