Frequently asked questions
How does the tool know what silence is?
It treats as silence any stretch below the chosen volume that lasts longer than the minimum time. For recordings with background noise, use the −30 dB threshold to cut more.
Do the pauses disappear completely?
No. The tool leaves a short breath in place of each long pause, so the speech does not run together.
