Note: First-time loading of ffmpeg.wasm requires downloading core files (large), which may take time; all processing is done locally in the browser without uploading audio.
Note: This tool uses ffmpeg.wasm's silenceremove filter to automatically detect and trim silence. All processing is performed locally in your browser.
How to Use
- Click 'Select File' to upload your audio (supports MP3/WAV/AAC, etc.).
- Click 'Load FFmpeg' to initialize the core component (approx. 20MB, may take time).
- Set 'Trim Mode': Remove only start/end silence or all silent segments.
- Adjust 'Silence Threshold' (default -35dB) and 'Min Silence Duration' (default 0.2s).
- Click 'Start Processing', then 'Preview' and 'Download' the result.
Tips
- Powered by ffmpeg.wasm silenceremove filter. All processing is done locally.
- Adjust the threshold based on noise floor; lower values (e.g., -50dB) are stricter.
