An audio reproduction circuit has an input buffer for holding MP3 data. The audio reproduction circuit also has an MP3 decoder for reading and decoding, in certain processing units, the MP3 data held in the input buffer, and generating voice data. The audio reproduction circuit also has an output buffer for holding the voice data supplied from the MP3 decoder. The audio reproduction circuit also has a digital-analog converter for reading the voice data from the output buffer in synchronization with a clock signal, and converting the voice data to an audio signal. A cut-out detector is provided for generating a cut-out detection (prediction) signal on the basis of the quantity of MP3 data remaining in the input buffer and the quantity of voice data remaining in the output buffer. The cut-out signal indicates a timing at which MP3 data is to be introduced to the input buffer.
