This project plays with sine wave in Processing, with the help of the sound library, I create a sine wave movements corresponding to the rhythm of the song.
With the property extracting by the sound library, such as the volumes and the frequency, it determines the sine wave's frequency. The colors corresponding to the leading frequency of the song, if it is high freq, the color will be more reddish, if it is at middle freq, the wave will be more close to green colors, otherwise, the blue color.
