Edit audio files with transient markers in Logic Pro for Mac

In Logic Pro, do one of the following:

• Choose View > Transient Editing Mode from the Audio File Editor menu bar (or use the Toggle Transient Editing Mode key command).

• Click the Transient Editing Mode button in the Audio File Editor.

  

When you turn on Transient Editing mode, the audio file is analyzed for transient events, and all detected transients are marked in the audio file.

The level of transient detection confidence is based on the clarity of the transients. If an audio file does not have clear, sharp transients, transients are detected with a lower level of confidence. You can display more or fewer transients by using the Plus and Minus (+/−) buttons.

• Plus button (+): Increases the number of transients in the selected area of the audio file, or across the entire audio file. You can also use the Increase Number of Transients key command, default assignment: Command-Plus (+).

• Minus button (−): Decreases the number of transients in the selected area of the audio file, or across the entire audio file. You can also use the Decrease Number of Transients key command, default assignment: Command-Minus (−).

• In Logic Pro, click the waveform display with the Pencil tool.

  

A transient detection process is started for the audio material around the clicked position, and the transient with the highest energy becomes valid and is marked. If no transient is found in the catch area, a transient marker is created at the clicked position.

• In Logic Pro, drag an existing transient marker to another position.

  

  Note: The new position may or may not snap to zero crossings, depending on whether or not Snap Edits to Zero Crossings is chosen in the Edit menu. You can also Control-click to open a shortcut menu and choose Snap Edits to Zero Crossings.

In Logic Pro, do one of the following:

• Double-click individual markers with the Pointer or Pencil tool.

• Click individual markers with the Eraser tool.

• Drag over multiple markers with the Eraser tool.

• Select an area of the audio file and press the Delete key.

All transient markers in the selected area are deleted.

• In the Audio File Editor, choose Audio File > Detect Transients (or use the Detect Transients of Audio File key command).

Transients are detected across the audio file, overwriting (after you confirm the action) any manually added or edited transients.
