VOICE CHANGER Features
‧ Wide operating voltage range 3.0V ∼ 5.0V ‧ and low power consumption. ‧ Several voice effects selectable -- Transposing voice (higher or lower) -- Amplifying voice -- Robot voice Low power consumption ‧ No need of external memory. ‧ Variable resistor or switch can be used to adjust the transposed voice effect. ‧ For applications in toy, mask, telephone system and other voice fields. ‧ With a silence function
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.
