Dither in Pro Tools
There are several dither options provided in
Pro Tools. Each has a specific application within
the various operations that could benefit from
dithering.
In addition to the TDM, RTAS and AudioSuite
dither plug-ins, Pro Tools has a built-in dither
capability.
Dither Mixer Plug-ins (Pro Tools HD Only)
There
are two Mixer plug-ins that feature dither with
noise shaping: Stereo Dithered and Surround
Dithered. For more information, see the
Pro Tools|HD Getting Started Guide . Standard Ste-
reo and Surround Mixers do not have dither and
require use of dither plug-ins.
Dither on Final Output for Mixdown
You can in-
sert a real-time dither plug-in on a Master Fader
that controls your output mix, to dither your fi-
nal mix for CD or other 16-bit media. Inserts on
Master Fader process post-fader. This form of
dithering lets you use dither plug-ins from
Digidesign or third-party manufacturers. When
using the Bounce to Disk, see “Dither and
Bounce to Disk” on page 744.
AudioSuite Dither
For AudioSuite plug-in pro-
cessing, dither is based on the Dither plug-in.
For most AudioSuite plug-ins, dither can be au-
tomatically applied in the Processing Prefer-
ences page. The Use AudioSuite Dither check-
box enables a preset, N-shaped dither.
The following AudioSuite plug-ins can automat-
ically apply dither when processing:
• EQ III
• Compressor II
• Limiter II
• Gate II
• Expander/Gate II
• Normalize
• Gain
• DC Offset Removal
• Time Compression/Expansion
• Pitch Shift
Fades and Crossfades
In the Fades dialog (Edit >
Fades > Create), the Use Dither option enables a
preset, noise-shaped dither.
