About this tool

Keep just the chorus of a song, the useful part of a recording or the start of a podcast. Drop the file, drag on the waveform to choose the section, play it, add a fade, then save it in the format you want.

When to use it

Grab a chorus

Keep your favorite part of a song for an edit, a presentation or a ringtone.

Clean up a recording

Remove the silence or noise at the start and end of a voice note or interview.

Prepare a clip

Cut a few seconds of a podcast to share on social media.

How to use

  1. Drop an audio file or a video.
  2. Drag on the waveform to set the start and end.
  3. Set the fade in and fade out, then play the section.
  4. Choose the format and save.

How it works

The file is decoded in your browser with the Mediabunny library, and the waveform is drawn from the samples. The chosen section is cut to a tenth of a second.

Fades raise and lower the volume gradually. The section is then encoded to MP3, M4A, WAV, OGG or FLAC on your device: nothing is uploaded.

Tips for best results

  • A 1 to 2 second fade out avoids an abrupt ending.
  • Keep WAV or FLAC to edit the sound further without loss.
  • Play the section before saving to check the boundaries.
  • For a phone ringtone, use “Ringtone maker”.

Common problems and fixes

The file isn't read

Some rare formats aren't supported: convert the file first, or try a recent browser.

M4A or OGG is rejected

Your browser can't encode it: choose MP3 or WAV.

The waveform is flat

The sound may be very quiet or missing: check the original file.

Frequently asked questions

Can I cut the sound of a video?

Yes, drop an MP4, MOV, WebM or MKV video: only its sound is kept.
