Abstract: An audio mixing method, apparatus and system, which can ensure sound quality after audio mixing and reduce consumption of computing resources. The method includes: receiving an audio stream of each site, and analyzing the audio stream of each site to obtain a sound characteristic value of a sound source object; selecting, according to a descending sequence of sound characteristic values of sound source objects, a predetermined number of sound source objects from the sound source objects to serve as main sound source objects; determining, according to a relationship between a target site and the sites where the main sound source objects are located, audio streams that require audio mixing for the target site; and performing audio mixing on the audio streams that require audio mixing for the target site and sending the audio streams after the audio mixing to the target site.

Abstract: A method and an apparatus for playing audio of an attendant at a remote end and a remote video conference system are provided. The method includes: receiving audio of an attendant at a remote site; and by means of two or more loudspeakers mounted at a top and a bottom of a remote image presentation device at a local site, simulating an audio transmission path of the audio of the attendant at the remote site between the two or more loudspeakers and an attendant at the local site through a predetermined algorithm, where the simulating means that the audio transmission path is simulated between an image of the head of the attendant at the remote site displayed in the remote image presentation device, and the head of the attendant at the local site.
