Realllllllllllllllllllllllllly?BTW, one of the best introduction I've heard is:…one of the earliest [applications] of dither came in World War II. Airplane bombers used mechanical computers to perform navigation and bomb trajectory calculations. Curiously, these computers (boxes filled with hundreds of gears and cogs) performed more accurately when flying on board the aircraft, and less well on ground. Engineers realized that the vibration from the aircraft reduced the error from sticky moving parts. Instead of moving in short jerks, they moved more continuously. Small vibrating motors were built into the computers, and their vibration was called dither from the Middle English verb "didderen," meaning "to tremble." Today, when you tap a mechanical meter to increase its accuracy, you are applying dither, and modern dictionaries define dither as a highly nervous, confused, or agitated state. In minute quantities, dither successfully makes a digitization system a little more analog in the good sense of the word.

It definitely still takes experience. My first masters were awful!all mastering is done by normal ears .. if sounds good it is good .. too much depth on this subject now as ive found out.
this is exactly true. If you cake on one dither after another, the dither noise will eventually become audible and thus defeat the purpose of it.with 32bit DAWs dithering is really only needed as the last stage when you go down to 16bit. interesting info, though.
