Frequently asked questions
- How do I remove silence from an audio file?
- Add the file and the quiet start and end are trimmed automatically. Switch on the gap option to also cut long pauses in the middle, then adjust the threshold if it is cutting too much or too little, and download.
- What does the threshold slider do?
- It sets the level below which audio counts as silence. A lower (more negative) value keeps faint detail and only removes true silence; a higher value cuts more aggressively, useful for noisy room tone you want gone.
- Will it cut the quiet words in my speech?
- It is designed not to. The tool leaves a little padding around the audio it keeps, and only removes stretches that stay quiet for a while, so natural pauses between words survive while the dead air at the ends and the long gaps go.
- Which formats are supported, and does my recording leave my device?
- It handles MP3, WAV, OGG and M4A, and exports the tightened track as MP3 or WAV. All of it runs in your browser on your device, so your recording is never uploaded to a server, and there is no watermark or account needed.
