数字混音模型的设计与实现

Design and implementation of digital mixing model

混音是VoIP系统中的一个关键环节,通过对现有常用的混音算法的分析比较,引入声音音量这一对声音质量有较大影响的因素参数。在此基础上,改进了权重系数混音算法,从而提出了一种权重系数补偿混音算法。该算法运算复杂度较低,混音效果清晰、自然、流畅,避免了音量大小及突变等问题,可广泛应用于各类VoIP系统中。

Mixing is a key point in VoIP system.By analysis and comparing with existing mixing algorithms,the sound volume of factor parameters is introduced,which influenced the quality of sound greatly.Then,a weight factor compensation mixing algorithm is proposed by improving the weight factor mixing algorithm.This algorithm has lower computing complexity and causes more obvious,natural and smooth mixing effects.It avoids the size and mutation of volume and is applied into various types of VoIP systems widely,which get the promotion of a certain significance.
