De-noise refers to the process of removing unwanted noise or interference from a signal, image, or audio recording. This technique is commonly used in various fields, including photography, music production, and telecommunications, to enhance the quality of the final output. By filtering out background noise, de-noising helps to clarify the main subject, making it easier to analyze or enjoy. In digital imaging, de-noising algorithms can improve the clarity of photos taken in low-light conditions, where graininess is often an issue. Similarly, in audio processing, de-noising tools can eliminate hiss or static from recordings, resulting in a cleaner sound. Overall, de-noising is essential for achieving high-quality results in both visual and auditory media.
