Claim Text:
1. An audio mixing method, comprising: receiving, from a first site, a first audio stream that comprises a first plurality of sound source objects; receiving, from a second site, a second audio stream that comprises a second plurality of sound source objects; receiving, from a third site, a third audio stream that comprises a third plurality of sound source objects; analyzing the first audio stream to obtain a sound characteristic value of each of the plurality of sound source objects; analyzing the second audio stream to obtain a sound characteristic value of each of the second plurality of sound source objects; analyzing the third audio stream to obtain a sound characteristic value of each of the third plurality of sound source objects; selecting, according to a descending sequence of sound characteristic values of the first plurality of sound source objects, the second plurality of sound source objects, and the third plurality of sound source objects, a predetermined number of sound source objects from the first plurality of sound source objects, the second plurality of sound source objects, and the third plurality of sound source objects to serve as main sound source objects, wherein a portion, but not all, of each of the first plurality of sound source objects, the second plurality of sound source objects, and the third plurality of sound source objects are selected as main sound source objects for audio mixing, and wherein a sound source object that is not selected as a main sound source object in an audio stream that contains a main sound source object is muted without muting the main sound source object or the audio stream; determining each site selected from among the first site, the second site, and the third site from which each of the main sound source objects were received in an audio stream; determining a target site selected from among the first site, the second site, and the third site; determining audio streams that require audio mixing as audio streams received from each site selected from among the first site, the second site, and the third site, but not the target site, from which each of the main sound source objects were received in the audio stream; and either performing audio mixing on the determined audio streams that require audio mixing for the target site, and sending the audio streams after the audio mixing to the target site; or sending to the target site the determined audio streams that require audio mixing for the target site to perform audio mixing in the target site.
