基于LabVIEW的鸟声信号分析系统

Birdsong Analysis and Identification System Based on LabVIEW

基于LabVIEW平台开发了一种具备多种分析功能且能够处理长数据文件的鸟声信号分析系统——Song Lab.重点介绍了系统设计开发中的关键点:多控件的组合应用,能够实现一些依靠单个控件无法实现的界面操作;长数据处理,有效地解决了长数据的读取效率问题,特征信息的处理,实现对特征信息的提取,分析和注释.并进行了实验分析,结果表明该系统分析结果精确,能够为从事动物声学领域的研究者提供较完善的技术支持.

Based on the LabVIEW platform,a birdsong analysis system -Song Lab which has variety of analysis functions and capacity to handle the large amount of data files is developed.Key techniques in this system are then comprehensively related with corresponding analysis and annotation in this paper：combination of multi -control applications,which can achieve some interface operations that a single control can′t achieve;large data processing,which can solve data reading efficiency problem;and the processing of feature information,which can realize the characteristics of information extraction.Finally,the practical application value is verified by acoustics experiment.The result shows the effectiveness and accuracy of this system,which can provide a good technical support for researches in the field of animal acoustics.
