Sure it is undithered?
The files were generated using Audition, and if you trust there is no bug, then it is undithered.
So, sample value created by way of "multiplying sample number by 2pi to certain precision" and getting different round-off every now and then?
Audition 1.5 was a 2004 product which is no longer supported, and I am not good enough to reverse engineer their code.

Within freewares I know, apart from foobar, Audacity and SoX also support tone generation, so you can try to generate some files and compare them.

-D for no dithering. Differs a little from yours, so there is a "not exact scine'nce" pun waking here.
At least each one-second chunk is identical for this one (edit: not sure if that is a good thing for testing ...), but still it xz's to bigger than yours.
