Problems solved by technology

Among them, the server mixing is to send the voice signals of all the clients participating in the multi-person call to the server, and the server uses the voice signals sent by other channels to perform mixing processing according to the needs of each channel. The server needs to perform multiple mixing processing. Mixing processing costs a lot and requires high server processing capability

Abstract

The invention provides an audio mixing method, a server and clients. The audio mixing method comprises the steps that first audio signals sent by all the clients are received; the received first audiosignals are subjected to full audio mixing processing to obtain full audio mixing audio signals; and the full audio mixing audio signals are sent to all the clients, so that the clients filter the first audio signals subjected to full audio mixing processing from the full audio mixing audio signals so as to obtain audio mixing audio signals carrying the first audio signals, subjected to full audio mixing processing, of other clients to be played. Through the audio mixing method, the first audio signals of the clients on all channels are subjected to audio mixing only through one-time audio mixing processing, and the cost of audio mixing processing is lowered greatly while the audio quality is ensured.

Description

technical field [0001] The present application relates to the technical field of audio processing, in particular to an audio mixing method, server and client. Background technique [0002] Mixing refers to the process of linearly superimposing audio signals from multiple sources. With the increasing demand for group social interaction, more and more scenarios require multi-person voice calls, such as multi-person audio and video conferencing, multi-person online live broadcast, multi-person real-time voice chat in online games, etc., to achieve multi-person voice calls The core technology is sound mixing. [0003] The existing audio mixing technology can be divided into server audio mixing and client audio audio mixing according to the audio mixing subject. Among them, the server mixing is to send the voice signals of all the clients participating in the multi-person call to the server, and the server uses the voice signals sent by other channels to perform mixing processi...
