i could hardly believe that, but you are right! i have just created a
file with writesf~, ensured that it contained only zeros (hexeditor),
loaded it in audacity, exported as 16bit wav, and after normalizing,
there was a lot of noise.

dithering maybe? i have checked with another editor (mhwaveedit), and
it did not add noise. so using another editor would be a solution. or
saving in another format than 16bit wav ("other uncompressed format"
in audacity), you would need another program to convert the file for
buring on cd (or whatever) though.

bis denn!
