An audio data receiving apparatus includes a receiving unit configured to receive audio data sampled in accordance with a first clock signal; a synchronization unit configured to generate a second clock signal that is synchronized with the first clock signal by extracting clock components contained in the audio data; a demodulator configured to demodulate the audio data in accordance with the second clock signal; an oversampling unit configured to oversample the audio data demodulated by the demodulator by using a frequency higher than a frequency of the second clock signal; a clock generator configured to generate a third clock signal having a frequency nearly equal to the first clock signal; and a data output unit configured to output the audio data oversampled by the oversampling unit in accordance with the third clock signal generated by the clock generator.
