Why does my code use so much memory, and how can I fix that? It begins to cause my computer to lag and even sometimes freeze.

Here is the code:

import ddf.minim.analysis.*;

import ddf.minim.*;

Minim minim;

AudioInput in;

FFT fft; //fast fourier transform - splits up sound wave in a selection of bands

int w;

PImage fade;

int hVal;

float rWidth, rHeight;

void setup()

{

size(640, 480, P3D);



minim = new Minim(this); //initializing minim object

in = minim.getLineIn(Minim.STEREO, 512); //initializing in

fft = new FFT(in.bufferSize(), in.sampleRate()); //initializing fft

fft.logAverages(60, 7); //values tested and work to spread out frequencies

stroke(255);

w = width/fft.avgSize(); //going to divide the width of the sketch by the amount of the bands in the spectrum

strokeWeight(w);

strokeCap(SQUARE); //get rid of the curved caps



background(0);

fade = get(0, 0, width, height); //load fade image with the contents of the background

rWidth = width * 0.99; //makes 99% as wide as the sketch

rHeight = height * 0.99; // ^^ but height

hVal = 0;

}

void draw()

{



background(0); //clean screen each time



tint(255, 255, 255, 254); //everything drawn is tinted white

image(fade, (width - rWidth) / 2, (height - rHeight) / 2, rWidth, rHeight);

noTint();





fft.forward(in.mix); //mix from left to right and form fft on audio input



colorMode(HSB); // Hue Saturation and Brightness.. to cycle through a rainbow of color

stroke(hVal, 255, 255);

colorMode(RGB);



for(int i = 0; i < fft.avgSize(); i++) //pulling the values from each band from the fft object and putting them on the screen

{

line((i * w) + (w / 2), height, (i * w) + (w / 2), height - fft.getAvg(i) * 4);

}



fade = get(0, 0, width, height);



stroke(255);



hVal += 2;

if(hVal > 255) {

hVal = 0;

}

}

THANK YOU FOR THE HELP!!
