I agree. Perhaps one of the dsp gurus (hint hint!) in the list will want
to take a look at the source? There are only a couple of places where
the denormal code is needed, it is actually there but for some unknown
reason it is not working. At some point I added a patch for that but it
did not work either. Working patches gladly accepted!!
