中文摘要:
      研究目的:当前已有大量研究人员使用基于LabVIEW的虚拟声频信号分析系统开展研究工作,LabVIEW正在成为声频信号测量分析的主要研究手段,但是现有成果均使用了以频率为代表的物理声学单位,没有同时提供在音乐实践常用的音分标记法,影响了研究成果的普适性。方法:通过分析频率与音分的转换方法,使用LabVIEW为平台编写频率与音分转换应用。结果:编写了基于LabVIEW的频率与音分转换应用,应用运算稳定,适用性好。结论:基于LabVIEW的频率转换音分应用设计方便了物理声学单位转换为音乐声学单位,便于研究成果能够推广到更广泛的声学研究中去。
英文摘要:
      A large number of researchers carry out research work based on LabVIEW virtual audio signals analysis system. LabVIEW has become the main means of measurement and analysis of audio signals. However, physical acoustics units were used in existing results, such as frequency. It is not always consistent with subjective judgments of human ear. By analyzing the frequency-cent conversion, the applications of that were written for the platform using LabVIEW. It is shown that the applications based on LabVIEW are stable and applicable. The design of the frequency-cent conversion based on LabVIEW is convenient for the conversion from physical acoustic to musical acoustic units. It can be used to facilitate musical acoustics research by others.
