What does Silence & Pause Remover do?
Tubelexity finds quiet sections in spoken videos using audio-level analysis, then lets you shorten or remove each detected pause. It is made for creators tightening tutorials, interviews and talking-head recordings. Analysis uses the Web Audio API and export uses local FFmpeg.wasm processing. You can review every proposed cut before downloading a watermark-free video.

How local processing works
Processing runs locally in your browser with FFmpeg.wasm. The media engine is downloaded on first use, but your media is not sent to Tubelexity or a processing server.
Frequently asked questions
Can I remove silence from a video for free?
Yes. Tubelexity detects quiet sections and lets you shorten or remove them in your browser without charging credits or adding a watermark.
Does the silence remover transcribe my video?
No. It measures audio amplitude with the Web Audio API and does not use speech recognition or AI.
Does my video leave my device?
No. Analysis and export run locally in the browser; the FFmpeg core is downloaded separately on first use.
Will removing every pause sound natural?
Not always. The Natural preset preserves short conversational pauses and is the safer starting point for speech.
Why can large videos take longer?
Browser processing is limited by your device memory and CPU, and precise export must decode and encode media locally.
