How to trim and join audio online
- Add audio files. They appear consecutively on the shared timeline.
- Drag blocks to move them and drag their edges to trim. Overlapping clips play together. Select a block to adjust its volume and fades.
- Preview the montage, choose a format and click Save file. Then download the result.
To trim an MP3 or another recording, keep just the clip you need in the assembly. To remove a section from the middle, add the clips before and after it.
Editor formats and features
