dithering    音标拼音: [d'ɪðɚɪŋ]

dithering
n 1: the process of representing intermediate colors by patterns
of tiny colored dots that simulate the desired color

A technique used in {quantisation} processes
such as {graphics} and {audio} to reduce or remove the
correlation between noise and signal.

Dithering is used in {computer graphics} to create additional
colors and shades from an existing {palette} by interspersing
{pixels} of different colours. On a {monochrome} display,
areas of grey are created by varying the proportion of black
and white pixels. In colour displays and printers, colours
and textures are created by varying the proportions of
existing colours. The different colours can either be
distributed randomly or regularly. The higher the
{resolution} of the display, the smoother the dithered colour
will appear to the eye.

Dithering doesn't reduce resolution. There are three types:
regular dithering which uses a very regular predefined
pattern; random dither where the pattern is a random noise;
and pseudo random dither which uses a very large, very
regular, predefined pattern.

Dithering is used to create patterns for use as backgrounds,
fills and shading, as well as for creating {halftones} for
printing. When used for printing is it very sensitive to
paper properties. Dithering can be combined with
{rasterising}. It is not related to {anti-aliasing}.

  • What is the difference between dithering options at mixing down export . . .
    When this option is turned on, SONAR uses dithering when you export a higher-bit file at a lower resolution, or lower the bit depth of a project’s audio files by using the Tools > Change Audio Format command, or when you “render” audio (bounce, freeze, or apply effects) SONAR Producer offers five kinds of dithering: Rectangular
  • dithering - Cakewalk Forums
    dithering I have a question about the dithering option under the audio menu I have always left the defaults to triangular What is this used for and what effect would it have if I changed the pattern? Is this just for exporting to 2 channel wave files?
  • SONAR - Dithering - Cakewalk Forums
    stratman70 Dithering has always caused me some indecision Well, first of all don't lose sleep over it Despite what people might say, the differences are fairly subtle (remember that when it comes to audio, people tend to think every difference is either inaudible or a huge night and day difference - there seems to be no middle ground)
  • In your opinion what is the best setting for dithering? Why?
    Dithering is ONLY applied during a bounce, freeze or export operation when a bit depth (wordlength) reduction takes place Sonar DOES NOT dither during playback or when the wordlength are the same Hi Jose, So in Sonar-4, if I have a 16-bit project with a Soft-Sampler that has a mixture of 16 and 24-bit samples, should I have dithering turned on?
  • Dithering. . . ? - Cakewalk Forums
    Hi All What does Dithering actually do ? I noticed several different types in the Export Auido menu And do you need to Dither when you bounce render soft synths down to Audio [save Cpu]
  • Dithering. . . When and how to apply? | Cakewalk Forums
    Hey there I thought I had a grasp on dithering these days but suddenly I'm a little confused on when and how to apply it This post is a little wordy so please bare with me Here are some scenarios that I would like to clarify Each one is done by exporting a mix from Sonar 6 2 1 All my project
  • Power 1, 2, or 3 | Cakewalk Forums
    If Dithering is making your music sound weak, then its not the dithering The differences between POW 1 thru 3 are so subtle, it cannot make something that was powerful into something weak It just cant all it does is add a bit of harmonic distorion so you cant notice the bits getting cut off, in very very simple terms
  • Which dithering setting do you use? | Cakewalk Forums
    Read Izotopes guide to dithering - it's available as free download - that is a very useful tool to assist you in the selection of algorithms -D post edited by DonM - 2007 01 15 09:17:06
  • Q: Should I Dither when Rendering Stems? | Cakewalk Forums
    The following was lifted from the "Dithering" topic in Sonar's online help: "Dithering--whenever an audio signal is converted from a higher-bit resolution to a lower resolution, it is necessary to apply dither to avoid introducing undesirable quantization noise or harmonic distortion into the signal
  • Dither: Pow-r 3 vs Triangular? | Cakewalk Forums
    Hi So I'm exporting to CD from 24 bit 48khz I'm reading conflicting reports about dithering For quality Sonar help implies Triangular is the most accurate best dither However other documentation recommends Pow-r 3 Any thoughts on
