| Abstract: | Based on DSP technology and LabVIEW multithread-ing, this paper brings forward a low price solution of sound card based data acquisition and analysis system, with its advantages of easy implementation, friendly interface and steady perfor-mance. In the range of voice frequency, data saving and over-loading is successful in LabVIEW. If more sound cards config-ured in a PC, it' s feasible to build a multi-channel real-time DAQ system with high SNR. With broad application prospect, this solution can be extended to the field of speech recognition, ambient noise monitoring and laboratory measurement etc. |
