Problems solved by technology

[0002] In practice, there are often scenarios of multi-person conversations, such as multi-party conferences. However, due to the limited ability of the human ear to identify mixed signals from different sound sources at the same time, it is usually necessary to mix the sound signals from different participants. , to highlight the limited number of voices. In addition, the call quality needs to be considered at the same time. In practical applications, the call quality of multi-person calls is mainly affected by network packet loss. Due to the instability of the transmission network, packet loss occurs during the transmission process, resulting in The sound of the receiving end is stuck and incoherent. In related technologies, repeated multiple transmissions are mainly used to avoid network packet loss. Repeated multiple transmissions are to copy multiple copies of the original data packets and send them to the receiving end at different time intervals. It needs to consume additional bandwidth. How to effectively control the multiple of repeated multiples, reduce bandwidth consumption and ensure call quality is very necessary

Embodiment approach

[0090] The first implementation mode: server audio mixing solution. Among them, in the server audio mixing solution, the server periodically obtains the downlink audio mixing signal of each downlink audio channel according to the sound signal of each uplink audio channel and sends it to the corresponding call participating terminal, and then the call participating terminal can obtain the corresponding downmix signal and play the downmix signal.

[0091] It specifically includes: S1. Respectively determine the mixing weights of the downmixing signals of the downlink audio channels of each uplink audio channel except the corresponding downlink audio channel.

[0092] In the embodiment of this application, the sound mixing scheme is based on the processing in the time domain. After the server decodes the sound signal in the time domain, it can use the sound mixing algorithm to calculate the downlink sound mixing signal of each downlink audio channel, for example, Taking the i-th...

Abstract

The present application relates to the field of communication technology, and in particular to a multi-person call control method, device, electronic equipment, and storage medium, respectively acquiring the sound signals of each uplink audio channel, wherein each uplink audio channel, downlink audio channel and call participation One-to-one correspondence between terminals; respectively determine the packet loss rate of each uplink audio channel; determine the mixing contribution of each uplink audio channel according to the participation of each sound signal in the downmix signal of each downlink audio channel degree; according to the packet loss rate and the mixing contribution of each upstream audio channel, respectively obtain the target repetition multiplier of each upstream audio channel, so that, in combination with the packet loss rate and the mixing contribution, determine the final The target repeats multiple multiples, realizing the reduction of bandwidth consumption while ensuring the call quality of multi-person calls.
