Dither

Dither is an intentionally applied form of noise used to randomize quantization error, preventing large-scale patterns such as color banding in images. Dither is routinely used in processing of both digital audio and video data, and is often one of the last stages of "mastering" audio to a CD.

A typical use of dither is converting a greyscale image to black and white, such that the density of black dots in the new image approximates the average grey level in the original.

Etymology

The term "dither" was published in books on analog computation and hydraulically controlled guns shortly after the war. The concept of dithering to reduce quantization patterns was first applied by Lawrence G. Roberts in his 1961 MIT master's thesis and 1962 article though he did not use the term dither. By 1964 dither was being used in the modern sense described in this article.

In digital processing and waveform analysis

Dither is often used in digital audio and video processing, where it is applied to bit-depth transitions; it is utilized in many different fields where digital processing and analysis are used – especially waveform analysis. These uses include systems using digital signal processing, such as digital audio, digital video, digital photography, seismology, RADAR, weather forecasting systems and many more.

Dither (album)

Dither is the fifth studio album by the American rock band moe. It was released on February 6, 2001 on the band's new, self-owned label Fatboy Records. It was their first album after their split with former label Sony BMG. It was recorded in several studios around the country, from the summer of 1999 through the summer of 2000. The album features guest appearances by DJ Logic, Kirk Juhas, and the Nykw-ILL bros.

Reception

Rolling Stone magazine noted that most of the songs are "airtight groove-adelia, compact essays in twin-guitar sunshine and boyish-vocal cheer" and that the album is "muscular guitar pop with room for rambling." The Jambands.com review also says the song placement was "usually complementary, although [occasionally cluttered]" but noted that "when everything falls into place ... the disc is captivating"; Allmusic was more critical of the structure, however.
