Sound mixing method and device, terminal and readable storage medium

Abstract

The invention discloses a sound mixing method and device, a terminal and a readable storage medium. The method includes: acquiring voice signals of all parties to be mixed, and calculating the ratio of the voice signals of all parties based on the principle of optimal signal-to-noise ratio of the mixing signals. The first sound mixing weight is used to perform sound mixing processing by using the voice signals of all parties and the first sound mixing weights of the voice signals of all parties to obtain a sound mixing signal. Compared with the prior art, the first mixing weight of the speech signals of all parties is determined during mixing by the optimal principle of signal-to-noise ratio of the mixing signal based on mixing, so that the signal-to-noise ratio of the mixing signal after mixing is Optimum, that is, maximization, wherein, the optimal principle of the SNR of the mixing signal makes the mixing weight of the speech signal with a smaller SNR correspondingly smaller, and the mixing weight of the speech signal with a larger SNR is correspondingly The larger the value, the influence of the noise of the voice signal used for mixing on the mixed mixed signal after mixing is reduced, and the call quality of the multi-party call is improved.

Description

technical field [0001] The present invention relates to the technical field of audio, and in particular, to a sound mixing method and device, a terminal and a readable storage medium. Background technique [0002] Mixing refers to the process of mixing the audio of multiple people into a mixed signal in a multi-party call scenario. Mixing is mainly used in multi-party call scenarios such as voice conferences and online multi-person chats. [0003] Multi-party calling is an important communication requirement in both traditional telecommunication network communication and Voice Over Internet Protocol (Voice Over Internet Protocol, VOIP) communication applications. During the multi-party call, each call party uses the terminal device to access voice, and sends the voice signal to the mixing module. The function of the mixing module is to mix the valid voices of other parties except the target party to be sent. And send the mixed signal to the target party, so that the user of...
