Also to take this example and look at the average buffer fullness for your
clock sync.
From frame 0 to frame 990 the buffer is empty. You can either 
A. set the per file average in a window to 0 which means that the buffer
   must always stay empty. A restriction rendering the systen useless.
B. set the average to some higher value but whichever you pick, that
   amount has to be in the buffer during the first 990 frames, thus
   requireing a very huge average preload to get this into the buffer.
