Frequently Asked Questions

What is silence removal?

Silence removal is the process of detecting low-volume sections in an audio recording and either cutting them out, trimming only the edges, or splitting the file at each silent gap. Notevibes gives you all three options in one free browser tool so you can pick the right approach for each file.

What is the difference between the 3 silence modes?

Remove All Silence cuts every silent gap in the recording and re-stitches the audio into a single shorter file.Auto-Trim Edges only removes the leading and trailing silence while keeping the interior untouched.Split at Silence keeps the audio intact but creates one downloadable file per non-silent chunk, so silent gaps become natural split points.

How does silence detection work?

The tool uses an RMS-style amplitude threshold of 0.01 (roughly -40 dBFS) and requires at least 0.3 seconds of continuous low amplitude before a region is considered silence. This matches how most podcast and voice-over editors define a silent gap, so the results line up with what a human editor would mark.

Can I adjust the silence threshold?

Not in this simple version. The Notevibes silence remover is tuned with sensible defaults so you can process a file in one click. If you need a custom threshold or manual control, open the full audio editor for more advanced silence handling.

Is the silence remover free?

Yes. The Notevibes silence remover is completely free, with no sign-up, no watermark, no ads, and no limit on how many files you can process. Max file size is 200 MB per upload.

Is my file uploaded to a server?

No. The silence remover runs 100% in your browser using the Web Audio API. Your audio never leaves your device — nothing is uploaded, stored, or analyzed. You can even disconnect your internet after the page loads and the tool still works.

What audio formats are supported?

The silence remover accepts MP3, WAV, M4A, FLAC, OGG, AAC, WEBM, and OPUS files up to 200 MB. Output is always a 192 kbps MP3, regardless of the input format, so you get a consistent deliverable every time.

Does the silence remover work on mobile?

Yes. It runs on iOS and Android in Chrome, Firefox, Safari, and Edge. Tap to upload a file, tap a mode, tap Apply, and download the cleaned file directly to your device.
