| Abstract: | A kind of visual audio signal acquisition and analysis system based on the MATLAB is designed and developed.The system has realized the real-time audio signal acquisition at a lower cost by the sound card of Realtek Ac'97 and MATLAB's Data Acquisition Toolbox,and accomplished audio signal analysis with high precision using MATLAB's powerful calculation and signal processing abilities.The system is optimized by MATLAB's GUI,which takes advantage of simple dialog box and menu operation instead of complex program modification and debugging,and makes the usage of the system more convenient and flexible. |
