Yamaha SMAF Player: MA-series ringtone playback reconstruction

Yamaha SMAF Player reconstructs ringtone playback associated with Yamaha MA-series sound chips in C++. It parses SMAF MMF containers, decodes HandyPhone and Mobile scores and Yamaha voice data, and renders FM synthesis with optional ADPCM samples. The author based the parser and synthesizer on the public SMAF format description and examination of real files.
