These lines still add dither. The second time you offer a commandline
that doesn´t do what you decsribe it to do. You should check before
posting...
I´m really interested how you rate your resampling and why clipping is
a non-issue suddenly. Do you allow aliasing and how much aliasing? If
no aliasing, why not? What bandwith? Steep or slow Filter? What phase
response 10, 25, 30 or even 50? Dither yes or no and what kind?
What is the advantage/disadvantage of using the corresponding setting
with sox against iZotope and what settings exactly you choosed in your
comparison?
Since you give a recommendation i guess you checked all that?
There were several people before that even had deep knowledge about the
mathematics behind that stuff and no one can proclaim to know the "best"
way doing it because there isn´t.
