In this paper, the authors implement the reading of audio files, the process of the audio signal and the extraction of the left and right channels signal with the powerful function of digital signal processing in MATLAB. Combining with chip control requirements, the interface of FPGA and WM8731 was designed by Verilog HDL to transfer the audio data to the audio processing chip. Finally, the reliability of the design is verified by simulation and the analysis method of the simulation result in Quartus II is presented.
