Frequently asked questions
How does the tool detect what counts as silence?
The engine evaluates acoustic decibel (dB) levels across 50ms windows. Segments that fall below your custom threshold (e.g. -40dB) for longer than the minimum silence duration are automatically trimmed.
Can I leave a short natural pause between sentences?
Yes. You can set a buffer padding (e.g. 100ms) so speech transitions sound natural and conversational rather than clipped.
How much time does silence removal typically save on podcasts?
On unedited interview recordings and voice memos, stripping dead air typically cuts total listening time by 15% to 30%.
