How does silence detection work?

AI analyzes audio energy levels to identify segments below your chosen threshold, then removes or speeds up those sections.

Can I adjust the sensitivity?

Yes, you can set the threshold from aggressive (remove everything) to conservative (only obvious silences).

Will it cut in the middle of sentences?

No, the algorithm includes a safety margin around each cut point and uses crossfades for smooth transitions.

Can I speed up silences instead of cutting them?

Yes! Choose 'speedup' mode to fast-forward silent sections at 4-8x speed instead of removing them entirely.

Does it work with music in the background?

Background music may interfere with silence detection. For best results, use videos with primarily spoken content.

What's the maximum video length?

Up to 2 hours with a free account, unlimited with Pro.

Can I speed up silences instead of removing them?

Yes. Choose the "speedup" mode to fast-forward silent sections at 4-8x speed rather than cutting them entirely. This preserves the visual continuity of the video.

Should I remove silences before or after adding subtitles?

Always remove silences first. Subtitle timing is based on the final audio, so cutting silences after adding subtitles would break the synchronization. Use our subtitle tool on the tightened version.

Can I combine silence removal with filler word removal?

Absolutely. For the cleanest result, remove filler words first (they are speech, not silence), then run the result through the silence remover to cut remaining pauses.
