This page has an interesting story of wave-files and how they came into
Quote: "Furthermore, there are lots of inconsistencies, for example how
8-bit data is unsigned, but 16-bit data is signed."
If you do have covered this (I read through your patch, but could not find
it - could be my coding skills), or if the dsp chip has covered this,
then.. ah well, the wave file story is still interesting. :-)
