<p>A method, a device and a system for mixing processing of an audio signal are provided in the embodiments of the present invention. The method includes: judging a channel type of a receiving terminal; for a single-channel receiving terminal, sending a mixed audio signal and meanwhile sending location information of a sending terminal that has maximum audio signal energy on each sub-band of the mixed audio signal to the single-channel receiving terminal; for a double-channel receiving terminal or a multi-channel receiving terminal, performing up-mixing to obtain double-channel or multi-channel audio data according to location information that is allocated to a single-channel sending terminal, performing mixing processing on audio data that participates in mixing to obtain double-channel or multi-channel mixed audio data, and sending the double-channel or multi-channel mixed audio data. With the solution provided in the embodiments of the present invention, in a mixing system of receiving terminals with multiple channel types, a location sense of each sending terminal that participates in mixing exists, thereby improving an on-the-spot feeling of an audience in a complicated mixing situation.</p> |
