3: Select the Options tab and then tick the Start Time and Stop Time boxes. Enter times at which you want the ringtone to start and stop. You will have to listen to the track first and note down the time you want it to start. The stop time must be within 30 seconds, as this is the maximum length for a ringtone.

The file will be highlighted. Right-click on it and choose Rename. Now change the extension from .m4a to .m4r. Click Yes when asked if you want to change the extension. If you can't see the extension, it's because Windows is set to hide the extensions. To show the extension for editing
