About Audio Noise Reducer
Audio Noise Reducer is a free online audio tool that runs entirely in your browser. There is nothing to install and no account to create: open the page, use the tool, and download the result. Because all processing happens locally on your device (via WebAssembly), your files and text are never uploaded to any server.
How to use Audio Noise Reducer
- Drop your audio file (MP3, WAV, OGG, M4A…) into the upload area.
- Adjust the threshold if needed — higher values silence more.
- Click Reduce noise and download the cleaned WAV file.
