[[Dither]] is a term used to describe a special form of wide-band noise which is added to digital audio signals to prevent distortion of low level signals; typically at the level of 1-2 [[lsb]]'s. The two common forms are: "Flat" and "Triangular" or "HPDF" (high pass probability density function), which both distribute the noise energy fairly evenly across the audible spectrum.

Overview
The term "αβC αcoustic βit Correction™" is a registered trademark of Lavry Engineering, Inc. which refers to a proprietary form of Noise-shaped dither.
Basics
Dither is a term used to describe a special form of wide-band noise which is added to digital audio signals to prevent distortion of low level signals; typically at the level of 1-2 lsb's. The two common forms are: "Flat" and "Triangular" or "HPDF" (high pass probability density function), which both distribute the noise energy fairly evenly across the audible spectrum. Noise shaping is a process where the noise energy is shifted away from the mid-range frequencies where the ear is most sensitive to the bass and upper treble regions.
