摘要
以美国国家仪器(NI)公司开发的LabVIEW虚拟仪器为软件开发平台,设计了一个可以同步实现声音信号采集和分析的多功能模块化软件系统.借助LabVIEW图形化软件相应的声音读取、写入和存储函数实现对声音信号的采集、存储、时域分析和频域分析,并实时显示在工作前面板上.该系统在试验中得到了很好的验证,为将来对声音信号进一步分析与处理提供了理论支持.
By using the LabVIEW graphical programming software, a sound signal acquisition and analysis system was reported. Based on the corresponding functions in LabVIEW, sound signals can not only be read, written, and stored, but also analyzed both in time-domain and frequency-domain. A friendly man-machine interface was also designed for the real-time data. The system has been experimentally confirmed working well and may be helpful for future railway industry.
