The GIF format is a compressed, loss-less graphics format that supports only 256 colors. When saving in the GIF format, Photoshop dithering tries to simulate shading, making flat, colored areas appear patchy. Instead, Photoshop has to save the GIF image using the nearest of the 256 colors without using any dithering.

What is GIF dither no dither?

Dithering is the most common means of reducing the color range of images down to the 256 (or fewer) colors seen in 8-bit GIF images. Dithering is the process of juxtaposing pixels of two colors to create the illusion that a third color is present.

How many colors are in a GIF?

Does dithering make a difference?

And there you have it what you need to know about dithering. If your music includes wide, natural dynamics, proper dithering can indeed give a sweeter, smoother sound free of digital quantization distortion when you downsize to 16 bits.

Which noise is used for dithering?

The most basic form of dither is flat, white noise. The ear, however, is less sensitive to certain frequencies than others at low levels (see Fletcher-Munson curves).

What is dithering why does it occur how can it be avoided?

Dither is low volume noise, introduced into digital audio when converting from a higher bit-resolution to a lower bit-resolution. The process of reducing bit-resolution causes quantization errors, also known as truncation distortion, which if not prevented, can sound very unpleasant.
