Make ringtone from iRinger

Desktop app iRinger converts any video or music file into an iPhone ringtone, including YouTube videos. You already saw how to make a ringtone using only iTunes, but iRinger brings audio effects (like fade in and out, flanger, and delay) and video support to its single, simple interface. You can download any YouTube clip, for example, and import it into iRinger to create a tone. iRinger does nag you with a pop-up sponsor window that you can't close unless you donate to the project; otherwise it's a handy all-in-one iPhone ringtone utility. iRinger is a free download for Windows only.
