What is the .M4R File Extension?

.M4R File Extension Description:

Audio files for ringtones created for the iPhone employ the M4R file extension. M4R file extensions contain tailor-fitted ringtones produced with Apple iTunes and are automatically transmitted to the user's iPhone if the device is synchronized with user's computer.

Apple iTunes permits users to modify actual tracks to suit their own tastes and employ them as ringtones for their iPhones by storing them in M4R file extensions and sending them to their iPhones. The user has more than 500,000 songs to choose from at the Apple iTunes store. Upon purchasing a song, the user alters it to generate a ringtone and pay the same price paid for the song of the ringtone, with the right to own both song and ringtone forever. This is done by selecting an acquired song in the library indicated with a ringtone icon, employing the ringtone editor to establish fade in, playback delay or fade out, and then clicking on it to purchase it.

M4R file extensions are transmitted to the iPhone through Bluetooth - a direct link such as a USB connection, e-mail, or text messaging.

The user also crafts distinct ringtones for the various callers for easy identification. This is all made possible by the iTunes Store with music files formatted with Advanced Audio Coding (AAC) for high-quality audio. Prospective buyers are permitted to a 30-second preview of a song before they decide to possess it forever and later utilize it as the basis for an iPhone ringtone in the M4R file extension format. There are also more than two million songs available through iTunes Plus. These songs are not restricted by DRM technology and users are not prohibited to play them in various devices.
