Abstract: The present invention discloses a synchronized audio playing method, apparatus, and system for playing audio synchronously. By outputting designated data using a designated data buffer area before arrival of the starting time point of synchronous playing so as to make an audio link in a stable state, the method shuns from the impact of factors like system process scheduling interruption and system hardware on synchronous playing, thereby enhancing the precision of synchronous playing; moreover, upon arrival of the starting time point of synchronous playing, by computing a tuning amount of the audio data in the local synchronization buffer area, adjusting the audio data in the local synchronization buffer area according to the tuning amount, and meanwhile performing output playing on the tuned audio data, the method achieves audio synchronization play. Compared with the prior art, the present invention needn't add playing timestamp information to an audio data stream, and the playing terminal needn't process timestamp information during the entire playing procedure, thereby effectively increasing the flexibility of synchronous playing.
