Free Audio Silence Finder

    Decodes the file, measures RMS in short windows, and reports stretches quieter than your threshold for longer than your minimum. The waveform shows the hits. The download is a cut list, not an edited file — this does not rewrite the audio.

    Your files never leave your device

    This is not a promise about how carefully we handle your upload. There is no upload. The file you choose is read into memory by your own browser, processed there, and handed back as a download — the tool has no server component and makes no network request with your data.

    • Nothing is stored. We never receive the file, so there is no copy to retain, no retention period to disclose, and nothing to delete on request.
    • Nothing is transmitted. No upload endpoint, no analytics payload carrying file contents, no third-party processor.
    • You can verify it. Load this page, disconnect from the internet, and use the tool. It still works, because everything it needs is already on your machine.
    • Nothing persists after you close the tab. Files are held in page memory only — not in local storage, not in a cache, not in a database.

    A note on wording, because it matters: we do not describe these tools as “encrypted.” Encryption protects data that travels to somebody else's computer. Your file does not travel, so there is nothing to encrypt and nothing to intercept — which is a stronger guarantee than encryption, not a weaker one. The page itself is served over HTTPS like the rest of the site.

    This makes the tools safe for material you are contractually barred from uploading to third-party services — client footage under NDA, unreleased campaign assets, anything covered by a confidentiality clause.

    Questions

    It marked room tone as silence, or missed a pause. Why?

    Silence here is RMS below a dB threshold, not 'no one is talking'. Room tone, a noisy street, and a compressed podcast all sit at different floors. Drop the threshold for a quiet pause in a noisy file; raise it if ambience is being flagged. Always check the waveform before you cut.

    Can this delete the silences for me?

    No. The browser can decode, but splicing compressed audio without a click at every join is an editor's job. The CSV is timestamps you can paste into one. Treating auto-silence-removal as a one-click clean-up is how you lose breaths that were doing work.

    Do my files get uploaded anywhere?

    No. This tool runs entirely in your browser using the Canvas and File APIs. The file you choose is read into memory on your own machine, processed there, and offered back as a download. Nothing is sent to a server, which is also why it keeps working with your network off.

    Is it actually free, or is there a catch?

    Actually free, with no account and no limit, because it costs nothing to run — the work happens on your device rather than on our hardware. That is different from generating with an AI model on Versely, which does cost credits; there is no free tier for generation.

    These rearrange files. Versely makes new ones.

    Everything on this page works on a file you already have, which is why it costs nothing. Generating something that did not exist — video from a prompt, a voice, a score — runs a model, and that costs credits.
