Authors describe how to develop device driver of multi-channel voice encoder using DDK and driver studio on windows 2000, and we discuss the stability of driver in the kernel-mode briefly. 讨论了在Windows2000下编写设备驱动程序的方法,给出了用DDK和DriverStudio开发多路话音采集压缩卡驱动程序的做法.论述了运行在内核模式中驱动程序的稳定性。
The DSP-ADPCM voice encoder is a new product of the Institute of Image and Graphics of Sichuan University, which is used for collecting and playing voices. DSP-ADPCM语音采集压缩卡是四川大学图形图象研究所新研制的集语音采集和回放功能于一体的硬件设备。
The system consists of three parts: platform for voice acquisition and processing, voice encoder and encryption algorithm. 该系统包含语音采集及处理平台,以及在其上实现的语音编码和加密算法。
