dither
In digital recording and signal processing, dithering is a mathematical process where a random noise is added to the least significant bit of a digital word With very low level signals, the quantization error becomes correlated to the signal level This creates a measurable amount of distortion By adding dither, the correlation between the signal level and the quantization error is canceled, allowing the digital system to encode amplitudes smaller than the least significant bit If you change the word size as a signal passes from one digital system to another, being able to add dither allows you to maintain a high quality signal
act nervously; be undecided; be uncertain
Low-level noise added to the signal to reduce the effect of quantization error
{i} state of confusion, extreme agitation or excitement; vacillation, hesitation

Dither is a process through which exta bits in the digital audio stream are removed Usually, it happens when there is a 20 or 24 bit converter going into a 16 bit device (like an SBM into a dat deck) Obviously, the extra bits have to go away, and there are different ways of doing it Many devices merely throw away the least significant bits, while others, such as Sony's Super Bit-Mapping, actually does sound analysis and shaping to produce the best possible dithering result
To convert an digitised image containing continuous tones, including colour, into one consisting of two colours only, usually black and white This is necessary for the image to be printed It is also possible to dither a coloured image into the four process colours: cyan, magenta, yellow and black, suitable for a colour printer
To approximate a color that is not part of the current palette by combining pixels of different colors close to each other Viewed from a distance, it gives the effect of the desired color, but viewed closely, the dots are visible Dithering can be avoided by selecting non-dithering colors that are compatible with different browsers
a process of changing the color value of a pixel to the closest matching color value in the palette; placing image pixels closer together to create the illusion of more colors than an image actually uses
Since a majority of graphics displays are still 8-bit (and can only display 256 colors simultaneously), special techniques are needed to display images with many more colors present Dithering simulates additional colors by juxtaposing two different colors to imply a new one An extreme example of dithering is the display of early Macintoshes, which approximated levels of grays by clusters of small black and white dots
To do something nervously
A slight up and down vibratory motion of the machine tool ram and attached electrode used to improve cutting stability
The mixing of adjacent pixels to simulate additional colors when available colors are limited, such as on an 8-bit monitor The positioning of different colored pixels within an image that uses a 256 color palette to simulate a color that does not exist in the palette A dithered image often looks noisy, or composed of scattered pixels
The process of approximating pixel colours when reducing the colour depth of an image Dithering can improve transitions between colours when reducing a 24-bit image to 8-bit format
To be uncertain or unable to make a decision about doing something
make a fuss; be agitated act nervously; be undecided; be uncertain
To simulate a color that is not part of the current palette on-screen (or in print) by combining pixels of different colors close to each other Viewed from a distance, it gives the effect of the color Viewed closely, the dots are visible Dithering can give a noisy appearance to a picture on-screen, but it often can be avoided by selecting non-dithering colors that are compatible with different browsers and platforms See RGB and Creating Small, Fast-Loading Graphics for Web Pages for more help with this DitheredcolorMagnified8 times
