How does the silence remover work?

The silence remover analyzes the audio waveform of your video using FFmpeg in the browser. It detects silent segments below a configurable decibel threshold and automatically trims them, producing a seamless video without dead air.

Can I customize the silence detection threshold?

Yes. Use the Decibel (dB) slider in the Silence Remover panel to set the sensitivity (e.g., -60 dB to -10 dB) and the Minimum Silence Duration to fine‑tune detection.

How do I mute a video?

Open the Mute/Soundtrack tool, toggle the mute switch, and click Apply. The video is re‑encoded without its audio track using FFmpeg WASM.
