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.
