摘　　要：采用声卡代替商用数据采集卡,利用Visual C++软件编程技术,设计了基于声卡的双通道实时信号采集处理系统,该系统能够实现25kHz范围内双路信号的实时采集、实时分析,所采集数据的存储和网络发送等功能,系统实用性较强,可广泛应用于各高校实验室及实时语音信号处理等领域。This article aims at the design of double-channel real-time signal collecting and disposal system based on sound card by means of replacing commercial data collecting card with sound card, with the application of Visual C＋＋ software programming technology. This system is capable of the real-time collecting, analysis, storage and online transmitting of the double-channel signals within the range of 25 kHz. And the author believes that this system is of high practical applicability which ensures its full use in university laboratories and other certain fields like real-time voice signal deposal.
