Sound mixing system and method capable of automatic distributing gains

Abstract

The invention discloses a sound mixing system and method capable of automatic distributing gains. The sound mixing system capable of automatic distributing gains comprises a collection module, a detection module and an order module; the collection module is connected to each sound pickup module and each power amplification module and is used for collecting a first audio frequency signal from each sound pickup module and collecting a second audio frequency signal outputted from the power amplification module; the detection module is connected to the collection module and is used for performing comparison detection on a degree of coherence of a first audio frequency signal and a second audio frequency signal which are collected at the same time in order to determine the coherence of the first audio frequency signal and the second audio frequency; the order module is connected to the detection module and is used for transmitting a gain distribution order according to a coherence result determined by the detection module in order to make the gain distribution module change an output gain of the audio frequency signal collected by each pickup module connected to the gain distribution module according to a gain distribution order. The sound mixing system and method capable of the automatic distributing gain can prevent mutual interference between audio frequency signals among multiple microphones in the sound mixing system, improves a voice output effect of the sound mixing system and enhances a voice output effect of the sound mixing system.

Description

technical field [0001] The invention relates to the field of reverberation equipment, in particular to a sound mixing system and method for automatically allocating gains. Background technique [0002] In public places such as conference rooms or stadiums, when holding meetings or organizing collective activities, it is often necessary to set up a sound mixing system to amplify the sound that needs to be amplified. However, due to the limitations of the venue, the sound emitted from the sound mixing system speakers is often blocked and reflected by the surrounding buildings, and is collected and amplified again by the sound pickup device of the sound mixing system within a very short time after it is emitted. The above situation may cause the sound broadcast by the mixing system to be confusing, making it difficult for people to understand. What's more, it will produce howling phenomenon, which will make the speakers of the mixing system scream and affect the user's experien...
