There is an way of making custom ringtones for iPhone using only iTunes. However, you can only follow this method to make iPhone ringtones using DRM free music in iTunes library. If you want to custom a .m4r ringtone with protected iTunes M4P or DRM protected WMA music, you'll have to turn to a DRM removal software to get it DRM free first. What's more, if you are fond of some audio/sound clip from a video file and want to set it as your iPhone ringtone, the iTunes method fails to help too. What's going to do next?

ImTOO iPhone Ringtone Maker comes to the rescue! This piece of iPhone ringtone creator software can help you turn virtually any music/sound source into iPhone .m4r ringtone. It can also trim audio clips from video files (in all popular video formats) as iPhone ringtones. Now let's take a look at the detailed steps:

1. Download ImTOO iPhone Ringtone Maker from http://www.softdiggs.com. Install and launch it.

2. After the main interface pops up, click the "Browse" button to select the video or audio file with which you want to custom an iPhone ringtone from the dialog box that pops up and then click the "OK" button. You will see the file path and name are displayed in the "Input File" text box.

3. Click the "Play" button to listen to the music before creating an iPhone ringtone and locate the part you really want, then drag and drop the start & end sliders to get the music clip. Or you can directly input the start & end time in the "Start Time" and "End Time" text boxes respectively.

4. Set output folder by clicking the "Browse" button on the right side of the "Local Output File" label.

5. If you want ImTOO iPhone Ringtone Maker to help you transfer the ringtone to iPhone directly after conversion, check the "Export to iPhone" option.
