%X The algorithm of audio compressor is analysed. Especially describle how to process two parameters： attack time and release time. The algorithm is checked by MATLAB. DSP chip TMS320VC5501 and Microcontroller Unit STC89LE58RD are used as cores to set up the platform. Hardware design and software design are given. The compressor is tested by the same audio source which is used in the MATLAB. Compare the result of MATLAB with of compressor and mean error between them is only 0.38%. So the correctness of this design is proved and meets the need of high accuracy of audio comprssor. This design can be seen as a new way to high-accuracy audio compressor.
