no audio interface i have ever heard of does dithering. ardour does
dithering only on export to a bit-reduced disk file (e.g. 16 bit sample
format). ardour attempts (and generally succeeds) at being a perfect
bits-in = bits-out. jack offers dithering options but only if the user
requests them and even then only if the h/w format is bit-reduced from
the implicit 24 bit format of 32 bit floating point. and of course,
dithering by jack is only on output.
