摘要
目前在因特网上实现音频传输的效果还不是很理想,而局域网却足以传输高质量的音频数据。我们利用VisualC++设计了一个能够应用于局域网的多点语音实时通信系统。该系统包括语音采集、压缩编码、网络传输等主要模块。试验结果表明,本系统在局域网中传输稳定、通信可靠,能够完成语音实时通信,有着潜在的应用价值。
At the present time INTERNET is not good at audio data transmission.LAN can transmit audio data very well because of its enough bandwidth.We design a realtime speech communication system applied in LAN with Visual C++.The modules of sampling,compression,transmission and so on are included in this system.The computer simulation result indicates that the rea1 time communication can be performed stable and reliable in this system and the system has the potential value for LAN application.
