Problems solved by technology

[0004] For common audio mixing algorithms, after configuring the number of audio mixing channels, all the configured audio data will be mixed. In the case of large background noise, when the number of audio mixing channels exceeds a certain number, the audio mixing effect will be very good. Poor, it's hard to hear what's being said

Abstract

The present invention provides a sound mixing method and system for a conference system, including calculating the voice energy of the voice signal of each member's voice input terminal in response to detecting the voice signal of each member; based on the voice energy and the preset first The threshold value divides each member into the first set and the second set, wherein, the members whose voice energy is greater than or equal to the first threshold value are grouped into the first set, and the members whose voice energy is less than the first threshold value are grouped into the first set. Set to the second set; in response to the difference between the maximum value of the voice energy in the second set and the minimum value of the voice energy in the first set is greater than or equal to the preset second threshold value, the maximum value of the voice energy in the second set The member of is replaced with the member of the minimum value of speech energy in the first set, and the first set and the second set are updated; the speech signals in the first set are mixed and synthesized and output. Based on dynamic grouping, the output of meaningful voice signals is guaranteed, and audio quality is avoided due to excessive noise.

Description

technical field [0001] The invention relates to the application field of computer technology, in particular to a sound mixing method and system for a conference system. Background technique [0002] The full English name of MCU is multi control unit, multi-point control unit. In order to realize the multi-point conference TV system, MCU must be set. The MCU is essentially a multimedia information switch, which performs multipoint calls and connections, realizes functions such as video broadcasting, video selection, audio mixing, and data broadcasting, and completes the tandem and switching of various terminal signals. The difference between the MCU and the current switch is that the switch completes the point-to-point connection of signals, while the MCU completes multipoint-to-multipoint switching, tandem or broadcast. [0003] With the development of network communication technology, the research and application of multi-person voice system has become one of the current ...
