How to Trim an MP3 on Windows 11 and 10

Trim an MP3 in Five Steps

1. Open the MP3

   Choose File → Open… and select your audio file. Keep the original file as your source copy.

2. Select the Section to Keep

   Drag across the waveform to select the passage you want. Use the zoom controls and the Selection Start, End and Duration values to check the boundaries.

3. Listen to the Selection

   Listen around the beginning and end of the passage. Move a boundary if it cuts into a word or musical note.

4. Export Only That Selection

   Choose File → Convert / Export…. Set Source to Selection only, then choose MP3 under Format.

5. Save a New MP3

   Review the output settings and click Export MP3. Give the new file a different name, then play it to check the result.

Remove a Mistake Instead

To remove an unwanted part from the working audio, select that part and choose Edit → Delete. Listen across the edit and use Undo if the cut needs adjusting.
