Will it cut off breathy sounds?

Only if they fall below the dB threshold. Raise the threshold by 3–5 dB if the tool is too aggressive.

Does it leave clicks at the cut points?

The server keeps a short pad of silence at every splice — tune it with the preserve-gap slider. 100–300 ms feels natural for speech.

Can I preview before downloading?

Yes. The result plays in the built-in player before you download.

Why is this a server-side tool?

A 45-minute podcast has around 100 million samples per channel. Scanning and rebuilding that in-browser used to freeze Safari tabs, so the detection and re-encode now run on our servers and the result comes back in your original format.

How to use Silence Remover

Drop a file
Drag an MP3 or WAV. The original waveform renders immediately.
Set the threshold
Anything quieter than this dBFS level is treated as silence. Default -40 dB works for most speech.
Set the minimum duration
Runs shorter than this are kept, so natural pauses are not chopped.
Set the preserve gap
The tool leaves this much silence in place where it removes a gap, so edits do not sound clipped.
Remove silence
The file is processed on our servers and returned in the same format.
