Dynamic Range Control (DRC) is a technique used in audio processing to manage the difference between the quietest and loudest parts of a sound signal. By compressing the volume levels, DRC helps to ensure that softer sounds are audible while preventing louder sounds from becoming overwhelming. This is particularly useful in music production and broadcasting, where consistent sound levels enhance the listening experience. In addition to audio, DRC is also applied in photography and video to balance the light and dark areas of an image. This ensures that details are visible in both bright highlights and dark shadows, improving overall image quality. Techniques like HDR (High Dynamic Range) imaging often utilize DRC principles to achieve this balance.
