Synthetic music mobile application format
Synthetic-music[1] mobile application format, abbreviated SMAF, is a music data format specified by Yamaha for portable electronic devices, such as cell phones and PDAs. The file extension for SMAF is .MMF and is common as ringtones for mobile phones with one of five sound chips.
SMAF resembles MIDI, but also supports graphics and PCM sound playback. Its MIDI playback is produced via FM synthesis or PCM wavetable synthesis, where instrument data (parameters and/or PCM samples) is stored within the .MMF file itself, similar to module files. This enables users to create custom instruments, which will sound exactly the same on devices with the same chip.
There are five major versions of SMAF: MA1, MA2, MA3, MA5, and MA7.

- ^ smaf-yamaha.com spells it Synthetic music Mobile Application Format, with the word "music" not capitalized so it does not participate in the abbreviation SMAF. However one editor expressed concern that this odd capitalization pattern would confuse readers, so a hyphen is used here instead.
