Strip Silence allows you to identify and remove silent or inactive regions in recorded clips, without losing synchronization in multitrack audio. Use this feature for cleaning up voice recording, interviews, and preparing multi-track edits, such as podcasts or audio documentary content. Strip Silence parameters can be adjusted for unique scenarios, such as noisy backgrounds or different volume levels between participants, to easily identify and remove regions in the track that have no content, saving editors time.
Apply Strip Silence to a track and edit the settings
Once the issues are detected, you can fix them using one of the two options:
- Strip Silence - Cut and delete the silence entirely.
- Split Silence - Cut the clip but leave them selected so that you can verify if the right part has been selected.
Tip: Strip Silence is better used in podcast interviews or audios where the silences are well-defined. For more complex audios with lesser silences and voice modulations, you may go for Split Silence.
Edit effect parameters
Based on your audio, the Deleting Silence effect auto detects the best decibel and time settings.
You can still set the threshold manually if your workflow demands.
To open/close the effect parameters, click the Settings button next to Scan. Adjust settings for the following:
- Define Silence As: This feature detects silences based on the threshold. Anything that is below the threshold is categorized as silence. Drag the Signal is below slider to set the decibel manually in dB, and drag the For more than slider to set the time in ms.
- Define Audio As: This feature detects silences based on the threshold. Anything that is below the threshold is categorized as audio. Drag the Signal is below slider to set the decibel manually in dB, and drag the For more than slider to set the time in ms.
