How to Remove Silence from Audio in 3 Steps
Drop a recording
Drag any MP3, WAV, M4A, OGG or FLAC onto the left pane. The waveform makes the quiet gaps easy to spot.
Tune the detection
Open Settings: anything below the threshold (−40 dB works for most voice recordings) for at least the minimum length counts as silence. Padding keeps a little air at each edge so words are not clipped.
Remove and download
Click Remove silence. The badge reports how many gaps were cut and how much time you saved; listen to the result and adjust if it sounds choppy.
Silence Remover — Frequently Asked Questions
Is my audio uploaded anywhere?
No. The file is decoded by your browser's Web Audio engine, processed on your device and encoded to MP3 or WAV with an open-source encoder running in the page. Nothing is sent to a server.
What threshold should I use?
Start at −40 dB. If background hiss is being kept as speech, raise it (−30 dB); if quiet words are being cut, lower it (−50 dB). Padding of 0.1–0.2 s stops the result sounding clipped.
Does it remove silence in the middle, or only at the ends?
Everywhere. Every gap longer than the minimum is removed, leaving the padding on each side. Set a longer minimum (1–2 s) if you only want to lose the long pauses and keep natural breathing.
Which formats can I open and save?
Open anything your browser plays: MP3, WAV, M4A/AAC, OGG, Opus, FLAC and WebM audio. Save as MP3 (128, 192 or 320 kbps) or lossless 16-bit WAV. Pick the format under Settings before you run the tool.
How long does it take?
Processing is near-instant; MP3 encoding runs at roughly 15× real time, so a 5-minute song takes around 20 seconds. The progress bar shows the encode.
