英文摘要：

The design of hardware circuit to study various of audio algorithms has the disadvantage of long development cycle, high cost, inconvenient for flexible modification algorithm. The digital sound system is designed with the function of Schroeder reverb, chorus, flange and echo sound by using Simulink audio processing module, subsystem, packaging tech- nology and Matlab library. It is introduced that the concrete steps of the system design, parameters and the methods of the au- dio module. The results show that the sound model layer is clear and the visualization can flexibly set parameters, which can effectively help engineers and technicians to accelerate the research and development of the various audio effect algorithms.
