| Abstract: | Compared with the data acquisition card,the sound card has the following merits：low-price,easy-developing and flexible-system.In this paper,the design technology of hard—ware and software has been introduced in detail,including the background,the structure.On this base,the sound card and LabVIEW has been used to develop the audio signa1 acquisition and analysis system,which can be used to acquire and analyze the audio signa1.The system has better interface which can be maintained easily.In order to meet the need,the function of the system can be modified.It has been indicated in the application that the system has great sense in teaching and experiment. |
