BU8709KN

03W024A Melody sound source LSI for cellular phone BU8709KN Description BU8709KN is a melody sound source LSI for cellular phones. This LSI generates 64 high quality polyphonic tones through high sampling rate (fs=44.1KHz). 1 ADPCM encoder and 2 ADPCM decoders functions are embedded, providing mixing capabilities. It can customize output sounds by an equalizer function and display the signals by Graphic Equalizer. It also has Reverb function, as well as LED & Vib synchronization.
