Noise Gate
Reduce background noise between phrases with a soft noise gate.
Ready to choose a file. Engine loads on demand.
Technical details
Browser-local FFmpeg WebAssembly worker, Canvas and Web Audio. Single-worker fallback does not require SharedArrayBuffer. Files are not retained after reload.
How to use this tool
- Choose your source file using the labeled file button.
- Review metadata, preview and the relevant destination settings.
- Start processing and keep this page open.
- Download or share your finished file from the completion dialog.
Supported files and device limits
Common audio inputs include MP3, WAV, FLAC, M4A/AAC, OGG and Opus when the bundled engine can decode the codec. Images: JPEG, PNG and WebP. Convert HEIC to JPEG first. Large sources, long podcasts and 4K exports can exceed browser memory. Try a shorter clip or lower resolution if an export fails.
Privacy and troubleshooting
Source media stays in this browser session. The engine downloads from jsDelivr on first use; the provider receives ordinary connection information but no source media from these tools. Only non-sensitive destination preferences are saved locally. Retry after an engine error, close memory-heavy tabs or try a different browser. No higher-resolution setting can restore detail absent from your source.
Accessibility
Controls have text labels, timelines use numeric time fields, and downloads open in a keyboard-accessible dialog. Accessibility information and issue reporting.
Using a noise gate well
A noise gate lowers the volume when the signal falls below a threshold, which quiets hum, room noise or breaths between phrases. It does not remove noise that happens at the same time as speech or music.
Step by step
- Choose a file and preview the first 10 seconds.
- Set the threshold just above the background noise level.
- Use a fast attack so words start cleanly, and a slower release so endings are not cut off.
- Preview again, then export.
Tips
- If words sound chopped, lower the threshold or lengthen the release.
- Gentle ratios sound more natural than hard gating.
- Record in a quiet room first; a gate is a finishing step, not a fix for loud noise.
Screen-reader tips: every control has a text label, and progress and completion messages are announced in a live region, so you can keep your focus where it is. Use the heading keys to jump between the file, settings and results sections. Your file is processed in this browser and is not uploaded to the server; it is gone when you reload the page.
