In the Cubase manual yes it says it’s used for dithering, whatever that is, and also that it should be applied post fader. But it doesn’t say much else so maybe you can spare some minutes of your time and actually answer some of my specific questions:
a) What exactly does dithering do?
b) Do I use it in every instrument bus or in a final bus (a bus before the global ‘stereo out’ bus) ?
c) Do I use it during mixing or is it intended to be used for mastering, as in, to use on a final track that you have previously exported as your final mix?
Thank you for your time.
