Low power consumption

General Description

The RTS0072B is a single chip CMOS LSI designed for voice changer, which can

transpose or distort one voice into another voice by encoding the input audio signals in

normal speed and transmit the output audio signals with unusual speed. That is

accomplished by sampling the input audio signals into digital signals and re-arranges the

digital signals to generate different voice from the user normal voice.
