Could anyone advise me on this subject: In T-Racks 5, we have two ways of applying Dithering. If I use the Dithering on the Stealth Limiter, should I apply dithering when exporting a file from 32bit to 16bit as well?
As far as I know the rule is "Dither once". So if you've set dithering in the limiter, the dither noise will be added to the signal pre export. Assuming the limiter is the last thing in your mastering chain, and you have set dithering on, then leave it off in the export settings. It's a matter of taste in what sounds better.
