Highlights
With the continuous innovation and progress of digital electronic technology, network technology, embedded technology and communication technology, the human life is undergoing a dramatic changing
After a clear understanding of the different stages of the audio player design, we must complete the corresponding task at each stages, the process mainly is the design of hardware circuit and software hierarchy
The WAV audio player uses MK20DX128VLH7 as the core control unit, it receives the audio files from the PC and to decode audio files and plays them
Summary
With the continuous innovation and progress of digital electronic technology, network technology, embedded technology and communication technology, the human life is undergoing a dramatic changing. A cutting system of WAV audio player based on embedded technology is designed in this paper, its function is reliable, the cost is low, the volume is small and the power consumption is low. There are many kinds of solutions to design audio player, but it still has a lot of room to improve in the overall power consumption, performance and sound quality. The designed player is combined with the characteristics of the existing audio player and takes its essence to enhance the overall performance, and it has a certain practical significance [2]
