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.

Audio data receiving apparatus, audio data receiving method, and audio data transmission and receiving system

A transmission device includes: a communication unit performing communication with one or more receiving devices; a distance measurement unit measuring direct distances to the receiving devices; a transmission data setting unit setting transmission data including content data including audio and time information indicating the time when reproduction of content data is started for the receiving devices whose distances are measured based on the measured distances; and a transmission processing unit transmitting transmission data set by the transmission data setting unit to corresponding receiving devices of transmission targets all at once. The transmission data setting unit sets time when the device itself starts reproduction of the content data as a reference time, and sets the time information for synchronizing audio indicated by the content data reproduced in the device itself with audio indicated by the content data reproduced in the receiving devices for each receiving device using the set reference time.
