I use MBIT+ exclusively for dithering.
Noise Shaping: Ultra
Dither Amount: Normal
After you dither you then have to Save As... with the *new* bit depth. So if you have a 24/48 file you would resample first, then dither, then save as 16/44.1
This has always slightly confused me about the MBIT+ for dithering.
Seems that any other plugin, I've used/seen that deals with bit depth
or sample rate conversions will display the result in the lower right
corner of the screen (using Wavelab 5) once it completes. MBIT+
does not do this.
If you have to save as with the new bit depth, what process is really
being used for dithering? Not sure about SF but Wavelab will dither
and resample just by simply adjusting the settings in the save as dialog,
no third party plugin required.
So I run MBIT+ with no indication of success (ie, bit depth is not updated
on the screen) then I do a save as. Which step actually performed the
dithering?
