Description: MCI虽然调用简单，功能强大，可以满足声音文件处理的基本需要，但是MCI也有它的缺点，那就是它一次只能播放一个WAVE文件，有时在实际应用中，为了实现混音效果，需要同时播放两个或两个以上的WAVE文件时，就需要使用微软DirectX技术中的DirectSound了，该技术直接操作底层声卡设备，可以实现八个以上WAV文件的同时播放。-simple, powerful, voice processing documents to meet the basic needs, but MCI also has its shortcomings, it is only once a player WAVE documents, sometimes in practical application, in order to achieve mixing effects, need to play two or more WAVE documents, it is necessary to use Microsoft's DirectX technology DirectSound, and the technology underlying direct audio equipment operation can be achieved over eight WAV files at the same time players.

Description: 由于在局域网中有足够的带宽，不需要对语音数据进行压缩，因此语音通信主要包括语音的采集、传输和播放。其中语音的采集与播放使用DirectSound接口实现，语音传输使用UDP协议实现。在多人语音通信时还需要DirectSound的混音功能。为了增强软件的实用性还要求软件能够自动获取在线用户列表，以简化用户的操作。-As the LAN has enough bandwidth, no need to compress voice data, so voice communications include voice collection, transmission and playback. Speech acquisition and play them using the DirectSound interface, voice transmission using the UDP protocol. Voice communications in multiplayer DirectSound mixing functions will also be required. To enhance the usability of software also requires the software to automatically obtain the online user list, in order to simplify the user' s actions.
