Noise reduction is a signal processing technique designed to minimize or eliminate unwanted background noise from audio, video, or data streams while preserving the integrity of the primary signal. This process enhances clarity, improves signal-to-noise ratio, and ensures the desired content remains prominent without distortion. According to Wikipedia, noise reduction techniques have evolved significantly from analog tape systems to sophisticated digital algorithms, with the first widely used audio noise reduction technique developed by Ray Dolby in 1966. What is noise reduction fundamentally refers to the process of distinguishing between desired signal components and unwanted noise, then applying selective filtering to reduce the noise while maintaining the signal's essential characteristics. In professional audio production, effective noise reduction can improve signal clarity by up to 20dB, significantly enhancing listener experience and content quality. The goal is never to remove all noise, but to achieve a balance where the signal remains natural and unprocessed.
