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

Abstract

The invention discloses a sound mixing processing method of a sound amplification system. The sound mixing processing method comprises the following steps: determining an output volume value of each microphone according to a sound signal acquired by each microphone; determining an attenuation value corresponding to each microphone according to the output volume value of each microphone and the mixed output volume value of all the microphones, the larger the output volume value is, the smaller the attenuation value corresponding to the microphone is; and determining a target mixed output volumevalue of the sound amplification system according to the output volume value of each microphone and the attenuation value corresponding to each microphone. The invention further discloses a sound mixing processing device and a computer readable storage medium. According to the invention, volume attenuation is carried out on the microphones with relatively low output volume values in the sound amplification system, so that the comb filtering effect is greatly reduced when the sound fed back to the microphones by the sound boxes and picked up by the plurality of microphones is superposed to thedirect sound, positive feedback is not formed, and howling is avoided.

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.
