Abstract

The embodiment of the invention discloses a sound mixing method, device, equipment and medium for an online meeting. Wherein, the method includes: if the audio mixing data trigger event is detected, obtaining the recording clients in the recording state among the participating clients; selecting the audio mixing client from the recording clients according to the number and priority of the recording clients; Perform audio mixing processing on the voice collected from the audio mixing client to obtain conference audio mixing data. The embodiment of the present invention can dynamically use different sound mixing strategies according to different numbers of recording clients, which solves the problem of high performance consumption when the meeting voice is mixed by the participating clients; at the same time, the sound mixing efficiency is effectively improved, so that the participants can have a higher degree of participation experience.

Description

technical field [0001] The embodiment of the present invention relates to a data processing technology, and in particular to a sound mixing method, device, device and medium for an online meeting. Background technique [0002] With the rapid development of Internet technology, applications based on streaming media technology such as web conferencing and Internet telephony have been widely used in people's lives; in multimedia conferences, participants need to hear the voices of multiple speakers. The voice signal of each speaker will be transmitted to each participant separately, and then played after mixing at the terminal, so that each member participating in the conference can receive the voice of the speaker. [0003] The disadvantage of the above solution is that each terminal will occupy a large amount of network bandwidth when mixing audio, and has high requirements on terminal performance; thus resulting in low audio mixing efficiency and reducing the conference expe...
