    The MMF stands for Mobile Music File. The MMF files within a smartphone contain system ringtones, sound and can also contain graphics and text display. The MMF further contains three types of instrument parameters including FM, PCM, and Stream PCM. These file formats are compatible with the Windows system platform. Usually, Microsoft Mail supports MMF files. These files are much smaller in size compared to standard MIDI format files.
