Volume is the linear
          difference between sound intensities. 64 is full volume, and
          the change in decibels can be calculated with 20*log10(Vol/64)
2         Start of sample repeat offset in words. Once the sample has
          been played all of the way through, it will loop if the repeat
          length is greater than one. It repeats by jumping to this
          position in the sample and playing for the repeat length, then
          jumping back to this position, and playing for the re
