| Hello!
Have used but don't currently have SF. Think it was version 6. Have downloaded the manual on the website instead, to see what the options are, and what they write about them. Turns out we're both correct.
What I did was to create a sine wave in 24 bits, dither & truncate to 16 bit and watch the results on the spectrogram option. All within the program. Most of the options did not remove the truncation noise, there was still semirandom spikes of energy in addition to the sine and the noise. So I figured there was something wrong with the dither!
At that time, I hardly knew what dither was, only what it was supposed to do. Noise distribution was an incomprehensible word. Looking at the manual now, it is obvious that they've put in several noise distribution options that does not give proper dithering. "It's not a bug, it's a feature!" That caught me out and led me to believe that there was something wrong.
The correct thing to say would be that most of the available dither options are not random enough to totally avoid the truncation artifacts. Though you probably knew that anyway.. :)
