M4R: the ringtone file used in Apple iOS
The M4R format is used in Apples mobile devices, mostly for storing ringtones. You can create an M4R file by converting other formats or downloading it from the official iTunes store. The sound conversion employs a special type of compression, which significantly reduces the file size. The advantages of this format make it ideal for iPhone owners. M4R is one of the constituents of the standardized MPEG-4 format. One of its strong points is that the high sound quality is fully preserved after compression.
