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. WebThe simplest form of the algorithm scans the image one row at a time and one pixel at a time. The current pixel is compared to a half-gray value. If it is above the value a white pixel is generated in the resulting image. If the pixel is below the half way brightness, a … crosswater kitchen sink taps
