The invention provides a audio data inflexion method. The method comprises the following steps: the step A, a terminal sends out the inflexion parameter to a media server; the step B, the media server sends out inflexion request receiving information to the terminal; the step C, the terminal sends out the audio data flow to the media server after receiving the inflexion request receiving information; the step D, the media server carries out inflexion processing after receiving the complete inflexion data cell; the step E, the inflexion processing is stopped when the condition that the inflexion can be stopped is satisfied, or else, the step C is repeated until to the step D. the invention uploads the audio data on the terminal to the media server in a network, the media server carries outthe inflexion processing for the audio data, and the processed audio data is real-timely transmitted to the terminal, thereby enabling any terminal which has the network access capability to carry out the inflexion processing to the audio data in the fastest and most convenient way.
