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.
The Realtek RTS0072B is a single-chip CMOS LSI designed for voice changer applications. It encodes input audio signals at normal speed and transmits output signals at unusual speeds by sampling and re-arranging digital signals. This allows the device to transpose or distort one voice into another, suitable for use in toys, masks, telephone systems, and other voice fields. The chip operates with a wide voltage range of 3.0V to 5.0V and requires no external memory.
