being concerned mainly interface issues thus far, i'm not
100% sure myself.  i have loaded and saved a 16bit stereo
48000hz wav file and the data is identical. i've also dissected, saved
then reassembled the same wav and the resulting file still
has identical data. i'll look at the source later to try and
confirm that sweep doesn't convert data internally but
perhaps Conrad,Erik: if either of you could confirm one way
or the other?.
(i seem to remember Thorsten Wilms asking this a while back
too and i forgot to check my big ole list of things not to forget.)
