hi

i am very new to processing enviroment and i have a very simple and basic question..

i am using minim.FFT to find the peaks from an audio source.

how i can everytime compare the last two peaks in order to  find how much time has
passed since another peak occurs.

i tried to store the values to an array and then compare the elements but had no lack.

i know its simple  but i dont have the programming knowledge yet to do this.

here is a part of my code that i have stucked to

fft.forward(player.mix);//FFT ON THE BUFFER

for(int i=0;i<spectrum.length;i++)
{
 
spectrum[i] = (fft.getBand(i));//FILL THE ARRAY WITH THE SPECTRUM

line(i,height,i,height-fft.getBand(i));//DRAW THE SPECTRUM

if ((fft.getBand(i)>fft.getBand(maximum))&&fft.getBand(i)>120)
{
  maximum=i;
  currMaxBand = fft.getBand(maxim);
  count=millis()-start;

}

}
start = millis();

my purpose is to find the the time that every maxband lasts.

can anyone help me?

Thank you..
