Automatically Create Click Track In
New Sessions
To have Pro Tools automatically create a click
track when you create a new session, enable the
Automatically Create Click Track In New Ses-
sions option in the MIDI Preferences page
(Setup > Preferences).
Dither
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 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.
Dither Controls
Bit Resolution
Use this pop-up menu to choose one of three
possible resolutions for the Dither processing.
Set this control to the maximum bit resolution
of your destination.
16-bit Recommended for output to digital de-
vices with a maximum resolution of 16 bits,
such as DAT and CD recorders.
18-bit Recommended for output to analog de-
vices if you are using an 18-bit audio interface,
such as the 888 I/O or 882 I/O audio interface;
this is the maximum resolution available from
the 18-bit digital-to-analog convertors of these
devices.
Selecting the Automatically Create Click Track In New
Sessions option in the MIDI Preferences page
For more advanced dithering, use the Digi-
Rack POW-r Dither plug-in. See “POW-r
Dither” on page 60.
Dither plug-in
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.
