| Abstract: | With rapid development of MCU technique, microprocessor and microcomputer are widely used. They are also used in audio and video technology extensively. This project process the sound signal utilized digitally audio processor. MCU technique and virtual instrument technique were utilized to delay the mike input signal, adjust sound channel, etc. The digitally audio processor supported I^2C bus which was simple and effective. Soft panel programmed by LabWindows/CVI was very friendly and wieldy. |
