FEATURES
● APPLICATIONS
— Pitch shift The LC83025E can shift the music pitch or the microphone pitch by ±15 steps in 1/4 interval steps, or ±1 octave in scale tone steps according to command data sent from the microcontroller. Furthermore, the pitch can be changed up to ±1 octave in arbitrary steps by setting internal coefficients. — Microphone echo The LC83025E implements echo processing for the signal input from the microphone A/D converter. The amount of echo, the delay time and other parameters can be changed by setting coefficients. — Voice mute The LC83025E implements processing that removes monaural signal components included in the music signal. This allows CDs with vocals to be used as karaoke CDs. Command data is used to turn the voice mute function on or off. — Simple surround The LC83025E implements a simple surround function by adding delayed components to the music signal. The LC83025E includes six sets of simple surround coefficients as built-in preset data. These values can be switched by sending command data.
