Quick answer
To remove a part of an audio file, load it, select the unwanted section on the waveform, make sure “Remove selection” is active, and click Preview to hear the joined result. When it sounds right, export as MP3 or WAV. The audio before and after the selection is merged into one file.
How to use the Remove Part of Audio
- Load the fileOpen the recording that contains the part you want to delete.
- Select what to removeDrag across the unwanted section; it turns grey to show it will be removed.
- Preview the joinPress Preview result — playback skips the selection so you hear the final edit.
- ExportDownload the edited file as MP3 or WAV.
Making the join sound natural
Place both edges of the selection in a moment of silence or between words. If the join still clicks, move each edge by ±0.1 s until the transition is smooth. For music, cut on the beat — the waveform peaks show where drum hits land.
Common uses
- Removing filler words, coughs or long pauses from podcasts.
- Deleting a spoken intro or outro from a lecture recording.
- Removing a radio ad break from a recorded show.

Frequently asked questions
Can I remove several parts?
Yes — export once, click “Keep editing”, or reopen the exported file and remove the next section. Each pass is instant.
Will there be a gap where I removed audio?
No. The audio before and after the selection is joined directly with no gap.

Yes. Every feature — cutting, fading, volume, speed and MP3/WAV export — is free with no sign-up, no watermark and no daily limit. The site is supported by unobtrusive ads.
Are my files uploaded to a server?
