C++6.0实现语音采集与播放的控件。souce code 中为该程序的源代码 由于编写该控件的过程中用到了Directx8.1 所以需要安装 Directx8.1sdk 在路径中加入所需的lib exe 中的 ocx 用之前需要用regsvr32 进行注册 如果机器安装的Directx版本低与8.1的话不能运行 该控件没有对语音包压缩 所以对网络环境要求比较高 该控件在校园内经过性能测试-C 6.0 Acquisition and voice broadcast controls. China souce code for the program"s source code because of the preparation of the controls used in the process of Directx8.1 Directx8.1sdk therefore need to install the path to join the lib exe randomly with the use regsvr32 required before registration if machines installed DirectX version 8.1 with low so can not run the Controls no compression of voice packets so the network environment to the high demand on the campus of control after performance testing
