Drop in a recording and this audio silence remover online free finds every stretch of dead air, shows you exactly what it is about to cut on the waveform, and gives you the file back without it. Or flip one switch and split audio by silence online into numbered parts — part-01, part-02, … — downloaded as a ZIP. No account, no watermark, no upload: your files never leave your device.
Cutting audio at an arbitrary sample leaves a vertical step in the waveform. That step is a broadband transient and your ears hear it as a click or a tick — the number one complaint about free silence removers. This tool applies a 5–10 ms fade in and fade out at every single cut point, so the signal always passes smoothly through zero. You can even set the fade length yourself. It costs nothing and it is the whole difference between a usable export and one you have to fix in an editor.
Drop an MP3, WAV, M4A, OGG or FLAC file (up to 30 minutes). It is decoded in your browser and drawn as a waveform.
Move the threshold, minimum-silence and padding sliders. The red regions update instantly, and the summary tells you how much will be removed.
Pick "Remove silences" for one clean file or "Split on silence" for numbered parts, choose WAV or MP3, process, listen, download.
Search for one and the results are almost entirely AI voice-cloning companies. For them a silence remover is a lead magnet: deliberately shallow, capped, and gated behind a sign-up so they can pitch you a subscription. Meanwhile the largest genuinely free browser audio toolset does not even list a silence remover. That gap is why this page exists — a real tool, complete, with no account and no upload.
Yes. No sign-up, no account, no watermark and no per-file limit. Most silence removers you find are lead magnets for paid AI voice products and ask you to register first. This one does not — it runs entirely in your browser.
No. Decoding, silence detection, cutting and encoding all happen inside your browser with the Web Audio API. Your files never leave your device, which is also why there is a length limit.
Because they cut the waveform at an arbitrary sample. If the level jumps from -0.4 to 0 in one sample, that step is a broadband transient — you hear it as a click or tick. This tool applies a 5-10 ms fade in and fade out at every cut point, so the level always moves smoothly through zero. That is the single most common quality complaint about cheap silence removers.
Decoding audio in the browser expands it to raw 32-bit samples: one hour of stereo is roughly 1.2 GB of RAM. To keep the tab from crashing the limit is 30 minutes, and about 12 minutes on iPhone and iPad Safari, which has a much lower memory ceiling. For longer recordings, split the file first.
For a clean voice recording, -40 dB with a 500 ms minimum works well. If your room is noisy, raise the threshold toward -30 dB so room tone counts as silence. If natural pauses are being eaten, raise the minimum silence to 700-1000 ms and increase the edge padding so the speech does not sound rushed.
Yes. Choose Split on silence and every stretch of audio between two silences becomes its own numbered file — part-01, part-02 and so on — downloaded together as a ZIP. It is the fastest way to cut an interview, a set of takes or a batch of voice-over lines apart.
