Mark the passage
- Open Free MP3 Cutter Joiner and keep Cut MP3 selected. Choose Add files and open your MP3.
- Select the file and choose Trim clip. Drag the two waveform handles, or enter the Start time and End time.
- Use Preview start edge and Preview end edge to hear the boundaries. Zoom in when you need a closer view.
- Choose Apply trim to keep the range in the project. The source file stays intact.
Save a separate MP3
Keep MP3 selected in Export, choose your output name, and click Export Cut. You can add a short fade in or fade out in Advanced before exporting.
If several tracks are loaded, Cut MP3 exports the selected track only. Switch to Join MP3 when you want to combine the queue.
Leave room around the sound
For speech, start just before the first syllable and let the final word finish naturally. For music, listen for the beat or note you want at the boundary. A small timing adjustment often sounds better than cutting by sight alone.
Check the saved passage
- Listen to the beginning and end of the exported MP3.
