Audio Silence Remover
Strip leading, trailing and mid-track silence from an audio file, entirely in your browser via ffmpeg.wasm.
Recordings often have dead air at the start, the end, or in awkward mid-track pauses that make them feel unpolished or drag out run time. This tool uses FFmpeg's silence detection, running locally via WebAssembly, to find sections quieter than a threshold you set and cut them out automatically. It's useful for cleaning up voice memos, podcast raw takes, or field recordings before you trim or merge them further with the Audio Trimmer or Audio Merger.

Common questions
What does the threshold mean?
Audio quieter than the threshold (in dB) is treated as silence. Lower (more negative) values are more aggressive.
Does it upload my audio?
No - processing runs locally with WebAssembly.
Will it remove silence in the middle of a track, not just the ends?
Yes - it detects and removes silent segments throughout the file, not only the leading and trailing edges.
Could it cut off quiet speech by mistake?
A threshold set too aggressively can clip soft speech along with true silence. Start with a moderate threshold and adjust based on the result.
