摘要
在基于S IP的多媒体会议系统环境下,设计了一种自适应衰减的混音算法,并将该算法在VC环境下编程实现.测试结果表明:该算法能够有效地解决多用户下的音频溢出等问题,可提高语音质量,满足会议的要求.
This paper designs a adaptive attenuated audio mixing arithmetic in multimedia conferencing system, which is basing on sip, and this arithmetic had been implemented in VC environment. The result of the test indicate that the arithmetic can resolve audio overflow problem under multiuser,improve the audio quality,meet the conferencing requirements.
