The silence remover automatically detects stretches of low or no signal in an audio file and trims them, leaving a more compact and dynamic result. It's especially useful for podcasts with long pauses, voice recordings with silence between sentences, or any audio weighed down by empty stretches. Upload your MP3, WAV, OGG, FLAC, M4A or AAC file, adjust the volume threshold considered silence and the minimum duration it must last to be removed, and download the result. All processing runs with FFmpeg compiled to WebAssembly inside your own browser — your file never leaves your device.

Frequently asked questions

Is my audio uploaded to a server?

No. Everything runs with FFmpeg compiled to WebAssembly inside your browser. The file never leaves your device.

Does it also remove internal silence, not just at the start and end?

Yes, it removes any silence stretch that meets the configured threshold and minimum duration, wherever it is in the audio.

Can it cut off words if I speak quietly?

If the threshold is too high (close to 0 dB) it could mistake quiet speech for silence. Lower the threshold (more negative) if you notice it cutting parts it shouldn't.

What formats does it support?

MP3, WAV, OGG, FLAC, M4A and AAC. The result downloads in the same format as the original file.
