Dither
(TDM and RTAS)
The Dither plug-in minimizes quantization arti-
facts when reducing the bit depth of an audio
signal to 16-, 18-, or 20-bit resolution.
Whenever you are mixing down or bouncing to
disk and your destination bit depth is lower
than 24-bit, insert a dither plug-in on a Master
Fader track that controls the output mix.
Using a dither plug-in on a Master Fader is pref-
erable to an Auxiliary Input because Master
Fader inserts are post-fader. As a post-fader in-
sert, the dither plug-in can process changes in
Master Fader level.
The Dither plug-in has user-selectable bit resolu-
tion and a noise shaping on/off option.
For more advanced dithering, use the Digi-
Rack POW-r Dither plug-in. See
Chapter 11, “POW-r Dither.”

For more information on using Dither, see
the Pro Tools Reference Guide.
If you are mixing down to an analog desti-
nation with any 24-bit capable interface,
you do not need to use Dither. This allows
maximum output fidelity from the 24-bit
digital-to-analog convertors of the interface.
