Sound mixing processing method of sound reinforcement system, sound reinforcement system and storage medium

Abstract

The invention discloses a sound mixing processing method of a sound reinforcement system, comprising the following steps: determining the output volume value of each of the microphones according to the sound signal collected by each of the microphones; value and the mixed output volume value of all the microphones to determine the attenuation value corresponding to each of the microphones, wherein the corresponding attenuation value of the microphone with the larger output volume value is smaller; according to the output volume value of each of the microphones, each The attenuation value corresponding to the microphone determines the target mixed output volume value of the sound reinforcement system. The invention also discloses a sound mixing processing device and a computer-readable storage medium. The present invention attenuates the volume of the microphone with a lower output volume value in the sound reinforcement system, so that when the sound picked up by multiple microphones is fed back to the sound box and superimposed on the direct sound, the comb filter effect is greatly reduced, and the Form positive feedback to avoid howling.

Description

technical field [0001] The invention relates to the technical field of acoustics, in particular to a sound mixing processing method of a sound reinforcement system, a sound reinforcement system and a storage medium. Background technique [0002] Traditional multi-microphone sound reinforcement systems are used in almost any mixing console, news broadcast, talk show, auditorium, film and television dialogue recording, or any discussion or meeting scene involving multiple microphone participants. Therefore, the traditional multi-microphone sound reinforcement system often needs to turn on multiple microphones at the same time in practical application scenarios. When the direct sound picked up and the sound fed back by the speaker are output from one output channel, the sound picked up by multiple microphones and fed back from the speaker will strengthen the direct sound, thus forming a positive feedback. When the feedback coefficient is close to 1 At this time, due to the com...

AI Technical Summary

Problems solved by technology

[0004] The main purpose of the present invention is to provide a control method for gain mixing, which aims to solve the technical problem that multiple microphones feed back the sound of the speaker to itself and superimpose the direct sound picked up by the microphone to form a positive feedback that causes the system to howl.
