RTS0072
VOICE CHANGER
RTS0072B
‧ 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
‧ 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
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.
