What counts as silence?

Any audio segment whose peak amplitude falls below the selected threshold percentage is classified as silence. A 5% threshold means only very quiet passages are removed; a 20% threshold removes anything quieter than 20% of the file's peak amplitude.

How should I set the threshold?

Start with a low threshold (around 5–10%) and increase it if too many quiet sections remain. Avoid setting it too high as you may accidentally clip the end of spoken words.

What does the minimum duration setting do?

It prevents natural short pauses (like breaths between sentences) from being cut. For podcast editing, 500–1000 ms is a good starting point.

Is this useful for podcasts and lectures?

Yes. Silence removal is one of the most popular podcast post-production steps. It tightens pacing and reduces file size by eliminating dead air and over-long pauses.

Is my audio uploaded to a server?

No. All processing happens locally in your browser using the Web Audio API. Your file never leaves your device.

How to Use

1
Upload your audio file
Click 'Choose File' or drag and drop your audio onto the upload area.
2
Set the silence threshold
Adjust the threshold percentage — any audio below this amplitude level will be treated as silence. A lower value is more selective; a higher value is more aggressive.
3
Set the minimum silence duration
Enter the minimum length (in milliseconds) a silent segment must be before it is removed. This prevents short natural pauses from being cut.
4
Click Remove Silence
Hit the Remove Silence button. The tool scans the audio, identifies silent segments, and splices them out.
5
