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 to a range in which the human ear
is less sensitive.
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 Digidesign control
surfaces for mixing in Pro Tools:
Digidesign’s D-Control and D-Command (Pro Tools
HD Only) Innovative tactile worksurfaces that
employ a familiar, intuitive channel strip/center
section console layout.
Digidesign’s Control|24 (Pro Tools HD and LE
Only) Dedicated controller that provides access
to most Pro Tools recording, mixing, editing,
signal routing, plug-in control, and automation
features.
Digidesign’s Command|8 Low cost USB-based
control surface for Pro Tools. Command|8 is a
compact, convenient, and flexible control sur-
face for Digidesign-qualified Pro Tools systems.
