Frequently Asked Questions
Which silence sensitivity should I choose?
Balanced works for most files. Use Low for clean recordings with obvious silent gaps, or High when quiet pauses need detection in a low-volume recording.
Will it remove pauses between spoken words?
It targets quiet sections that remain below the selected threshold for long enough. Natural short pauses are less likely to be removed than longer silent gaps.
Can background noise affect silence detection?
Yes. Constant fans, traffic, or room noise can prevent a section from being classified as silent. A higher sensitivity may help, but test the output carefully.
Can I remove silence from video audio?
Yes. Upload a supported video and the tool will process its soundtrack. The downloadable result is a shortened MP3 audio file.
