Information about the .m4r (m4r) file type

Below is all the information we have available on file about the .m4r (m4r) file type.

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).

Where this is available we would like to include file format information on .m4r files, as well as information on how to view or open files of type .m4r. If you know of any information which we have missed then please let us know.
