How can I trim music?

You can adjust a soundtrack to a specific part of your project, by following these few steps:

1. Select and add a soundtrack from the Audio section, by tapping on the music note icon under your project preview. > Your song will appear in the Audio section as a red bar.
2. Tap on the white side handles of the red bar, hold your finger and move it to the left or to the right: this way you can set the length of the soundtrack and its starting point.
3. Then, by holding your finger on the red bar itself (not on the side handles) and moving it to the left or to the right, you can make sure that the soundtrack matches the clips you thought it for.
