Click on the "Options" tab and set the start and stop times for your ringtone. Your ringtone should be no longer than 30 seconds.
Click "OK" to save your changes.
Right-click on the song again and select "Create AAC Version." This will create a new copy of the song with the start and stop times you selected.
Right-click on the new copy and select "Show in Finder" (Mac) or "Show in Windows Explorer" (PC).
Change the file extension of the new copy from ".m4a" to ".m4r." This will convert the file into a ringtone.
Double-click on the new file to add it to iTunes.
Sync your iPhone or iPod Touch with iTunes and the new ringtone should appear in your device's settings under "Sounds & Haptics."
Select the new ringtone as your default or assign it to a specific contact.
