Select audio in the Audio File Editor in Logic Pro for Mac

To start editing and processing audio in the Audio File Editor, select an area within the waveform display. Any editing or processing you perform affects only the selected area.

The start point and length of the currently selected area are shown in the info display—above the waveform overview. The format of the information is based on the setting chosen in the View menu. See Change the Audio File Editor ruler display.

Use the basic selection techniques outlined below to select an entire audio file, or part of an audio file, for editing or processing.

For tips about accelerating the selection process, see Navigate audio files in the Audio File Editor.

Select the entire audio file

  • In Logic Pro, choose Edit > Select All (or press Command-A).

Select a section of an audio file

  • In Logic Pro, click and hold the start or end of the area you want to select in the waveform display, then drag to the right or left.

    The start point and length are displayed (as sample words) in a help tag while you make your selection.

Extend an existing selection area

In Logic Pro, do one of the following:

  • Choose Edit > Select All Previous (or use the corresponding key command).

  • Choose Edit > Select All Following (or use the corresponding key command).

Define the selected area using a region

  • In Logic Pro, select a region in the Browser or main window, then choose Edit > Region → Selection.

This function is useful if you want to reselect the entire region for cycled playback—after performing a number of edits, for example.

The reverse can also be done, allowing you to redefine the length of an existing region by choosing Edit > Selection → Region.

You can modify selections by changing their start or end point, or you can move the entire selected area completely.

Note: If you choose Edit > Snap Edits to Zero Crossings, any length adjustments to audio region start or end points snap to the nearest zero-crossing point of the waveform.

Change the start or end point of an existing selection

In Logic Pro, do one of the following:

  • Shift-click in the waveform display to move the start or end point.

  • Press and hold Shift as you drag the start or end point of the selected area in the waveform display.

Using either method, the proximity of your click—to the start or end of the selected area—determines whether you change the start or end point boundary. The closest one wins.

Tip: If you press and hold Option-Shift, the more distant selection boundary is changed (rather than the nearer).

Move the selected area

You can move the whole selection to the left or right without changing its length.

  1. In Logic Pro, do one of the following:

    • Option-click the selection.

    • Click the selection with the Move tool.

  2. Drag left or right.

When you move the selected area, the pointer or Move tool turns into a two-headed arrow.
