Stuart, I don't think it would care because the Dragon only looks at the right channel. Please look at the link below. It splits it in half and then does a comparison for maximum HF. Then, for your access copy you fix your problem in the DAW and notate the preservation copy as having that defect which was fixed in the access copy. Martin, You're welcome!

It adjusts over a more limited range than the wide ranging field (especially oral history) cassettes that I've had to digitize, so it is not a cure-all.

NAAC generally does NOT readjust in the middle of a tape in my experience--although I may have caught it doing it once or twice, it doesn't seem to do it when I'd want it. > > Here is the explainer on how the Dragon's NAAC works (and other things about this interesting machine). > > https://www.dropbox.com/s/ca8ksp4q6gga35k/Nak_dragon_folder.pdf?dl=0 > > Cheers, > > Richard > > On 2019-07-25 12:42 p.m., Martin Fisher wrote: >> I haven't done exhaustive research into Nakamichi decks but if anyone can either point me to something that describes how the azimuth correction works on these decks (not azimuth theory but how the decks actually do the correction) I would be most grateful. I'm very wary of equipment that supposes it can do a better job than a discerning ear and even a modicum of common sense along with (and this is most important) caring enough to do it right. > -- > Richard L.
