You can quickly convert music from your iTunes library into an iPhone ring tone by transcoding a selected portion of the song from the standard audio format to the iPhone ring tone format. Once the song has been converted, simply change the file extension and transfer the ring tong file to your iPhone. You can then access the ring tone and set it as the default tone or enable it for specific contacts.
Click "Start," "Programs" and then "iTunes."
Right-click the song you wish to convert to an iPhone ring tone and select "Get info."
Click the "Options" tab.
Set the "Start Time" and "End Time" values to reflect the portion of the song you want to use as a ring tone. Then, click "OK." Ring tones for the iPhone can be a maximum of 40 seconds long.
Right-click the song and select "Convert Selection to AAC." This will create a new song that is displayed in your iTunes library.
Right-click the new song in your iTunes library. Select "Delete" and then click "Keep Files" when prompted.
Click "Start" and "My Documents." Navigate to the "Music\iTunes\iTunes Music" folder.
Open the folder containing the song you just converted to the AAC format. The folders are organized by artist.
Right-click the "M4A" file created during the iTunes conversion process and then click "Rename."
Change the file extension from "M4A" to "M4R" and press "Enter."
Double-click the M4R file to open it in iTunes and add it to your list of available ring tones. The file will be transferred to your iPhone the next time you sync.
- It is not possible to convert music purchased from the iTunes store to iPhone ring tones because DRM-protection prevents audio transcoding of these files.
