Terminal audio channel processing method and device and terminal

The invention provides a terminal audio channel processing method and device and a terminal. The method comprises the steps that when the terminal is connected, the horizontal angle, detected by a gyroscope, of the terminal is obtained; the snatching mode of the terminal is determined according to the detected horizontal angle; corresponding audio channels are selected for communication according to the determined snatching mode, and the audio channels comprise a left channel with a telephone receiver and a microphone on the left side of the terminal and a right channel with a telephone receiver and a microphone on the right side of the terminal. Through the terminal audio channel processing method and device and the terminal, the problems that in the related technology, due to the fact that the snatching habit of a user is unstable, the performance of the audio channels cannot be achieved well, and consequently user experience is reduced are solved, the good audio channels are selected according to the snatching mode, the optimal effect of audio frequency is effectively achieved, and the effect of improving the user experience is achieved.
