However, sound card as a data acquisition card, possesses the advantages of low cost, developing easy and system flexibility, etc. This paper has discussed and designed a data collection and analysis system by taking sonic card of the computer as data acquisition card and MATLAB as the software platform. This paper has specifically introduced the background of this topic, the structure and the characteristics of nowadays data collection system and gives a systematic analysis of the hardware and software design techniques of the data acquisition system. By using the A/D, D/A conversion technique of the sound card，MATLAB and its data collection toolbox, this paper has presented a cost-effective data collection and analysis design based on the sound card, and analyzed and described thoroughly the course and methods of data collection and analysis system The system has advantages of easy operating，a simple human-computer interface, making it more user-friendly and can also be extended according to the needs of users. Finally, this paper has provided some examples which have applied this data collection
