Noise Shaping
Noise is an integral part of the dithering process.
Noise shaping can further improve audio perfor-
mance and reduce perceived noise inherent in
dithering. Noise shaping utilizes digital filtering
to move noise from frequencies around 4 kHz to
near the Nyquist frequency. Essentially, noise
shaping lessens our perception of the noise in-
herent in dithering by shifting audible noise
components into a less audible range.
Noise Shaping is available in the Dither plug-in.
Using a Control Surface with
Pro Tools
Control surfaces add hands-on control to
Pro Tools functions. You can use a control sur-
face to adjust on-screen faders and knobs, acti-
vate transport controls, or scrub and shuttle in
Pro Tools.
There are several optional control surfaces for
mixing in Pro Tools:
• Digidesign’s D-Control, an innovative tactile
worksurface that employs a familiar, intuitive
channel strip/center section console layout.
• ProControl and Control|24, dedicated con-
trollers that provide access to Pro Tools re-
cording, mixing, editing, signal routing, plug-
in control, and automation features.
• Digidesign’s Command|8, a low cost USB-
based control surface for Pro Tools, developed
in a collaboration between Digidesign and Fo-
cusrite. Command|8 is a compact, conve-
nient, and flexible control surface for
Pro Tools systems running on Windows XP or
Mac OS X.
