Questions, answered
Silence remover FAQ
How is silence detected?＋
The tool measures short audio blocks. Blocks below your dB threshold for at least the minimum duration are marked as silence.
Why keep padding?＋
Padding preserves a small amount of room tone around speech and helps avoid cutting the beginnings or endings of words.
Does this upload my recording?＋
No. Decoding, analysis, joining and WAV export all happen in your browser.
