### Step 1 : Launch AutoCut Silences & Define sections
Select the audio section to be analyzed and trimmed by AutoCut Silences. You can choose from:
* Entire timeline
* In/Out points
* Selected clips
Just according to your needs and confirm your choice.

### Step 2 : Adjust noise level
You can manually set the noise level, which is crucial for detecting silences. Any sound below this threshold will be considered silence.
For an optimized workflow, use the '**Calculate by AI**' option to automatically set the appropriate decibel level with AI assistance.

### Step 3: Set up the silence duration
Set the durations of silence and speech to keep or remove.
* **"Remove silences longer than"**: Determine the minimum duration (in seconds) of silence to remove. If the silence is shorter, it will be kept.
→ **Use this setting to avoid removing silences that are too short.**

* **"Keep talks longer than"**: Set the minimum duration (in seconds) of sound to keep. If the sound is shorter, it will be removed.
→ **This setting allows you to exclude very short sounds like a cup being put down or an accidental bump on the microphone.**

### Step 4: Margin
Set the margin around each cut for a more natural edit.

|| 💡 Margin helps avoid cutting the beginning or end of a sentence, making the video edit smoother.


### Step 5: Silence management & Transition
Choose how to manage the detected silences. We recommend using the "Remove Silences" option that fits most edits. Then, select the transition to apply to each cut.
