Synchronous audio playback method, apparatus and system
A synchronous audio playback method, apparatus and system are provided. The method includes calculating a first playback delay generated when an audio file is played; acquiring a second playback delay; calculating a delay offset; calculating a data adjustment amount; adding to-be-adjusted data to or deleting to-be-adjusted data from a current to-be-played part of the audio file according to a value of the delay offset, to obtain a replacement part corresponding to the current to-be-played part, where a data amount of the to-be-adjusted data is the data adjustment amount; and playing the replacement part. With the technical solutions of the present invention, playback duration of a current to-be-played part can be adjusted in a manner of adding or deleting data, so that a controlling device and a controlled device generate sounds simultaneously when playing a to-be-played clip in a very simple implementation process.
