| Abstract: | Since the audio analysis instrument of hardware is expensive,has long maintance period and is hard to be expanded,this paper uses LabVIEW to design the audio analysis instrument,which uses sound card and virtual instrument.It includes the audio acquisition,the audio parameters measuring and the audio spectrum analysis,etc.Test result implies that the audio analysis instrument has enriched the computer network experiment functions and achieved vivid images and good visual effect |
