Triangular dither
WebIn the case of music, a dithered signal is preferred over undithered at a 4 bit level of resolution, but for 6-10 bit undithered is preferred. Rectangular PDF dither is preferred over triangular PDF dither for all resolutions. For speech, dithered is preferred at 4-8 bits. For higher resolution undithered is preferred. At 4-6 WebThat refers to what’s essentially EQ for dither, which is designed to change the frequency characteristics of dither noise so that it’s in a range that’s least audible to the human ear. All the Waves L-Series Limiters, such as this L3 Multimaximizer , are equipped with IDR technology for adding dither.

Triangular probability density function (TPDF) dither noise has a triangular distribution; values in the center of the range have a higher probability of occurring. Triangular distribution can be achieved by adding two independent RPDF sources. Gaussian PDF has a normal distribution. See more 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, … See more …[O]ne of the earliest [applications] of dither came in World War II. Airplane bombers used mechanical computers to perform navigation and bomb trajectory calculations. Curiously, these computers (boxes filled with hundreds of gears and cogs) performed … See more Dithering is used in computer graphics to create the illusion of color depth in images on systems with a limited color palette. In a dithered image, colors that are not available in the palette are approximated by a diffusion of colored pixels from within the available palette. … See more • Anti-aliasing (disambiguation) • Color quantization • Jitter See more Dither is utilized in many different fields where digital processing and analysis are used. These uses include systems using digital signal processing See more In an analog system, the signal is continuous, but in a PCM digital system, the amplitude of the signal out of the digital system is … See more Stimulated Brillouin scattering (SBS) is a nonlinear optical effect that limits the launched optical power in fiber optic systems. This power … See more WebWhen dithering a copy of the Alpha Channel, so you can dither it using either "-monochrome", or "-remap", make sure the image is a pure grayscale image, and not a shape mask containing transparency.

WebApr 9, 2012 · All this debate is a red herring, though. Just stick with simple "triangular" dither, and you'll be fine. After all, it's just noise - and very quiet noise, at that. All your favourite recordings from the 50s to the 90s were bathed in hiss - and they still sounded great. And that hiss was at a much higher level than any dither.
