While After Effects is primarily known for motion graphics and visual effects, it also offers basic audio editing capabilities. Trimming audio—whether for syncing music to animation or removing silent sections—is a common task. Here’s a clear and straightforward way to do it.
Step 1: Import Your Audio and Add It to the Timeline
Start by bringing your audio into the project:
1.Go to File > Import > File and choose your audio file.
2.Drag the audio from the Project Panel into your composition timeline.
The audio will appear as a layer alongside your visuals, ready to be edited.
Step 2: Trim Using Handles, Work Area, or Shortcuts
You have a few options to trim your audio clip:
Method A: Drag the Layer Handles
●Click and drag either the start or end point of the audio layer inward to shorten it.
Method B: Use the Work Area
●Adjust the light-gray Work Area bar above the timeline to define the desired section.
●Go to Composition > Trim Comp to Work Area to remove everything outside that range.
Method C: Keyboard Shortcuts
●Split Layer: Press Ctrl + Shift + D (Win) or Cmd + Shift + D (Mac) to cut the layer at the playhead.
●Trim to Playhead: Press Alt + ] (Win) or Option + ] (Mac) to trim everything after the playhead.
Shortcuts help you make fast, precise cuts without using the mouse.
Step 3: Preview and Fine-Tune the Audio
Always preview your edits:
●Press 0 on the numeric keypad for a RAM Preview (includes audio and video).
●Press the period (.) key to preview audio only.
●Slide the entire audio layer left or right to adjust sync.
●Use the asterisk * key during playback to place markers for timing reference.
Frequently Asked Questions
How can I change the length of an audio clip in After Effects?
You can drag the endpoints of the layer on the timeline or use the Work Area method. Go to Composition > Trim Comp to Work Area to permanently crop the composition to your selected range.
Is there a Trim Tool in After Effects?
No, there isn’t a dedicated tool like in Premiere Pro. Instead, you trim by dragging layer handles or using the Work Area. For more precision, use keyboard shortcuts.
Can I edit audio in After Effects?
Yes, but only at a basic level. You can trim clips, adjust audio levels, and create simple fades using keyframes. For advanced edits—such as EQ, compression, or noise removal—it’s best to use Adobe Audition.
How do I trim an imported audio recording?
Drag your audio into the timeline, select the layer, and shorten it by dragging the ends. This only affects the clip inside your project—your original file remains unchanged.
