采用PC技术、DSP技术和LABVIEW多线程技术，实现了对音频信号实时、高保真的采集与处理。系统性价比高，通用性强，界面友好，数据存储方便，性能稳定可靠，其个别性能指标甚至优于市售数据采集板卡。在PC上配置多块声卡并行工作，完全可以构成一个多通道数据采集系统，满足特定应用范围内数据采集的需要。-PC technology, DSP technology and LABVIEW multithreading technology, to achieve real-time audio signal. High Fidelity acquisition and processing. High system cost performance, versatility, friendly interface, data storage convenience, performance is stable and reliable. their individual performance even better than the commercial data acquisition device. On the PC sound card and over the allocation of parallel work, it is entirely possible to create a multi-channel data acquisition system, meet specific application within the scope of data collection needs.
