The steps to cut a section of music are as follows:

1. Open the editing software on your computer and enter the main interface.

2. Click Audio Edit and select the music you want to edit.

3. Then you can slide the audio track and select the tool below to edit.

4. The mouse now changes to a dotted line, click on the unnecessary beginning in the middle of the audio, and then click on the split again.

5. Click at the end of the unnecessary middle to divide the current audio into three segments. If the split position is not accurate, you can drag the timeline to listen first, stop at the appropriate position, and then use the dividing line to merge with the timeline.
