How to play the ringtone on Apple's mobile phone 4s?

1. Right-click the song you want to be a ringtone in the iTunes music list, select "Show Introduction" and enter "Options", where there are "Start Time" and "End Time". You can intercept a piece of music as a ringtone at will. It should be noted that the bell should not exceed 40 seconds. Finally, click OK. If the original sound is too small, you can adjust the volume.

2. Right-click the music again and select "Create AAC Version". At this time, iTunes will automatically make music in ".m4a" format, and an intercepted music file with the same name will automatically appear in the list.

3. Right-click the converted music, select "Display in Windows Explorer", open the folder where the music is located, and find the location of the music. Because Apple's ringtone format is ".m4r", you need to change the extension of music from ".m4a" to ".m4r".

4. Double-click the music with the changed extension and play it in iTunes. ITunes automatically adds music to the Ringtones list. Click "ringtone" in the "database", and the list will display the music and related information just now.
