Split Audio file
Jun 6th, 2010, 12:12pm  
Hello, I'm very new to Processing so bare with me.  I am trying to split an audio file into different files of equal length.  I have been looking at some of the audio libraries but none that I have seen help in this scenario.  Could some one guide me in the right direction.

My biggest issue is how do I pass the contents of an audio file into a byte array and loop.  
Any help would be greatly appreciated. This doesn't work but at least you can see what I am trying to do.

Code:

void setup(){
	  size(256,200);
	  
	  byte b[] = loadBytes("resistance.mp3");
	  println("Song Byte Length: " + b.length);
	  
	  
	  // print each value, from 0 to 255 
	  for (int i = 0; i < b.length; i++) { 
	   byte[] c = new byte[1000000];
	   if(boolean(b[i])){
		 c[i] = (byte)(b[i]);
	   }
	    if( (i % 1000000) == 0){
		  saveBytes("First-" + i + ".mp3",c);
		  println(i + ": File");
	    }
	  }
	 
	  // print a blank line at the end 
	  println("Done");

is this what you want

void setup(){
 size(256,200);
 byte b[] = loadBytes("_____________.mp3");        
 println("Song Byte Length: " + b.length);              
 // print each value, from 0 to 255      
// this part was moved      
byte[] c = new byte[10000000];
 for (int i = 0; i < b.length; i++) {

   if(boolean(b[i])){            
     c[i] = (byte)(b[i]);
   }      
   if( (i % 1000000) == 0){
     saveBytes("First-" + i + ".mp3",c);            
     println(i + ": File");      
   }        
 }
 // print a blank line at the end      
 println("Done");
}

//you were making an alot of arrays that was 1000000 . java
// doesn't like that
