If you want to set your favorite song as your ringtone, you can purchase the ringtone version of the song online or through your iPhone. However, there is a way to create custom ringtones out of any tune in your personal music library. Here's how you can do it:
You can create your own ringtones out of your own music collection
- Open iTunes on your computer and find the song you'd like to turn into a ringtone.
- Find the part of the song you want to use as a ringtone. (You might want to use a stopwatch to time the point in the song you want the ringtone to begin and end. The cropped song should be no longer than 30 seconds.)
- Right-click on the song name and click Info.
- Click on the Options tab.
- Type in the start and stop times of your ringtone in the minutes:seconds format and make sure your ringtone isn't longer than 30 seconds. Click OK.
- Right-click the song name again and select Create AAC Version. iTunes will create a duplicate version of the song.
- Right-click the song and select delete. iTunes will prompt you with the "Are you sure…" screen. Click Remove.
- iTunes will also prompt you with an option to keep the files on your computer. Click Keep Files.
- Go to your computer's music folder and find the song file. It will usually be under Music > iTunes > iTunes Music; under the band's name folder.
- Right-click the song name and select Rename.
- Change the song's ".m4a" extension to ".m4r". Press Enter.
- Double click on the song name to play it through iTunes. The song will automatically show up on the iTunes Ringtones library on the left panel.
