Research And Design Of Color Music System Based On Audio FFT

Listening to music as a more relaxed way of entertainment in daily life is very popular with people,and music player now seems to be an indispensable consumer goods in society.Therefore,the development of the music player is also more mature.In order to meet the different requirements of consumers there appeared a variety of different music players.According to the research on the market we can get a conclusion that young people as the main consumer groups prefer to the music player which flexible,innovative and with good sounds quality.But the products are often too simple,are not conducive to the subsequent expansion,therefore,it is a developing direction to design a new multi-function and have strong-expanding system with color matching.In recent years,there have been a variety of music players with light colors on the market,but it has not been fully realized in real time.Between the playing music and the changing light there is lack of a certain correlation,and the music is difficult to fully correspond with the color.A color music system that can be used to fill the blank space is required.The paper analyzes the audio FFT spectrum and designs a color music system based on FFT(Fast Fourier Transform),realizes an integrated system device that combing of playing music,colour matching and mixed RGB(Red Green Blue).This paper introduces a new experimental platform that realizing the complete matching of color and music.Starting from the tone of the essence,through the analysis of the relationship between the pitch intervals and then extending to the relationship between color.To improve and optimize the music player that on the market on the relationship between the color and music now,and to find the color corresponding to a certain scale of a certain tone.The mathematical theory has been applied to make the research more reasonable and reliable.Firstly,the functional modules and interface technology of the hardwarecircuit are studied,and then playing music is collected,the audio signal collected by FFT spectrum analysis and processing,the data were processed to get match colors,at last,the PWM(Pulse Width Modulation)driver RGB-LED(Red Green Blue-Light Emitting Diode)mixed light technology is used to complete the music playback system.A music player that can get the corresponding color and realize the effect of mixing after the analysis of the input audio signal is completed.The system not only can promote the development of music playback,but also has the use of the stage lighting,music therapy and other fields.In the paper,the research and design of the color music system based on audio FFT is basically completed.The study of dissertation has basically met the expected design requirements.It is proved that the performance of this project is unique,and it has some popularization value in usability and expansibility.
