## How to remove silence from an audio recording

1. Drop an audio or video file on the box.
2. Set the silence level and the shortest pause to cut, or leave the level on automatic.
3. Listen to the result, then download it as a WAV.

## Questions

### How does it decide what is silence?

It measures every 20 ms slice of sound. Slices quieter than the silence level count as silent, and a run of them is a pause once it lasts as long as the shortest pause you set. Auto puts the level 6 dB above the quietest tenth of the recording, within −60 and −20 dB.

### Why does each cut keep some silence?

Cutting every moment of silence makes speech sound rushed and words run together. The padding keeps a little silence on each side of a cut, so the rhythm still sounds natural.

### Will the cuts click?

Each join is blended over 10 ms with an equal-power crossfade, so the edges of a cut stay smooth. The result is a 16-bit WAV at the recording’s own sample rate.

### Is my recording uploaded?

No. The file is decoded and cut in your browser, and nothing is sent anywhere. From a video only the sound is used, so the result is an audio file.
