Problems solved by technology

After using this method for mixing, the volume of each sound will be reduced to 1 / n of the original, which will cause the above-mentioned volume to become smaller and the sound quality to become unclear; if the superimposed value is not divided by n, it is easy to have a loud noise or distortion

Abstract

The invention discloses a sound mixing method, a related device and a computer storage medium, and the method comprises the steps: obtaining sampling information, voice data of input equipment, and voice data of output equipment; determining voice delay time between the input equipment and the output equipment based on the sampling information, the voice data of the input equipment and the voice data of the output equipment; and processing the voice data of the input equipment and the voice data of the output equipment by using the voice delay time to generate sound mixing data. Therefore, according to the embodiment of the invention, the voice data of the input equipment and the output equipment can be subjected to voice mixing based on the occurrence position of the maximum voice intensity value in one frame of audio data, so that the problems of distortion or attenuation or excessive quantity possibly caused by direct addition of corresponding position data in the prior art are avoided, therefore, the user of a remote client can hear real and effective voice information.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a sound mixing method, a related device, and a computer storage medium. Background technique [0002] In application scenarios such as online teaching, remote conferences, and online voice chats, there are often problems such as audio distortion after mixing the sound of the microphone and the playback sound, or excessive attenuation of the mixing volume, which affects the user experience. [0003] In the prior art, each channel of PCM (Pulse Code Modulation, pulse code modulation) data collected back is directly superimposed, and then the superimposed value is divided by the superimposed number n. After using this method for mixing, the volume of each sound will be reduced to 1 / n of the original, which will cause the above-mentioned volume to become smaller and the sound quality to become unclear; if the superimposed value is not divided by n, it is easy to have a lo...
