Dither is a technique used in digital imaging and audio to create the illusion of color depth or sound quality. It involves adding random noise to a signal, which helps to reduce the appearance of banding or quantization errors. This is particularly useful in situations where limited color palettes or bit depths are used, as it can make transitions appear smoother. In the context of digital art and music production, dither can enhance the overall quality of the final output. By introducing subtle variations, it allows for a more natural representation of colors or sounds, making the experience more enjoyable for the viewer or listener.
