Claims

[Scope of utility model registration request]

An analog/digital converter that converts an analog audio signal into a digital signal, a random access memory that stores the digital signal, and a digital/analog converter that converts the digital signal read from the random access memory into an analog audio signal. In a pitch conversion device that performs pitch conversion of an audio signal by changing the frequency of a write clock signal that controls writing to the random access memory and a frequency of a read clock signal that controls reading, the read clock signal or A pitch conversion device comprising a clock signal output terminal that outputs a clock signal corresponding to a read clock signal.
