FAQ
How does silence detection work?
The tool uses Web Audio API to analyze your file's audio waveform. It scans for segments where the amplitude falls below your chosen threshold for longer than the minimum duration you set.
Can I adjust how sensitive the silence detection is?
Yes. The threshold slider controls what volume level counts as silence (in dB). Lower values detect only very quiet segments, while higher values catch softer speech too. You can also set minimum duration and padding.
Is this a free alternative to Recut or TimeBolt?
Yes. CutFast Silence Remover provides similar silence detection and removal functionality for free, directly in your browser — no downloads or subscriptions required.
Are my files uploaded to a server?
No. All processing happens locally in your browser using Web Audio API. Your files never leave your device.
Can I use this for podcast editing?
Absolutely. Silence removal is perfect for cleaning up podcast recordings, removing dead air between speakers, and tightening up the pacing of your episodes.
