Dither is a technique used in digital imaging and audio processing to create the illusion of color depth or sound quality. By adding small amounts of noise, dither helps to reduce the appearance of banding or distortion that can occur when converting high-resolution images or audio into lower resolutions. This process makes transitions between colors or sounds smoother and more natural. In digital art, dither can be applied to images to enhance visual quality, especially in formats with limited color palettes. Similarly, in audio, dither is used during the process of bit depth reduction to maintain fidelity and prevent unwanted artifacts.
