PCM Sound Generation Technology
FueTrek Co., Ltd. provides our melody LSIs with Sound Generator IP(Intellectual property) for mobile phones. The Sound Generator IP is PCM Sound Generator which provides more realistic sound quality, and it includes the Double Wave Table system and the Tone Split system.
Double Wave Table system
The Double Wave Table system is the technology which generates the tone of a musical instrument with two Wave Tables. Deep and rich sounds are generated by overlaying the basic Wave Table and the pitch shifted Wave Table.
Tone Split system
The Tone Split system is the technology which uses Wave Tables optimized for a certain range of key. An acoustic musical instrument does not have a uniform waveform by the height of a key. By choosing the Wave Table suitable for the key, natural sounds can be created.
