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.
