void setup() {
 size(256,200);

 // start up Ess
 Ess.start(this);
 
 // get ready to stream KCRW
 // (Ess.READ does not require a sample rate)
 myFile=new AudioFile("http://64.236.34.67/stream/1046",0,Ess.READ);

 // create a new AudioStream and set the sample rate
 myStream=new AudioStream(32*1024); // 32k samples
 myStream.sampleRate(myFile.sampleRate);

 myStream.start();

 framerate(30);
}

   int top=50;



 ***************************************************  
   if (i+interp<myStream.buffer2.length) top-=(int)(myStream.buffer2[i+interp]*50.0);    

//THIS LINE  CAN ANYONE PLEASE EXPLAIN FROM AFTER THE "IF" STATEMENT.

   int j=0;
   for (int k=top;k<height;k++) {

   }
 }
}

void audioStreamWrite(AudioStream theStream) {
 // read the next chunk

 int samplesRead=myFile.read(myStream);
 if (samplesRead==0) {
   // start over

   myFile.close();
   myFile.open("http://www.tree-axis.com/temp/vindaloo.mp3",myStream.sampleRate,Ess.READ);

   samplesRead=myFile.read(myStream);
 }
}

// we are done, clean up Ess
