SMAF is the data format specification designed by YAMAHA, which has a main purpose to define the data expression of the multimedia contents for mobile device (mainly used in cellular phone). The basic portion of SMAF specification is designed to play the sound data conveyed by YAMAHA LSI sound chip. It is now mainly used as an the ringing alert melody of a cellular phone.
SMAF also supports an extended feature which can define display sequences of texts and graphics. SMAF can synchronize the sound sequence with pictures and texts easily. With this feature, it is now used as data expression of the multimedia contents including Karaoke. Moreover, since SMAF has a very flexible structure like a container, SMAF has a specification which can be expanded for future use.
