Lesson 4. Editing Audio Regions > Using the Sample Editor

Using the Sample Editor

The Sample Editor wears its name for a reason: Using this editing window you can zoom in until individual samples are visible. Because the Sample Editor gives you such exact control over audio edits, it's classified as a sample-accurate editor. This contrasts to the Audio window, which allows edits accurate only to within 256 samples.


The Arrange window is also a sample-accurate editing window.

Navigating the Sample Editor

When editing in the Sample Editor, you will often be zoomed closely in on the waveform. Consequently, navigating the Sample Editor becomes a major concern. You could use the scroll bar at the bottom of the window to zip around the file, but when you're zoomed in close, this becomes a difficult and timeconsuming process. Fortunately, Logic provides great techniques for navigating in this window.

In the Audio window, double-click the Kick Region.

The Sample Editor opens.


You can double-click a Region in either the Audio window or the Arrange window to open the Region in the Sample Editor.

As you can see, the Sample Editor already gives you a much closer view of the Region's waveform than either of the other windows.

Drag the Sample Editor's horizontal zoom control all the way to the right.

You are now looking at the Kick Region's individual samples.


You can edit individual samples in a waveform with the Sample Editor's Pencil tool. This comes in very handy when you need to edit pops and clicks out of an audio file—just grab the Pencil tool and draw them out. But be careful: Making this type of edit permanently changes the audio file on your hard drive!

Along the top of the Sample Editor is a waveform overview that shows the Region's entire audio file. At the front of this overview, a dotted box shows you the area of the waveform that's currently in the Sample Editor's main display area. To quickly jump to other points along the audio file, click the waveform overview.

In the waveform overview at the top of the Sample Editor, click somewhere close to the middle (this is just for practice, so it doesn't matter exactly where you click).

The dotted box moves to the clicked area of the waveform, and the Sample Editor's display area updates to show the portion of the waveform outlined by the dotted box.

In the Sample Editor's main display area, Regions are defined by the start and end playback indicators. The start playback indicator looks like a rightpointing arrow with an S on it, while the end playback indicator is a leftpointing arrow labeled with an E. Somewhere between those icons you'll find the Region's Anchor, which looks like an upwardpointing triangle. (You'll explore Anchor points a bit later in this lesson.) When you're zoomed in close on a waveform, these three things are a bit hard to find. You can click the waveform overview to get close, but the following key commands are much more precise:

Press the right arrow key on your computer keyboard.

The Sample Editor jumps to display the Region's end boundary indicator.

Press the down arrow key.

The Sample Editor jumps to display the Region's Anchor.

Press the left arrow key.

The Sample Editor jumps to the Region's start boundary indicator.

Remember these three key commands: Using the arrow keys provides a convenient way for you to quickly jump between Region boundary indicators and the Anchor without having to zoom out and find the part you're looking for.

Close the Sample Editor.
