s104, encoding the first sound data and the second sound data;
s106, the coded first sound is sent according to a first path, and the coded second sound data is sent according to a second path.
It should be noted that the first sound data is sound data collected by a preset terminal, and may be sound data of a host or sound data of a preset speaker, and the second sound data is sound data of a preset terminal playing a preset audio, and may be sound data of ppt or video. For example, when there are a plurality of speakers, the first sound data may be sound data collected by terminals where the plurality of speakers exist, and when there is only one speaker, the first sound data may be sound data collected by a terminal where the speaker exists. The device for collecting the sound by the terminal can be a microphone or other audio collecting devices. The preset terminal can be set by a person skilled in the art according to actual needs.
It is worth mentioning that in the voip conference, the host hopes to share the own desktop video and the PPT picture and also share the video and the PPT sound played by the host. When the voip conference is used, participants of the conference basically enter conferences in different places, and a host often plays videos and demonstrates PPT in a desktop sharing mode, so that the method is greatly helpful for the development of the conference.
The terminal may collect the first sound data and the second sound data first, and then the terminal performs encoding processing on the first sound data and the second sound data according to a predetermined protocol and type to obtain encoded sound data. And then, sending the encoded first sound data according to a first path, that is, sending the sound data to a server, and sending the sound data to a terminal device for playing after being processed by the server, where the terminal device may be multiple terminal devices, or may be a preset terminal device, such as a terminal device where a host or a speaker is located. And sending the second sound data according to the second path, namely directly sending the sound data to the terminal equipment. For example, the host side may send two data streams (microphone data and shared sound data), where the microphone data is forwarded to the sound mixing server for sound mixing and then is delivered to the participant side, the shared sound data is directly forwarded to the participant side without passing through the sound mixing server, and the participant side receives the two data streams (microphone sound mixing data and shared sound data delivered by the sound mixing server), then performs sound mixing and finally plays the data streams.

It should be noted that, the collected first sound data often includes echo data, so that filtering processing is required. The server collects a plurality of first sound data; and identifying the first sound data, and filtering echo data. After the echo data is filtered, the speaking sound of the terminal is preset, in order to keep the real-time performance and experience feeling of a conference, when a plurality of people speak, the speaking sound of each person needs to be played, the sounds are combined to obtain first mixed sound data, and then the first mixed sound data is sent to a plurality of terminal devices to be played.
