一个改进的混音算法

An Improved Mixed Audio Algorithm

为了支持企业协同工作,语音工具应提供自由发言等灵活的发言权控制方式.现有的语音工具由于混音效果不理想,通常只能采用发言权轮转这种简单的发言权控制方式,限制了群体成员的交互.该文介绍作者设计实现的一个语音工具——ENVoice所采用的旨在提高混音质量的混音技术.该技术的应用,对于支持协同工作具有重要意义.

In order to support cooperative work in enterprise environment, voice tool should provide flexible floor control mode. Because mixed audio is not clear in existing voice tools, they have freezing floor control mode only where members talk by turns which limits the free discussing among group. In the paper, a new mixed audio algorithm, which improves voice quality, adopted by voice tool ENVoice (Enterprise Network Voice tool) is provided. It is very important to support cooperative work.
