Silence Trimmer

About the Silence Trimmer

The Silence Trimmer detects and removes silence from an audio file — leading and trailing dead air, plus the long gaps that creep into interviews and voice-over takes. You control how quiet counts as silence (the threshold in dB) and how long a gap has to be before it is trimmed, so natural pauses stay intact while genuine dead air disappears.

Tightening up silence makes episodes feel more professional and shaves minutes off the runtime without re-editing by hand. It is a common first pass before loudness normalization and final delivery.

Remove silence from audio automatically

It is the fastest way to remove silence from audio without opening a DAW. Set the threshold and the minimum gap, and the trimmer finds and cuts every stretch of dead air — leading, trailing and in the middle — in one pass. Whether you need to remove dead air from an interview, cut silence from a voice-over take or tighten the long pauses in a lecture, it leaves the speech untouched and drops only the gaps.

1. Upload the recording you want tightened, up to 10 MB signed out or 100 MB with a free account.

2. Pick a trimming mode: ends only, reduce long gaps, aggressive for a tight cut, or natural pauses for a light touch.

3. Download the trimmed file, then confirm it still passes loudness and noise checks in the Voice Quality Analyzer.
