Frequently asked questions
- How does silence detection work?
- The tool measures the volume of your audio in short chunks and treats anything below a threshold as silence. Long silent stretches get cut down (a little breathing room is kept at each edge so cuts don't sound abrupt); short natural pauses are left alone so speech doesn't sound choppy.
- Which sensitivity should I pick?
- Balanced works well for most recordings. Use Gentle if it's cutting pauses you wanted to keep, or Aggressive for a recording with a lot of dead air (like a raw podcast or interview take) that needs tighter editing.
- Will this cut off the start or end of my recording?
- Leading and trailing silence is trimmed more aggressively than pauses in the middle, since there's no surrounding speech to preserve rhythm against — but a small amount is always kept rather than cutting straight to the first sound.
- Is my audio uploaded anywhere?
- No — detection and processing both happen entirely in your browser. Nothing is uploaded.
How GetByteRush compares
Most free tools for this online work the same way: you upload your file to their server, wait, then download the result — which means your file (and often your email, for a "free" account) sits on someone else's infrastructure. Here's the actual difference:
| Feature | GetByteRush | Typical online tools |
|---|---|---|
| Data ever leaves your device | No — processed in this tab | Yes, uploaded to process |
| Keeps natural pauses, only trims long dead air | Yes | Varies — some tools cut every gap equally |
| Account required | Never | Often, past a certain usage level |
