What is a M4R file?
M4R is another extension of the M4A format, used specifically for iPhone ringtones. It contains AAC-encoded audio and is designed to be easily imported into iOS devices via iTunes. In most cases, M4R files are short clips extracted from longer M4A or MP3 songs.
Despite being almost identical to M4A in structure, the M4R extension helps iTunes and iPhones recognize the file as a ringtone rather than music or podcast content.
How to open M4R files
M4R files are used for iPhone ringtones and can be played or transferred using iTunes. On most systems, VLC and QuickTime can also open them directly.
