How to extend the ringtone of Apple mobile phone for 30 seconds?

1. Select the song you want to be the ringtone in the iTunes music list (please use the shortcut key Ctrl+S to open the left sidebar for the new iTunes), and right-click and select "Show Introduction"; Enter "options", including "start time" and "stop time", randomly intercept a time period less than 45 seconds (generally, only "stop time" is selected and "0:30" is filled in), and click OK. If you think the original sound is low, you can also adjust the volume.

2. After confirming the settings, right-click the music again and select "Create AAC Version". This means that iTunes will automatically help you make music in ".m4a" format, and a music with the same name will automatically appear in the music list, which will be grayed out before the conversion is completed, and there will be voice prompts after the conversion to restore normal display.

3. Select the converted music in the list, right-click, select "Display in Windows Explorer", open the folder where the music is located, and find the music location.

4. Change the extension of music from ".m4a" to ".m4r" (this is the ringtone format of iPhone), then double-click the music and play it in iTunes, and iTunes will automatically add the music to the ringtone list. Click "ringtone" in the library to see the music in the list, and the list can display information such as ringtone duration.
