Patent ID: 8531994

Claim:
An audio processing method, comprising: receiving, by a control server, coded audio data sent by each terminal that accesses the control server; performing, by the control server, capability negotiation with each terminal to obtain audio capabilities of each terminal; and forwarding, by the control server, audio data extracted from the coded audio data to each terminal according to the audio capabilities in one of the following modes: if all terminals support multi-channel separation audio codec protocols, the control server selects multiple channels of audio data among the audio data to generate encapsulated data, and transmits the encapsulated data to each terminal through an audio logical channel; and if all terminals support multiple audio logical channels, the control server selects multiple channels of audio data among the audio data, and transmits the selected audio data to each terminal through the multiple audio logical channels; wherein if only one control server exists, the control server forwards the audio data extracted from the coded audio data to each terminal that accesses the control server according to the audio capabilities; wherein the selecting by the control server of the multiple channels of audio data among the audio data to generate encapsulated data, and transmitting of the encapsulated data to each terminal through the audio logical channel if only one control server exists and a terminal supports the multi-channel separation audio codec protocols comprises: selecting, by the control server, audio data of a plurality of terminals for audio mixing according to a preset policy; retrieving, by the control server, audio data in independent channels of the plurality of terminals; and encapsulating, by the control server, the audio data into a packet, and then sending the packet to each terminal through the audio logical channel; and wherein the selecting by the control server of the multiple channels of audio data among the audio data, and transmitting the selected audio data to each terminal through the multiple audio logical channels if only one control server exists and a terminal supports the multiple audio logical channels comprises: selecting, by the control server, audio data of a plurality of terminals for audio mixing according to a preset policy; and sending, by the control server, the audio data of the plurality of terminals to each terminal directly through the multiple audio logical channels.
