Trimming audio precisely

Recordings rarely start and end exactly where you want. There is silence before the speaker begins, a cough in the middle, or a long tail after the music finishes. An audio cutter lets you keep just the section you need by choosing a start and end point.

FlashFile accepts any format your browser can decode — MP3, WAV, M4A, OGG, FLAC and more — and exports the selected part as a WAV file so no additional compression is added.

Common uses

Ringtones and alerts

Cut the best 20–30 seconds of a song for a ringtone.

Podcasts and interviews

Remove silence and false starts from the beginning and end.

Clips for social media

Extract a short quote or highlight from a long recording.

Music practice

Isolate a passage to loop and learn.

Getting clean edits

Start and end your selection in a quiet moment between words or notes to avoid an abrupt click. For a smoother result, add a short fade-in and fade-out with the Audio Fade tool.

Making the file smaller

The trimmed audio is saved as WAV. Convert it with WAV to MP3 if you need a smaller file to share.
