Music: Butter-BTS!!!!!!!

代码：

FFT fft;

void setup()
{
size(800, 640, P3D);
minim = new Minim(this);

}

void draw()
{
background(255);

for(int i = 0; i < fft.specSize( )*0.002; i++)//use i<xx times a number to adjust the degree of density
{
stroke(255);
rect(random(50,800), random(50,640), fft.getBand(i)/200-600, fft.getBand(i)/200-600);//use random to
fill(random(200),fft.getBand(i)+300,240,fft.getBand(i)+100);//high values will result in higher saturation. The fourth number is bu tou ming du.
}
delay(700); //how to let the beat fit?
}
