Craig, excellent info.
If am mastering tracks imported spdif from DAT tapes, that are finished mixes,
(transfered from two-rack 1/4 inch master, recorded live in a real studio with a real engineer)
should I apply a DC offset filter to that stuff too ?
(I have a couple of more "home made" tracks that make a nasty glitchy sound at the beginning or end . I guess those really need it. )
And Dither ?
Otherwise I am inclined not to mess with it much.
