How noisy the place was. It sets what counts as silence.
Shorter pauses stay so that speech keeps its natural rhythm.
A little silence stays before and after words so they are not clipped.

Removing silence: questions and answers
Does the quality get worse?
Sound — no: it is copied as is, bit for bit. Video has to be encoded again to cut exactly on pauses: without re-encoding it can only be cut at key frames, which come every 1–10 seconds. We keep the resolution and frame rate and use at least the original bitrate, so the difference is not visible.
How are pauses detected?
We measure loudness every 10 ms. Stretches quieter than the silence level and longer than the shortest pause become cuts, minus a small margin around speech so words are not clipped.
What if a cut removes something important?
Click it on the timeline and choose “Keep this part”, or untick it in the list. You can also drag its edges or listen to it before cutting.
Which formats are supported?
MP4, MOV, WebM, MKV, MP3, WAV, M4A, FLAC, OGG and more, and the result keeps the original format. Rare formats such as AVI or WMA are processed in compatibility mode and saved as MP4 or FLAC.
Are my files uploaded anywhere?
No. Everything happens in your browser on your device; there is no server that receives files.
Is there a length limit?
Only your device’s memory. An hour-long recording is fine on a computer. Audio files take seconds; video takes about as long as compression.
