Abstract: An audio file playing method and an apparatus are disclosed and are used to: when an audio file is played, expand a quantity of audio channel signals in the audio file and improve a playing effect of the audio file. The method is as follows: after the audio file is obtained, determining, whether the audio file includes an audio channel signal that can be played by the mobile device; if the audio file includes the audio channel signal that can be played by the mobile device, directly playing the audio channel signal. Therefore, when multiple mobile devices are used to play a same audio file, the mobile devices can avoid performing a same operation, thereby increasing a quantity of audio channels of the audio file, expanding a sound field of the audio file, and improving a playing effect of the audio file.

Abstract: 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.
