Silence Remover

Cuts long silence blocks out of speech recordings automatically. For unedited podcasts, lecture audio, interviews and dictations.

What it does

Use this to drop long pauses between sentences, "umm" pre-silences, and gaps between questions and answers. Cuts the duration by 30-50% so the listener does not lose interest.

Note: Audio only. For silence in videos use the Video Jump-Cut tool.

How to use

  1. Drag audio files into the list.
  2. Set the Sensitivity (Threshold) (default -40 dB).
  3. Set the Minimum Silence Duration (default 400 ms).
  4. Set the Padding keep-amount (default 100 ms).
  5. Click Run.

You get one trimmed copy per file.

Settings

  • Sensitivity (Threshold): What level counts as silence. -60 dB is very sensitive (cuts micro-silences too), -20 dB only true silence. -40 dB is balanced.
  • Min Silence Duration: Silences longer than this get cut. 400 ms keeps natural speech pauses. 1000 ms only kills the long ones.
  • Padding: Leaves a sliver of silence at the start and end of each kept segment, so cuts are not jarring. 100 ms is standard and feels natural.

Examples

Make a lecture listenable: Add the recording, threshold -40 dB, min duration 800 ms, padding 200 ms, run. Long pauses go away.

Tighten a podcast: Add the podcast, threshold -45 dB, min duration 500 ms, run. Tempo lifts without losing the natural flow.

Compress an interview: Add the interview, threshold -40 dB, min duration 1000 ms, run. Only long thinking pauses go.

Strip pauses from dictation: Add the dictation, threshold -35 dB, min duration 300 ms, run.

Watch out

  • Very sensitive threshold (-60 dB) with very short min duration (100 ms) breaks natural speech flow, sounds robotic.
  • Do not use on recordings with music, the quiet parts are part of the music.
  • Very low padding (0 ms) sounds choppy.
  • The change is not reversible, keep the original.
  • Every silence is cut, even deliberate dramatic pauses.
