Ditheröinti refers to a technique used in digital imaging, graphics, and audio processing to simulate the appearance of higher fidelity than is actually present. The term originates from the English word "dither," which describes the process of introducing controlled noise or variation to reduce visual or auditory artifacts, particularly in systems with limited resolution or color depth.

In visual contexts, dithering is commonly applied to images displayed on devices with a limited number of colors, such as early computer monitors or printers. By distributing small patterns of pixels—often in a checkerboard or dot-based arrangement—dithering creates the illusion of additional colors or shades that the system cannot directly display. This method helps mitigate banding, where abrupt transitions between colors appear unnatural. Two well-known dithering techniques are Floyd-Steinberg error diffusion and ordered dithering, each offering distinct approaches to achieving smoother gradients.

In audio, dithering involves adding a small amount of noise to a signal during conversion from a higher-bit-depth format to a lower one, such as from 24-bit to 16-bit. This process helps preserve the dynamic range and reduces distortion by masking quantization errors. Dithering is particularly important in professional audio production to maintain signal integrity when working with constrained bit depths.

The effectiveness of dithering depends on the context and implementation. While it can enhance perceived quality, excessive or poorly applied dithering may introduce unwanted artifacts. Modern systems with high-resolution displays and advanced audio codecs often rely less on dithering, though it remains a valuable tool in legacy and constrained environments.
