無音区間の削除

Clean pauses without leaving the browser

Silence Remover helps editors, podcasters, course creators, and voice-over teams shorten dead air before publishing. It is useful when long pauses make a recording feel slow, when meeting audio needs a tighter edit, or when a narrated track should fit a target duration.

Workflow

1. Upload an audio file or load the sample to see the detection controls.
2. Adjust Sensitivity, Min Silence Length, and Threshold until the highlighted regions match the pauses you want to remove.
3. Deselect any detected pause that should stay for pacing or emphasis.
4. Preview the trimmed version, choose an output format and bitrate, then export the final audio.

Option guidance

Start with a 0.5 second minimum for podcasts and tutorials. Use a shorter minimum for fast voice notes, and a longer minimum for interviews where natural pauses should remain. Raise the threshold or sensitivity when quiet room noise prevents silence from being detected; lower them when soft speech is being marked incorrectly. Fade In/Out prevents hard joins, while Normalize Output restores a comfortable peak level after pauses are removed.
