.m4r file extension
- A .m4r file is a ringtone file for an iPhone (from Apple Inc).
The file is an MPEG-4 (compressed audio) file with some extensions specific to Apple. A .m4r file contains audio data intended to be used as a ringtone.
Purchased .m4r files are typically protected DRM. There are utilities available on the internet which will allow you to generate a .m4r ringtone file from other audio files (and these typically are not protected).
Can you add to this? Do you know of any applications not already listed which will work with .m4r files, view .m4r files or open .m4r files?
