The M4R audio format is Apple's exclusive ringtone format designed for the iPhone. Using iTunes, you can turn on any song in your music collection into a 30-second M4R ringtone and transfer it to your iPhone for free. Since M4A files function like all other audio files on your computer, you can also send them via e-mail or transfer them over the web, which takes very little time since most M4A files require less than 1 Mb of space.

Open iTunes and access your "Preferences." If using Windows, click "Edit" on the menu bar and select "Preferences" from the drop down list. If using Mac OS X, click "iTunes" on the menu bar and select "Preferences" from the drop down list.
Click the "General" tab--indicated by an image of a light switch--and select "Import Settings."
Click the option that reads "AAC Encoder," in the "Import Using" field at the top of your window. Click "OK" in the lower right corner of your "General" window, and then in the lower right corner of your main "Preferences" window.
Click "Music" in the left column. When your song list appears, right-click any song title to access a list of options. Choose a song that you would like to convert into an M4R ringtone. When the list appears, select the "Get Info" option.
Click the "Options" tab and change the numbers appearing in the "Start Time" and "End Time" fields. An M4R ringtone must be 30 seconds or less, so choose a brief snippet of your song. For example, if the songs chorus begins at the one-minute mark and lasts for 26 seconds, you would enter "01:00" into "Start Time" field, and "01:26" in the "End Time" field, to preserve only the chorus. Click "OK" when you finish.
Click the song title once to highlight it in your "Music" folder. Click "Advanced" on your menu bar and choose "Create AAC Version" from the drop down menu. The amended version will also appear in your "Music" folder. When it appears, drag it on your desktop using your mouse.
Change the extension of your new song. Your title will appear with an "M4A" extension--for example, "Over The Rainbow.m4a." Double-click the title and use your keyboard to replace the letters "m4a" with "m4r." Apple will now recognise the file as a ringtone.
Send your ringtone via e-mail. If you want to send one more of these files to a friend or to another computer using e-mail, open your e-mail client or web server, create a new message (using the "Compose" or "New Message" option) and click "Add Attachment." Select your ringtone file using the navigation menu and click "Send."
Send your ringtone using a file upload service. If you do not want to use your personal e-mail, just visit a site like RapidShare, SendSpace or YouSendIt and use the "Upload" form to select your ringtone file from your desktop. Enter a recipient's e-mail address in the designated field and click "Upload" or "Send."
Send your ringtone to your iPhone. First drag your M4R file back into iTunes. Connect your iPhone to your computer using your USB sync cable, select the "iPhone" icon in iTunes, click the "Ringtones" tab and check the box that reads "Sync Ringtones." You can choose to sync all ringtones in your iTunes library, or select only the one you want.
