| Abstract: | This paper introduces a digital audio- effect processing system based on TMS320VC5402. The article firstly brings out the general scheme of a digital audio - effect system, and makes a simple introduction of the chips used in the system. After that, hardware architecture block diagram and software processing flow are given. And a basic audio- effect algorithm is discussed at last. Experiments show that various audio effect algorithms can run well on this system platform. |
