     115This block key is "SP".[[BR]]
     116This block contains a pointer to the seek table block.

     131- The reference for the seek size is the musepack magic number[[BR]]
    120132- The first 2 values are stored using the same code as the block length code.[[BR]]
    121133- The next values are coded as :[[BR]]
    122134code = value(n) - 2*value(n-1) + value(n-2)[[BR]]
    123 the 1 bit is sent for code sign, and the absolute value of code is sent as golomb code with k=10. A log code, as Fibonacci or Elias may be better, but golomb is easier to implement.
     1351 bit is sent for code sign, and the absolute value of code is sent as golomb code with k=10. A log code, as Fibonacci or Elias may be better, but golomb is easier to implement.
