Remove Silence from Audio
Automatically detect and cut silent gaps from an audio file, free and processed entirely in your browser.
About Remove Silence from Audio
Long pauses, dead air, and silent stretches make a podcast or voice recording feel slower and less polished — cutting them out by hand means scrubbing through the whole waveform. This tool finds them automatically and cuts them out in one pass.
Adjust the silence threshold and minimum gap length to match your recording — background noise varies a lot between a phone recording and a studio mic. A small buffer is kept around every cut so words don't sound clipped. Everything runs locally in your browser using the Web Audio API; your audio is never uploaded to a server.

Frequently Asked Questions
How does this tell silence apart from quiet speech?
Same detection logic as the video version — loudness measured in small windows, only sustained gaps above your minimum duration get cut.
Will cuts sound abrupt?
No — a small buffer is kept around every cut point.
What if the defaults don't work well for my recording?
Adjust the threshold and minimum gap length to fit your recording's noise level.
Is my audio uploaded anywhere?
No. Detection and re-encoding both happen entirely in your browser.
